The Interpretation of 5G Related Terms

Since the end of last year, the heat of the word "5G" has remained high. As a cutting-edge communications technology, 5G has many terms. Due to the oversimplification and nastyness of the names of standards, specifications, and technologies adopted by various institutions and the complexity of 5G technology itself, there are many similar and confusing phenomena in these terms. This article will help you sort out and explain common 5G terms.

5G: IMT-2020


IMT-2020 is a term developed by the ITU’s Radiocommunication Sector in 2012 to develop the vision of “IMT for 2020 and beyond.” The ITU has set a timeline that calls for the standard to be finished in 2020. Additionally, the name IMT-2020 follows the same naming structure as IMT-2000 (3G) and IMT-Advanced (4G). In early 2017, ITU representatives partnered with academia and research institutions to complete a series of studies focused on the key 5G tech and performance requirements for IMT-2020.

5G: 3GPP R15/R16


3GPP, short for 3rd Generation Partnership Project, is an international communications organization. There are four types of members: organization members, market representatives, observers and special guests. Organization members include ARIB (Association of Radio Industries and Businesses), ATIS (Alliance for Telecommunications Industry Solutions), CCSA (China Communications Standards Association), ETSI (European Telecommunications Standards Institute), TSDSI (Telecommunication Standards Development Society of India), and TTA (Telecommunications Technology Association) and TTC (Telecommunication Technology Committee). Market representatives include 18 members such as 4G Americas, 5GAA and GSM Association. Observers include 3 members such as ISACC. Special guests include 27 members such as CITC and Netgear.

The 3GPP will regularly publish new wireless communication technology standards. The Release 15 (R15) is the first version that includes the 5G standard. According to the plan, the second stage of the 5G, that is, the R16, will be completed in the fourth quarter of 2019.

5G: NR


NR is short for New Radio. The technical topics involved are complex, but in simple terms, NR is a new standard for data communication between wireless devices and base stations.

5G NR

The communication between the device and the base station is wireless, and the communication medium is a radio that propagates in the air. The NR is a new type of interface for wirelessly transmitting data in the air.

5G: mmWave


The mmWave, millimeter wave, is an electromagnetic wave with a frequency of 30GHz to 300GHz, and the frequency band is between a microwave and an infrared wave. Millimeter waves applied to 5G technology range from 24GHz to 100GHz. With extremely high frequency, the mmWave supports a very fast transmission rate. At the same time, its higher bandwidth also allows operators to choose a wider range of frequency bands. You need to know that there are fewer and fewer bands that are idle now.

5G frequency band

However, the mmWave is not perfect, and its ultra-short wavelength (1mm to 10mm) makes it weak to penetrate objects, which leads to signal attenuation. These objects include air, fog, clouds, and thick objects.

Fortunately, the development of communication technologies in recent years has led people to find a way to overcome the short transmission distance of mmWave. One way is to increase the number of base stations directly. Another method is to send electromagnetic waves to the same line through a large number of small antennas to form a focused beam that is powerful enough to extend the effective transmission distance.

Short wavelengths also have advantages. For example, short wavelengths allow the transceiver antenna to be made small enough to be easily plugged into the handset. Low-volume antennas also make it easier to build multi-antenna combo systems in confined spaces.

5G: LDPC


LDPC is short for Low Density Parity Check Code. It is a linear error correction code. It can effectively, accurately and reliably detect whether the data transmitted between devices is correct or not. This capability allows LDPC to be gradually applied to wireless data transmission in complex interference environments.

Common (n, k) LDPC Graphical Expressions

5G: Polar Code


Polar Code is a kind of linear block error correction code. Its role is the same as LDPC. It guarantees the correctness and completeness of data transmission. Polar Code and LDPC each have their own advantages, and they are applicable to different scenarios.

5G: eMBB


The ITU (International Telecommunication Union) divides 5G networks into three major types. The first is eMBB, which stands for enhanced Mobile Broadband. As the name implies, eMMB is a 5G network that is specially designed for mobile devices such as mobile phones.

The eMBB will be the first of three to be commercially available. After all, the technology maturity of mobile phones is much higher than that of the latter two types.

5G: URLLC


The second is URLLC, short for Ultra Reliable Low Latency Communications. This type of 5G network will be mainly used in industrial applications and self-driving vehicles.

Google's Self-driving Car and URLLC

5G: MMTC


The third is MMTC which stands for Massive Machine Type Communications. MMTC is the type of 5G network that will be used in the IoT (Internet of Things) and IoE (Internet of Everything) scenarios. The strength of MMTC is to allow a large number of neighboring devices to enjoy a smooth communication connection at the same time.

Conclusion


5G is the current technology focus of the industry, so there are many related terms that circulate online. Although it is not necessary for users to understand the underlying principles, it is still necessary to understand the basic meaning of common terms.

What is Data Center Interconnect/Interconnection?

Data Center Interconnection means the implements of Data center Interconnect (DCI) technology. With the DCI technology advances, better and cheaper options have become available and this has created a lot of confusion. This is compounded by the fact that a lot of companies are trying to enter this market because there is a lot of money to be made. This article is written to straighten out some of the confusion.

According to the different applications, there are two parts of data center interconnections. The first is intra-Data Center Interconnect (intra-DCI) which means connections within the data center. It can be within one building or between data center buildings on a campus. Connections can be a few meters up to 10km. The second is inter-Data Center Interconnect (inter-DCI) which means connections between data centers from 10km up to 80km. Of course, connections can be much longer but most of the market activity for inter-DCI is focused on 10km to 80km. Longer connections are considered Metro or Long-haul. For reference, please see the table below.

DCI Distance Fiber Type Optics Technology Optical Transceivers
intra-DCI 300m MMF NRZ/PAM4 QSFP28 SR4
500m SMF QSFP28 PSM4
2km QSFP28 CWDM4
10km QSFP28 LR4
inter-DCI 10km SMF Cohernet QSFP28 4WDM-10
20km QSFP28 4WDM-20
30km to 40km QSFP28 4WDM-40
80km to 2000km CFP2-ACO

Intra-DCI


The big bottlenecks are in the intra-DCI and therefore, the highest volume of optical transceivers are sold here generating the most revenue, however, it is low margin revenue because there is so much competition. In this space, may of the connections are less than 300m and Multi-Mode Fiber (MMF) is frequently used. MMF is thicker, and components are cheaper because the tolerances are not as tight, but the light disperses as it bounces around in the thick cable. Therefore, 300m is the limit for many types of high speed transmission that use MMF. There is a data center transceiver with a transmission distance up to 100m over OM4 MMF for example.

100G QSFP28 SR4 for MMF up to 100m

In a data center, everything is connected to servers by routers and switches. Sometimes a data center can be one large building bigger than a football field and other times data centers are built on a campus of many buildings spanning many blocks. In the case of a campus, the fiber is brought to one hub and the connections are made there. Even if the building you want to connect to might be 200m away, the fiber runs to a hub, which can be more than 1km away, so this type of routing increases the fiber distance. Some of the distances between buildings can be 4km, requiring Single Mode Fiber (SMF), which has a much narrower core, making it more efficient, but also increasing the cost of all related components because the tolerances are tighter. Therefore, with data centers growing, so has the need for SMF as the connections get longer within the data center. With SMF you have the option to drive high bandwidth with coherent technology, and we'll see more of this in the future. Previously coherent was only used for longer distances, but with cost reductions and greater efficiency versus other solutions, coherent is now being used for shorter reaches in the data center.

500m is a new emerging market and because the distance is shorter, a new technology is emerging, and that is silicon photonics modulators. EMLs (Externally Modulated Lasers) perform modulation within the laser, but with silicon photonics, the modulator is outside the laser and it's a good solutions for distances of 500m. In an EML, the modulator is integrated into the same chip, but is outside the laser cavity, and hence is "external". For silicon photonics, the laser and modulator are on different chips and usually in different packages. Silicon photonics modulators are based on the CMOS manufacturing process that is high scale and low cost. A continuous wave laser with silicon photonic modulation is very good for 500m applications. EMLs are more suitable for longer reaches, such as 2-10km. Therefore, with data centers growing, so has the need for single mode fiber as the connections get longer within the data center. With SMF you have the option to drive high bandwidth with coherent technology, and we'll see more of this in the future. Previously coherent was only used for longer distances, but with cost reductions and greater efficiency versus other solutions, coherent is now being used for shorter reaches in the data center.

100GBASE-LR4 10km QSFP28 Optical Transceiver

100G QSFP28 LR4 for SMF up to 10km

Inter-DCI


Inter-DCI is typically between 10km and 80km, including 20km and 40km. Before we talk about data center connectivity, let's talk about why data centers are set up the way they are and why 80km is such an important connection distance. While it is true that a data center in New York might backup to tape in a data center in Oregon, this is considered regular long-haul traffic. Some data centers are geographically situated to serve an entire continent and others are focused on a specific metro area. Currently, the throughput bottleneck is in the metro and this is where data centers and connectivity are most needed.

100GE 4WDM-20 20km QSFP28 Optical Transceiver

100G QSFP28 4WDM-20 for SMF up to 20km

100GE 4WDM-40 40km QSFP28 Optical Transceiver

100G QSFP28 4WDM-40 for SMF up to 40km

Say you have a Fortune 100 retailer and they are running thousands of transactions per second. The farther away a data center is, the more the data is secure because the data center is so far away and separate from natural disasters, but with the increased distance there are more "in flight" transactions are at risk of being lost due to latency. Therefore, for online transactions there might be a primary data center that is central to retail locations and a secondary data center that is around 80km away. It's far enough away not to be affected by local power outages, tornadoes, etc, but close enough that there is only a few hundred milli-seconds of latency; therefore, in the worst case a small number of transactions would be at risk.

In another example of inter-DCI, as if a certain video is getting a lot of views, the video is not only kept in its central location, but copies of the video are pushed to metro data centers where access is quicker because it's stored closer to the user, and the traffic doesn't tie up long haul networks. Metro data centers can grow to a certain size until their sheer size becomes a liability with no additional scale advantage and thus they are broken up into clusters. Once again, to guard against natural disasters and power outages, data centers should be far away. Counterbalancing this, data centers need to have low latency communication between them, so they shouldn't be too far away. There is a compromise and the magic distance is 80km for a secondary data center, so you'll hear about 80km data center interconnect a lot.

It used to be that on-off keying could provide sufficient bandwidth between data centers, but now with 4K video and metro bottlenecks, coherent transmission is being used for shorter and shorter distances. Coherent is likely to take over the 10km DCI market. It has already taken over the 80km market but it might take time before coherent comes to 2km. The typical data center bottlenecks are 500m, 2km, and 80km. As coherent moves to shorter distances, this is where the confusion comes.

The optical transceiver modules that were only used within the data center are gaining reach, and they're running up against coherent solutions that were formerly only used for long distances. Due to the increasing bandwidth and decreasing cost, coherent is being pulled closer into the data center.

The other thing to think about is installing fiber between data centers. Hopefully this is already done, because once you dig, it's a fixed cost, so you put down as many fibers as you can. Digging just for installing fiber is extremely expensive. In France when they lay fiber, they use another economic driver. Whenever you put in train tracks, you put in fiber at the same time, even if it is not needed. It's almost for free because they are digging anyway. Fibers are leased to data centers one at a time; therefore, data centers try to get as much bandwidth as possible onto each fiber (this is also a major theme in the industry). You might ask, why not own your own fiber? You need to have a lot of content to own your own fiber. The cost is prohibitive. In order to make the fiber network function, all the nodes need to use the same specification and this is hard. Therefore, carriers are usually the ones to install the full infrastructure.

A Guide to the Interfaces of Optical Transceiver Modules

In today's optical communications market, there are a variety of transceiver modules with various types of interfaces. Because different types of cables/connectors/adapters are required for different interfaces, we need to pay more attention when selecting the relevant assemblies. This article will give you a detailed introduction to the mainstream transceiver module interfaces on the market, so that everyone has a clearer understanding of the transceiver modules.

First of all, we use the following table to list all transceiver modules' interfaces.

Form Factor Transmission Mode Interface Example
QSFP-DD Parallel MPO 200G QSFP-DD SR8/PSM8
QSFP-DD Multiplexing Dual CS 200G QSFP-DD CWDM8
QSFP28 Parallel MPO 100G QSFP28 SR4/PSM4
QSFP28 Multiplexing Duplex LC 100G QSFP-DD LR4/CLR4/CWDM4/ER4
QSFP+ Parallel MPO 40G QSFP+ SR4/PSM4
QSFP+ Multiplexing Duplex LC 40G QSFP+ LR4
SFP28 Dual Fiber Duplex LC 25G SFP28 SR/LR
SFP28 Single Fiber Bidirectional Simplex LC 25G SFP28 BiDi
SFP+ Dual Fiber Duplex LC SFP+ 10GBASE-SR/LR
SFP+ Single Fiber Bidirectional Simplex LC/SC SFP+ BiDi
SFP+ 2-channel Bidirectional Dual LC SFP+ 2-channel BiDi
SFP+ Electrical Copper Cable RJ-45 SFP+ 10GBASE-T
SFP Dual Fiber Duplex LC SFP 1000BASE-SX/LX
SFP Single Fiber Bidirectional Simplex LC/SC SFP BiDi
SFP 2-channel Bidirectional Dual LC SFP 2-channel BiDi (CSFP)
SFP Electrical Copper Cable RJ-45 SFP 1000BASE-T
CXP Parallel MPO 120G CXP SR10
CFP Parallel MPO 100G CFP SR10
CFP Multiplexing Duplex LC 100G CFP LR4/ER4
CFP2 Parallel MPO 100G CFP SR10
CFP2 Multiplexing Duplex LC 100G CFP2 LR4/ER4
CFP4 Parallel MPO 100G CFP4 SR4
CFP4 Multiplexing Duplex LC 100G CFP4 LR4/ER4

As the table shows, although there are more than a dozen types of transceiver modules, there are only a few types of interfaces. These types of optical interfaces are LC, SC, MPO, and CS. And there are also electrical copper transceiver modules using the RJ-45 interface. Among these interfaces, the LC interface can be divided into duplex and simplex, and there are dual-simplex LC interface (such as CSFP). For BiDi optical transceivers, there are also simplex SC interface, in addition to the simplex LC. We will introduce each of these interfaces one by one, according to the transmission modes of the transceiver modules.

LC/SC


As we konw, a transceiver module consist of a transmiter and a receiver. This means that the transmission has two directions. For the common single-channel optical transceivers, such as SFP28, SFP+, and SFP, the transmitting terminal is connected to one optical fiber and the receiving terminal is also connected to one optical fiber. That's why the common optical transceivers are called dual-fiber transceiver generally. The dual-fiber transceiver has a duplex LC interface connected to a duplex LC patch cable. (The XENPAK, X2, and GBIC dual-fiber transceivers, not listed in the table, have a duplex SC interface connected to a duplex SC patch cable.)

Standard Transmission Mode of Transceiver Modules

Standard Dual-Fiber Optical Transceiver Modules

The single-fiber bidirectional transmission mode is called BiDi for short. The BiDi signals in both directions are combined in a single fiber. The bidirectional transmission means that the light is directional and will not interference each other. The BiDi optical transceiver, such as BiDi SFP+ and BiDi SFP, have a simplex LC or SC interface connected to a simplex LC or SC patch cable. And for high-density BiDi transmission networks, there are 2-channel BiDi SFP+/SFP (CSFP+/CSFP) optical transceivers using dual simplex LC interface.

Single-Fiber Bidirectional Transmission Mode of Transceiver Modules

Single-Fiber BiDi Optical Transceiver Modules

MPO


For multi-channel optical transceivers, such as 4-channel QSFP+, 4-channel QSFP28, and 8-channel QSFP-DD, there are several Tx and several Rx. Some of them (such as 100G QSFP28 SR4 and 100G QSFP28 PSM4) have MPO interfaces, that is, multi-fiber pull on/off, using multiple optical fibers for the parallel transmission shown as the figure below.

Multi-Fiber Parallel Transmission Mode of Transceiver Modules

Multi-Fiber MPO Optical Transceiver Modules

There are also dual-fiber 4-channel optical transceivers using the multiplexing transmission mode, that is, multiple Tx multiplexing and Rx demultiplexing. These optical transceivers, such as 40G QSFP+ LR4 and 100G QSFP28 CWDM4, use two optical fibers for long-distance transmission, saving more optical fiber resources than using multi-core optical fibers. Like the common single-channel optical transceiver, the dual-fiber 4-channel optical transceiver also has a duplex LC interface connected to a duplex LC patch cable.

CS


The QSFP-DD MSA specification defines an 8-channel module, cage and connector system. The cage and connector system provides backward compatibility to the 4-channel QSFP28 modules. Doubling the number of duplex optical links with the QSFP-DD specification requires a new smaller optical interconnect to fit in the same physical cage form factor. For the eight-channel QSFP-DD optical transceivers using the multiplexing transmission mode, a new type of optical interface called dual CS is used to replace the duplex LC. The dual CS interface is connected to the CS connector, a miniature single-position plug which is characterized by duo cylindrical, springloaded butting ferrule(s) of a 1.25 mm typical diameter, and a push-pull coupling mechanism. The CS connector provides the characteristics and simplicity of the duplex LC connector into a smaller footprint to allow 2 pairs of CS connectors to fit within the physical constraints of the QSFP-DD form factor.

CS connector

RJ-45


The RJ-45 interface is used in copper transceiver modules, such as 10G copper SFP+, 1G copper SFP and 100M copper SFP. The copper SFP+ transceivers transmit electrical signals over Category 6a or Category 7 copper cables with RJ-45 connectors, while the copper SFP transceivers transmit electrical signals over Category 5 or Category 5e copper cables with RJ-45 connectors.
