5G motivates the edge computing progress. Higher rate and higher density optical transceivers will be required. Edge computing is the leading-edge technology for the next-generation data center. In the current period, edge computing is in the period of practice. It is important that how to develop edge computing and how to meet the needs of edge computing. On Jun. 25, 2019, the OCP China Day hosted in Beijing, China by one OCP Platinum member, Inspur. The distinguished guests from Microsoft, Facebook, LinkedIn, Baidu, Tencent, and Inspur attended the conference. They share vital topics such as artificial intelligence, edge computing, and SONiC about various leading-edge technologies here. Among these topics, edge computing has been frequently mentioned, here we will discuss the development of 5G and edge computing.

The demand for the 100G optical transceiver by the 5G network is very urgent. At present, there are many kinds of mature 100G optical transceivers in the market such as 100G QSFP28 optical transceivers and 100G CFP-DCO optical transceivers provided by Gigalight. This article will introduce the optical transceivers can be provided by Gigalight for 5G fronthaul, midhual and backhaul, especially, 25G BiDi Fronthaul Solution, 100G QSFP28/200G QSFP56 Midhaul/Backhaul Solution. First of all, let’s see the demand for optical transceivers by 5G. Optical Transceivers for 5G Fronthaul( I-temp) Product Name Wavelength Reach Optical Interface Fiber Type Power Consumption 100G QSFP28 SR4 850nm 100m MPO-12 MMF ＜2.5w 100G QSFP28 4WDM-10 LWDM 10km Dual LC SMF ＜3.5w 25G SFP28 SR 850nm 100m Dual LC MMF ＜1w 25G SFP28 LR 1310nm 10km Dual LC SMF ＜1.5w 25G SFP28 ER 1310nm 40km Dual LC SMF ＜2.5w 25G BiDi SFP...

The 5G standardization process is complex and highly innovative. 5G standards are developed in the 3rd Generation Partnership Project (3GPP), ITU Radiocommunication Sector (ITU-R), ITU Telecommunication Standardization Sector (ITU- T), the Internet Engineering Task Force (IETF) and IEEE. Here we focus on activities within 3GPP. 1.3GPP 5G will expand the LTE platform for new services while improving its efficiency to meet the mobile broadband demand. 2.3GPP 5G is not only a new radio (NR) interface but a full system, integrating LTE and NR radio access technologies with a 5G Core Network 3. Initially, some of the use cases will be fulfilled by LTE, but the aim is to eventually fulfill all the requirements with NR 4. From Release 15 onwards, the 3GPP specifications (LTE, NR and Core Network) will be marked “5G” 5.5G expands offerings by specializing radio and network capabilities (vertical sectors): – Enhanced Mobile Broadband – Massive Internet of Things – Ultra-Re...

5G is expected to be implemented in the following years. To have this 5G network realized, optical communication will be the cornerstone technology independent of various fronthaul options. The demand for high-rate optical transceivers will significantly increase because higher base-station density is required for the 5G network. Although it is still not clearly determined which fronthaul architecture will be used in the 5G network, it is apparent that the network would employ both grey and color optics for 25Gbps based on 5G bandwidth requirement. Grey and Color Optics The light in WDM systems is carried over different wavelengths compliant with specific standards. To distinguish wavelengths in different systems, the wavelengths in WDM systems are called colored light whereas the wavelengths in common optical systems are called grey light. Grey light is within a certain wavelength range and does not have a standard wavelength, for example, the light at client-s...

We are now starting to see commercial 5G networks going live. Previous generations were focused on consumer and personal communications but now 5G will serve consumers, enterprises and take the internet of things to the next level, where superior connectivity is a prerequisite. Initially, 5G will be a capacity enhancer in metropolitan areas and enhanced mobile broadband and fixed wireless access will be ways for operators to address explosive traffic growth. According to LightCounting, 5G will drive significant growth in the global market for optical transceivers since 2019, especially in China. At the same time, the demand for low-speed optical devices below 10G will gradually decrease and increase in the demand for transceivers of 25G, 50G, and 100G. The change of optical transceiver demand is driven by 5G revolution. RAN architecture of the 5G system will realize the separation of CU and DU, which determines that 5G wireless network will include fronthaul, midhaul and ba...

Since 2010, the global demand for optical devices has been increasing year by year. In 2014, the demand for optical devices reached a peak. Although the demand for optical transceivers declined after that, in 2019, with the arrival of the 5G era, the global demand for optical transceivers re-entered the rapidly growing channel. Especially in the Chinese market, the demand for wireless optical devices is very large. The application of 25G optical transceiver in 5G fronthaul is a basic consensus. Both operators and equipment manufacturers will consider 25G optical transceiver as a mainstream transceiver in the early stage of 5G construction. Meanwhile, for 100G optical transceivers, the equipment manufacturer has an optimistic expectation for the growth rate of 5G optical transceivers. With the gradual arrival of the global 5G era, this revolution has also brought about an explosion of the market demand for 5G optical transceivers and optical devices. What changes will the...
