The White Paper of 5g Carrier Optical Module Points Out That the 25gb / S Wavelength Tunable Optical

The imt-2020 (5g) promotion group released the white paper 5g optical module, which described the application scenario and development status of 5g optical module, the technical scheme of key optical modules for forward transmission and middle transmission, the analysis of the industrialization level of optical module and core photoelectric chip, the evaluation of the industrialization capacity of optical module, and the development suggestions of technology industry, To accelerate the healthy and orderly development of 5g bearing optical module industry and strongly support the upcoming large-scale deployment of 5g.

The industry has carried out extensive research on optical modules suitable for 5g carrying different application scenarios. At present, there are a variety of technical schemes and product specifications. Too many schemes and specifications are likely to lead to market fragmentation and waste of resources such as upstream and downstream R & D, manufacturing, operation and maintenance. The technical scheme of 5g bearing optical module needs to focus on convergence. According to the application scenario, technology maturity, cost and other factors, the white paper focuses on key forward optical modules such as 25gb / s dual fiber bidirectional, 25gb / s single fiber bidirectional, 25gb / s wavelength tunable, 100GB / s and 200GB / s single fiber bidirectional, as well as 25gb / s dual fiber bidirectional, 50GB / s single fiber bidirectional / dual fiber bidirectional, 100GB / S 400gb / s gray light The technical schemes of key optical modules in coherent and incoherent 50GB / s and 100GB / s color light are analyzed and comprehensively evaluated.

At present, the 25gb / s wavelength tunable optical module for 5g front transmission is in the research stage, the 25gb / s bidi optical module is in the sample stage, and other types of 25gb / s optical modules are in the mature stage. The 100GB / s bidi optical module, 200GB / s bidi optical module and 100GB / s 4wdm optical module with higher rate for front transmission are basically mature or mature. The 50GB / s pam4 bidi 40km optical module and 400gb / s direct harmonic coherent optical module for 5g medium return are currently in the research stage, and other types of optical modules have been basically mature. At present, domestic manufacturers can provide most products at the optical module level, and their R & D level is also close to that of foreign leading enterprises. However, the core photoelectric chips with 25G baud rate and above are still in the research, sample or blank stage. The innovation and development needs the pull of downstream equipment manufacturers and the improvement of industrial ecology.
