What are the newly launched optical module products in the market?

1. 400G QSFP-DD coherent pluggable module

400G QSFP-DD Coherent Pluggable Module

The flexibility of pluggable interfaces has always been a major factor in the success of optical transmission over Ethernet, and coherent optical modules have played an important role in modern long-haul fiber optic communication links, often focusing on maximum performance and using custom-built modules on large fixed modules. Optical Devices and ASICs. The 400G ER1 QSFP-DD coherent pluggable optical module provides client multiplexing, interoperability based on OIF and OpenZR+ protocols, and the transmission distance on unamplified links can reach 40 kilometers. It will be used for access, campus and 5G networks.

2. 50G SFP56 FR/LR series optical modules

Applied to 5G fronthaul, dual-carrier is an important product direction in improving overall network capabilities. At the same time, dual-carrier technology is also highly in line with domestic development plans and meets the needs of operators for network construction. The fronthaul under dual carrier aggregation is mainly 2x25G, but with the coordinated advancement of technology and industry chain, the demand for single-channel 50G optical modules is about to mature, and 50G SFP56 FR/LR series optical modules for wireless network applications are launched. The 50G SFP56 FR and 50G SFP56 LR optical modules meet the IEEE 802.3cd standard and are all packaged in SFP56, allowing users to flexibly choose 2x25G NRZ and 1x50G PAM4 electrical signal modulation, optical signal is 50G PAM4 modulation, suitable for industrial temperature (-40°C) C to +85°C), supporting transmission distances of 2km and 10km, respectively.

3. 12G SDI optical module

As remote teaching, telemedicine, sports events and other live broadcasts have higher and higher requirements for video picture quality and longer transmission distances, 12G SDI optical modules can just meet the needs of high-definition video transmission. 12G SDI is a solution for 4K ultra-clear video optical transmission. The difference from ordinary optical modules lies in the encoding method of the video data stream and the telecommunication data. In addition, a "pathological code test" of the video standard is required to complete the transmission and transmission of data signals to ensure the clarity and stability of the video. The main principle is that 12G SDI can integrate four 3G-SDI signal lines into one to transmit 4K audio and video.
