Optical modules in the application must have standardized operating methods, any irregular action may cause hidden damage or permanent failure.The main reason for the failure of the optical module is the main reason for the failure of the optical module ESD damage caused by the deterioration of the performance of the optical module, as well as the optical port contamination and damage caused by th

As data center network traffic continues to grow, there is a need to provide higher bandwidth and higher density optical interconnect solutions. 400G optical modules, as the core product for data centers, feature high bandwidth, low latency, and high reliability, and are the key to realizing high-speed interconnections between equipment within the data center. Among many 400G optical modules, 400G

400G SR4.2 and 100G SRBD optical modules enable the transition to 400G rates without changing existing multimode fiber. Not only can they save fiber resources, they can also simplify the process of migrating to higher speeds and protect existing fiber infrastructure. In this article, State Road introduces you to 400G SR4.2 and 100G SRBD optical modules. 400G SR4.2 Optical Module Introduction4

Currently, the mainstream 100G optical modules are QSFP28 optical modules, which include QSFP28-SR4, QSFP28-LR4, QSFP28-PSM4, and QSFP28-CWDM4.Figure:100G QSFP28 ZR4 80KMQSFP28 CWDM4 vs QSFP28 LR4The QSFP28 CWDM4 standard is mainly for the deployment of 100G links within 2km in data centers, and the interface of QSFP28 CWDM4 optical modules conforms to the duplex single-mode 2km 100G optical inter

To upgrade GPON to XGPON1 or XGSPON, the mainstream solution in the market is the external combiner solution. This program increases XGPON1/XGSPON boards, and then through the external combiner, the signals of GPON and XGPON1/XGSPON are combined in the form of WDM, and transmitted to the remote users. The principle of this program is relatively simple, but there are many drawbacks such as long upg
