In theory, interfaces of the same standard type can be connected, but attention should be paid to the optical power range and transmission distance during actual use. The main factors affecting the docking of optical modules are shown in the table below. But sometimes it will cause some problems due to the use of non-standard, so what do we need to do to avoid the problems caused by the non-standard use? The following ETU-LINK will explain. With the wide range of optical modules, more and more customers have begun to pay attention to the stability and reliability of the modules themselves. There are three kinds of popular optical modules on the market now: original optical modules, second-hand optical modules and compatible optical. The optical fiber transceiver must have a cap, and cover the cap when not in use to avoid the contamination of the optical fiber transceiver and the secondary contamination of the optical port of the optical module. 6T optical modules, 800GE optical modules, 400GE optical modules, 100GE optical modules, 40GE optical modules, 25GE optical modules, 10GE optical modules, GE optical modules, FE optical modules, and so. What are the key performance indicators of optical modules? How to Measure Optical Module Performance Indicators? We can understand the performance indicators of an optical module from the following aspects.
