The external accessories are composed of a shell, a base, a PCBA, a pull ring, a buckle, a unlocking piece, and a rubber plug. The color identifies the parameter type of the module. The core of the sinking type unlocking is to pull the ring pulling process, driving the optical module shell triangle locking device sinking, and SFP cage detached to achieve unlocking, Figure 2 is the ring is not pulled up, in the locked state of the photo: Figure 2 Sinking unlocking scheme -. The characteristic of a single-fiber bidirectional optical module is that it can realize signal transmission in two directions simultaneously on a single optical fiber. Different wavelength combinations and pull-ring colors correspond to different transmission specifications. Each SFP module operates at a specific wavelength, and to. The pull ring of the optical module adopts the function of using different colors Their main function is to identify the type, wavelength, and function, allowing technicians to quickly determine its type and use case without removing the optical module.
