      Ten common faults and solutions of optical fiber transceivers

      Fiber optic transceivers are generally used in the actual network environment where Ethernet cables cannot cover and must use optical fibers to extend the transmission distance. They are usually located at the access layer of broadband metropolitan area networks, and are widely used in various mo...

      How to judge whether there is a problem with the fiber optic transceiver?

      In general, the luminous power of the optical fiber transceiver or optical module is as follows: multimode is between 10db and -18db; single mode is 20km between -8db and -15db; and single mode is 60km is between -5db and -12db between. But if the luminous power of the fiber optic transceiver app...
