25G SFP28 CWDM Optical Transceivers Series
Quick Details
25G SFP28 CWDM transceiver modules enable connectivity between the existing network equipment and course wavelength division multiplexing (CWDM) Mux/DeMux. Mux/demux devices work together to carry out the process of transmission and reception of data in the communication system. A multiplexer is a combinational circuit. Its distinct feature is that it provides a single output but accepts multiple data inputs. Unlike it, a demultiplexer takes a single input but can direct it through multiple outputs.
All of VCHUNG’s 25G SFP28 CWDM transceiver modules are compliant with IEEE802.3by and SFF-8472 standards and compatible with Huawei, H3C, Cisco, Alcatel-Lucent, Juniper, and various other equipment.
