A transceiver is an interconnect that links Ethernet ports to copper and optical fiber networks. Switch transceiver is a high performing linking device that is designed to deliver data connectivity with low insertion loss. This transceiver is made to comply with different Ethernet standards and is usable with Ethernet, Fast Ethernet, SDH/SONET and Gigabit Ethernet applications. A switch transceiver can belong to SFP, SFP+, QSFP, XFP and other tunable form factor types and is suitable for both multi-mode and single mode fiber. Switch transceiver finds its best use in data center networks, inter-location networks and in-premise networks and is widely used for datacom and telecommunications. This transceiver is functional at industrial temperature range and accepts wavelengths ranging from 850nm to 1550nm to deliver data connectivity ranging from 300m to 120km. Cozlink produces switch transceiver and patch cords, pigtails, splitters etc. compatible with it.
