WDM SFP 155Mb

The WDM small form-factor pluggable (SFP) is a compact optical transceiver, module used in optical communications for both telecommunication and data bidirectional communications applications. It interfaces a network device mother board (for a switch, router or similar device) to a fiber optic or unshielded twisted pair networking cable. It is a popular industry format supported by several fiber optic component vendors.
