Description
This Finisar SFP transceiver module employs Wavelength Division Multiplexing (WDM) technology, enabling bidirectional communication over a single strand of single-mode fiber. This offers significant advantages in terms of fiber utilization and infrastructure cost savings. Operating at 1.25Gb/s with a 20km reach, this transceiver is well-suited for applications such as Gigabit Ethernet and Fibre Channel in enterprise and service provider networks. The specific operating wavelength of 1562.23nm is designed to work in conjunction with other WDM transceivers on the same fiber. This module ensures reliable data transmission for moderate-distance SMF links within a WDM system.
