Small Form-factor Pluggable, 3.125G DWDM, 70KM, Channel Number :21, Center Frequency(THz) : 192.1

The 3.125 Gbps, 70 km, DWDM SFP transceiver module plugs into ADTRAN equipment designed to accept Small Form-factor Pluggables (SFPs). The SFP converts a 3.125 Gbps serial electrical data stream to a 3.125 Gbps optical output signal and a 3.125 Gbps optical input signal to a
3.125 Gb/s serial electrical data streams when installed into an appropriate host unit.

Designed for Ethernet LAN and WAN multi-rate applications at up to 70 km
links over single-mode fiber.
