SFP-9421 1.25Gbps Single-mode BIDI(WDM) SFP Transceiver, 40km, TX 1310nm / RX 1550nm

The LevelOne SFP-9421 is a high performance, costeffective SFP transceiver. It provides up to 1.25 Gbps bi-directional data transfer rate at distances up to 40km on a single fiber core. These bi-directional SFP Transceivers allow data transfer in either direction through a single optical fiber by employing separate wavelengths travelling in either direction.The SFP-9421 transmits using a wavelength of 1310nm and receives using a wavelength of 1550nm. When coupled with the LevelOne SFP-9431 transceiver which transmits at and receives at the opposite rates (1550nm TX and 1310nm RX) you get bi-direction data communication on a single fiber core. The LevelOne SFP-9421 is, therefore, an optimal solution for a high number of fiber lengths in only a few fibers.
