SFP 1.25G Tx1310/Rx1550 20Km LC Transceiver

SFP 1.25G Tx1310/Rx1550 20Km LC Transceiver is a product of SFP BIDI optical module series. BIDI optical module is an optical module using WDM (wavelength division multiplexing) bidirectional transmission technology, which realizes bidirectional transmission in the optical channel on one optical fiber at the same time. The SFP 1.25 G 1310nm 20km LC Transceiver optical module has only one port, and the signal is transmitted and received on one optical cable through the integrated bidirectional coupler. Therefore, it must be paired with the SFP 1.25G Tx1550/Rx1310 20Km LC Transceiver. BIDI SFP+ optical modules reduce the number of ports on the fiber patch cord panel, reduce the footprint of the tray dedicated to fiber management, and reduce the number of fiber optic cables that need to be used.

Tx Disable has an LVTTL logic high-level input that can disable the optical output, and the system can also disable the module through I²C. The Tx Fault is supplied to signal laser deterioration. The LOS output is used to show the loss of an optical signal input to the receiver or the state of the link with the partner. I²C register access can also be used to obtain LOS (or Link)/Disable/Fault information for the system.
