A 1.25G SFP (Small Form-factor Pluggable) module, BIDI (Bi-directional), operates at 1310nm wavelength and supports distances up to 3km using an SC port. This module is designed for bi-directional data transmission over a single strand of fiber optic cable, where both transmit and receive signals are managed. It’s suitable for applications needing cost-effective communication over moderate distances, commonly used in telecommunications and enterprise networks for efficient data transmission.
