Frequently Asked Questions (FAQ)
What is an SFP BIDI transceiver module?
An SFP BIDI (Bi-Directional) transceiver is a compact optical module that uses Wavelength Division Multiplexing (WDM) technology to transmit and receive data over a single strand of fiber, effectively doubling the capacity of your existing fiber infrastructure.
Why do BIDI transceivers need to be used in pairs?
BIDI transceivers must be deployed in matched pairs (e.g., T13/R15 paired with T15/R13) because they transmit and receive at complementary wavelengths. One end transmits at wavelength A and receives at wavelength B, while the other end must transmit at wavelength B and receive at wavelength A.
What fiber connector type is compatible with these modules?
All the 1.25G SFP BIDI modules listed in the ordering table are equipped with a simplex LC connector, designed for single-mode fiber (SMF) connections.
What is the maximum transmission distance supported?
Depending on the specific model, these SFP BIDI modules support transmission distances starting from 3KM for standard short-reach setups, up to 160KM for ultra-long-haul network applications.
Are these SFP BIDI transceivers hot-pluggable?
Yes, these modules support hot-plugging, which allows network administrators to install or replace the modules in switches or routers without powering down the host device, ensuring continuous network uptime.
