BIDI SFP Module for 80 km Links

This bidirectional SFP transceiver delivers 125/155 Mbps over a single-mode fibre strand using Tx 1550 nm and Rx 1490 nm wavelengths. It targets network engineers extending 100Base-BX-D, SDH STM-1 L 1.3 or SONET OC-3 LR-3 services to 80 km. The module fits standard SFP cages and operates on a single 3.3 V supply.

Practical Limits of the SFP MSA Interface

The SFP MSA footprint restricts the module to the 100 Mbps class; it cannot serve 1 Gbps or 10 Gbps line rates. Commercial-temperature rating confines deployment to controlled indoor environments. Link budget is calibrated for 80 km on standard single-mode fibre; longer spans or higher loss budgets require a different module. Host equipment must accept the specific vendor coding programmed at order time.

80 km Reach on Single-Mode Fibre

The 80 km transmission distance over single-mode fibre is the decisive specification for this part. Buyers needing shorter 20, 40 or 60 km reaches or longer 120 km spans should select another model from the same family. The fixed Tx 1550 nm / Rx 1490 nm wavelength pair also means the companion module must use the opposite pairing for the link to function.

Questions about this item

Which distance variant should I pick for my link?

Choose the 80 km version when your single-mode fiber run is up to 80 km; shorter reaches such as 20 km, 40 km or 60 km use different part numbers.

What does the 125/155 Mbps rate mean once the module is installed?

It supports bi-directional links up to 155 Mb/s, compatible with 100Base-BX-D Ethernet, SDH STM-1 L 1.3 and SONET OC-3 LR-3.

Which interface standard does the module follow and what does it cap in practice?

It complies with SFP MSA and SFF-8472, uses a simplex LC connector, runs on 3.3 V and is hot-pluggable.
