BIDI SFP Transceiver for 40 km Links

This bidirectional SFP transceiver operates at 125/155 Mbps with a Tx wavelength of 1310 nm and Rx wavelength of 1550 nm. It connects via a simplex LC connector over single-mode fibre for distances up to 40 km. The module is hot-pluggable and compliant with the INF-8074i SFP MSA, making it suitable for Fast Ethernet 100BASE-BX10 and SONET OC-3 or SDH STM-1 applications. It requires host-equipment coding confirmation before deployment.

Thermals, Noise and Power Draw

The transceiver draws power from a single 3.3 V supply and is rated for commercial temperature operation. As a passive optical module with no moving parts, it produces no audible noise and adds minimal thermal load to the host chassis. Power consumption stays within the SFP MSA envelope, allowing dense port population without special cooling. The 2-wire management interface compliant with SFF-8472 enables real-time monitoring of temperature, voltage and optical levels.

Build Integration and Compatibility

The module fits any standard SFP cage and uses a simplex LC patch cord, freeing a second fibre strand for other links. It is coded for wide compatibility with Cisco, Juniper and other open switches, though the exact coding must be specified at order time. TAA compliance and RoHS certification support regulated procurement. RoHS compliance and Taiwan manufacture suit regulated procurement. Buyers needing longer reach, multimode fibre or dual-fibre interfaces should select a different model from the same series.

Questions about this item

How do I install the SFP module and avoid the common mistake with the simplex LC connector?

Insert the module into an SFP port until it clicks, then connect the single-mode fiber to the simplex LC port matching the Tx 1310 nm and Rx 1550 nm markings; the frequent error is reversing the Tx and Rx fibers.

What maintenance or replacement will the 1310 nm FP laser transmitter need over time?

The 1310 nm FP laser and the 2-wire SFF-8472 diagnostic interface should be monitored for rising bias current or falling optical power; plan replacement when thresholds indicate end of life.

At what distance limit does signal loss appear first on a 40 km single-mode fiber link?

The link is rated for 40 km over single-mode fiber; attenuation or dispersion beyond that distance will cause errors first.
