BIDI SFP transceiver for 100BASE-BX links

This bidirectional SFP module operates at 125 Mbps for Fast Ethernet 100BASE-BX10 and at 155 Mbps for SONET OC-3 or SDH STM-1 traffic. It transmits at 1550 nm and receives at 1310 nm over single-mode fibre, reaching up to 20 km. The module complies with IEEE 802.3 ah and INF-8074i MSA standards and is rated for commercial temperatures from 0 to 70 °C.

Fits a single SFP slot with simplex LC cabling

The transceiver plugs into any standard SFP port that supports the 100BASE-BX interface and accepts a simplex LC connector, so only one fibre strand is required. It draws power from a single 3.3 V supply provided by the host and uses the 2-wire SFF-8472 interface for diagnostics. TAA compliance and RoHS, REACH, CE, FCC, TUV and UL certifications simplify procurement for regulated projects.

Steady throughput over long single-mode runs

Because the link budget is engineered for 20 km of single-mode fibre, the module maintains its 125/155 Mbps data rate continuously without the short-burst limitations seen in some lower-reach optics. The FP laser transmitter and integrated diagnostic monitoring keep optical power stable across the full 0–70 °C operating range, so sustained traffic flows remain reliable in campus, metro or industrial deployments.

Questions about this item

What is the maximum link distance this 125/155Mbps BIDI SFP transceiver supports over single-mode fiber?

This transceiver reaches 20km over single-mode fiber at 125Mbps for Fast Ethernet 100BASE-BX10 or 155Mbps for SONET OC-3/SDH STM-1 applications.

How much power does the module draw and what is its operating temperature range when running continuously?

It operates from a single +3.3V supply across a commercial temperature range of 0 to 70°C, with a simplex LC connector and 1550nm FP laser transmitter.

Which host equipment brand and model must I already own so the supplier can program the correct coding into this transceiver?

You need to provide the exact brand and model of your switch or router before ordering so the module can be coded for compatibility with your host equipment.
