Bidirectional SFP transceiver delivering 125 or 155 Mbps over 20 km single-mode fibre with Tx 1550 nm and Rx 1310 nm wavelengths
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.
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.
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.

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.
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.
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.
