Syrotech GOXS-BI3503-40D Syrotech GOXS-BI5303-40D | Single Fiber SFP Bi-Directional Module (Combo) 40Km

The Syrotech GOXS-BI3503-40D and GOXS-BI5303-40D are 1.25G bidirectional SFP modules designed for long-range fiber optic communication with a 40KM reach. These combo modules enable data transmission over a single fiber, supporting both transmit and receive functions, which reduces infrastructure complexity and cabling requirements. Ideal for telecom, data center, and enterprise network applications, the modules provide high-speed, reliable connectivity with minimal signal degradation over extended distances. They are equipped with SC connectors for secure and easy installation and are fully compliant with industry standards, ensuring compatibility with a wide range of networking equipment.

The SFP-BIDI transceivers are high performance, cost effective modules supporting dual data-rate of
125Mbps/155Mbps and 40km transmission distance with SMF.
The transceiver consists of three sections: a FP laser transmitter, a PIN photodiode integrated with a
trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety
requirements.
The transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. For further
information, please refer to SFP MSA.
