Syrotech GOXS-BI4503-120D Syrotech GOXS-BI5403-120D | Single Fiber SFP Bi-Directional Module (Combo) 120Km

The Syrotech GOXS-BI4503-120D and Syrotech GOXS-BI5403-120D are 1.25G bidirectional SFP modules designed for ultra-long-range fiber optic communication, supporting up to 120 kilometers of transmission distance. These modules enable both transmit and receive data functions over a single fiber, optimizing infrastructure by reducing cable requirements. Ideal for telecom, enterprise, and long-distance network applications, these modules offer reliable, high-performance connectivity with minimal signal degradation over extended distances. The modules are compatible with various networking devices and come with SC or LC connectors for easy integration.

The SFP-BIDI transceivers are high performance, cost effective modules supporting dual data-rate of
125Mbps/155Mbps and 120km 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.
