SYNOXX 1.25G SFP BiDi Transceiver Pair EB3512-3D/EB5312-3D LC 3km

The SYNOXX EB3512-3D/EB5312-3D is a matched pair of 1.25G SFP BiDi (bidirectional) transceivers engineered for Gigabit Ethernet and Fiber Channel connectivity over a single strand of OS2 single-mode fiber up to 3km. Using wavelength-division multiplexing (WDM), each transceiver simultaneously transmits and receives on separate wavelengths — EB3512-3D at TX1310nm/RX1550nm and EB5312-3D at TX1550nm/RX1310nm — enabling a full-duplex 1.25Gbps link over one fiber strand instead of two. This halves the fiber count for every link, making the EB3512-3D/EB5312-3D pair the standard solution for environments where fiber capacity is constrained or fiber installation costs must be reduced.

Compliant with SFP MSA and SFF-8472 standards, both transceivers support full Digital Diagnostic Monitoring (DDM) for real-time visibility into temperature, voltage, TX/RX optical power, and bias current. LC simplex connectors, 3.3V operation, and hot-pluggable SFP form factor ensure compatibility across all SFP-equipped enterprise switches, routers, and Fiber Channel HBAs. Always install the pair together: EB3512-3D at one end and EB5312-3D at the opposite end of the same fiber strand — mixing wavelength-mismatched transceivers will prevent the link from establishing.

IC Certified by Industry Canada (ISED), the EB3512-3D/EB5312-3D pair meets regulatory requirements for commercial deployment.
