Description
The Sopto SPT-PB541G-LXXD + SPT-PB451G-LXXD BiDi transceiver set enables 1.25Gbps full-duplex communication over a single strand of single-mode fiber, reducing fiber deployment costs. Each module operates on complementary wavelengths — 1550 nm TX / 1490 nm RX for the PB541G-LXXD and 1490 nm TX / 1550 nm RX for the PB451G-LXXD.
Designed for Gigabit Ethernet and 1G Fibre Channel applications, these modules comply with IEEE 802.3z 1000BASE-BX, SFP MSA, and SFF-8472 standards. They feature digital diagnostics monitoring (DDM), enabling operators to monitor key parameters like optical power, temperature, and voltage in real time.
With LC simplex connectors, a hot-pluggable form factor, and low power consumption (<1 W), the modules are easy to deploy and maintain. Their availability in commercial (0–70 °C) and industrial (–40–85 °C) grades makes them a robust solution for FTTH access networks, enterprise backbones, and campus deployments.
