• BiDi technology transmits and receives on different wavelengths over a single fibre strand, halving fibre infrastructure requirements compared to duplex transceivers while maintaining full gigabit throughput
• 1000BASE-BX40-D compliance ensures interoperability with MSA-compliant SFP hosts; the -D variant transmits at 1490nm and receives at 1310nm, requiring pairing with a complementary -U transceiver (such as FN-TRAN-SFP-1BU40) at the opposite end
• Industrial temperature rating from -40°C to 85°C supports deployment in outdoor cabinets, factory automation, transportation infrastructure, and other harsh environments where commercial-grade optics cannot operate
• Digital optical monitoring provides real-time access to transmit power, receive power, supply voltage, laser bias current, and module temperature for proactive fault detection and link budget analysis
• Hot-swappable SFP form factor with single LC simplex connector simplifies installation, reduces cabling complexity, and allows field replacement without powering down the host system
• 40km reach over ITU-T G.652 single-mode fibre enables metro aggregation, campus backbone extension, and point-to-point links where distances exceed multi-mode or shorter-reach single-mode capability
