The US Transceivers compatible SFP-25G-BX40D-I is a 25GBASE-BX40-D SFP28 BiDi transceiver designed as a drop-in replacement for Cisco SFP-25G-BX40D-I deployments. Operating in the downstream direction, this module transmits at 1330 nm and receives at 1270 nm over a single strand of OS2 single-mode fiber, supporting link distances of up to 40 km. The LC Duplex connector interface simplifies cabling and reduces fiber plant costs by eliminating the need for fiber pairs.
Engineered to industrial temperature specifications (-40 to 85 deg C), this transceiver is well suited for demanding environments where thermal stability is critical. Digital Diagnostic Monitoring (DDM/DOM) provides real-time visibility into key parameters including optical power, temperature, voltage, and bias current, enabling proactive network management.
This TAA compliant module meets IEEE 802.3 and SFP28 MSA standards, making it a reliable, cost-effective choice for data center interconnect, enterprise campus aggregation, metropolitan area networking, and service provider edge deployments.
