The US Transceivers compatible J9142B is a 1000BASE-BX-D SFP transceiver designed for downstream bidirectional Gigabit Ethernet applications. Operating in the SFP form factor, this module transmits at 1490 nm and receives at 1310 nm over a single strand of SMF, supporting link distances up to 10 km. The downstream designation makes it the ideal pairing with a 1000BASE-BX-U upstream module at the opposite end of the fiber link.
Built to meet IEEE 802.3ah and SFP MSA standards, this US Transceivers compatible module supports Digital Diagnostic Monitoring (DDM) for real-time visibility into key performance parameters such as optical power, temperature, and voltage. It is TAA compliant and meets RoHS, CE, and REACH requirements, making it suitable for government and regulated enterprise deployments.
This module is a cost-effective, fully compatible alternative for use in HP networking equipment, delivering reliable Gigabit connectivity for enterprise access layer, campus distribution, and SMB network environments.
