HP JD061A X125 1G SFP LC LH40 1310nm Transceiver

HP JD061A X125 1G SFP LC LH40 Transceiver

This HP JD061A X125 transceiver provides a 1000Base-LH optical interface for Gigabit Ethernet links. It is intended for network administrators extending data networking connections over single-mode fibre using LC duplex connectors. The module operates at a 1310nm wavelength with a maximum data transfer rate of 1 Gbps. It suits environments requiring long-haul connectivity between switches or routers.

Check LC duplex ports and single-mode fibre

Before ordering, verify that your switch or router accepts SFP transceivers and presents an LC duplex port for 1000Base-LH operation. Confirm the installed cabling is single-mode optical fibre terminated with LC connectors. Ensure the link budget matches a 40 km reach at 1310nm and that the host device supports the 1 Gbps Gigabit Ethernet standard used by this module.

Steady 1 Gbps throughput over 40 km

Under sustained load the transceiver maintains a constant 1 Gbps data rate across the full 40 km single-mode distance. The 1310nm laser delivers stable optical power for continuous 1000Base-LH traffic without the short-burst fluctuations seen in lesser-spec modules. It is not suited for multi-mode fibre plants or links requiring reaches beyond the specified 40 km single-mode distance.
