Axiom SFP 1000Base-LH40 Transceiver

The Axiom JD061A-AX is an SFP transceiver module built for Gigabit Ethernet links over single-mode fibre. It targets network engineers and system integrators who need a hot-pluggable LC interface for long-haul data networking. The module arrives pre-coded for OEM router and switch compatibility and carries RoHS certification. It fits any MSA-compliant slot without additional configuration.

40 km Reach and Single-Mode Operation

This module supports 1000Base-LH40 signalling, providing a nominal 40 km link distance on standard single-mode fibre. It handles campus backbone connections, metro-area links and inter-building trunks where copper cannot reach. The optical budget suits typical attenuation and splice loss on a 40 km path; beyond that distance the received power drops below the receiver sensitivity and errors increase. It does not support multi-mode fibre or shorter-reach standards such as LX or SX.

LC Duplex Interface and MSA Compliance

The transceiver presents a duplex LC connector pair and conforms to the SFP multi-source agreement for mechanical and electrical mating. It draws power from the host cage and communicates management data over the standard two-wire serial interface. Switches or routers that do not implement the MSA memory map or that enforce a proprietary vendor lock will not recognise the module. Buyers who need encrypted line-rate payloads or DWDM wavelength tuning must select a different part number.

Questions about this item

Will the JD061A-AX SFP module work in my existing MSA-compliant switch without reconfiguration?

The module is pre-configured with an application-specific code and fully MSA compliant, so it performs identically to original transceivers in any MSA-compliant platform.

How can I verify the 1000Base-LH40 link is operating correctly after installation?

Check the switch port status for a 1 Gbps link-up on the LC single-mode fiber connection; the module complies with the 1000Base-LH40 standard for 40 km reach.

Does the JD061A-AX package include the LC fiber patch cables needed for the single-mode connection?

The box contains only the SFP transceiver module; LC single-mode fiber patch cables must be purchased separately to complete the link.
