Key Features
Choose the Optical Link for the Site
1000BASE-LHX connects a suitable Gigabit interface to single-mode fibre. The connector, wavelength, speed and fibre type must all match the complete link. A mechanically fitting module is not proof that a switch or network card supports its optical mode.
Use the Rated Reach as a Design Limit
The 50 km rating is a maximum design reach, not a guarantee for any cable of that length. Connector loss, splices, patching, fibre condition and the remote receiver affect the result. Measure and test the commissioned link rather than relying on distance alone.
Match the Remote End
Use a remote optical interface with the corresponding speed, fibre type and compatible wavelength. Duplex optical connections use separate transmit and receive strands; preserve the correct polarity through the patching. Check the manufacturer’s host support information for each end.
Keep Maintenance Modular
The hot-pluggable SFP design allows replacement at the supported host port without restarting the entire switch. Removing the module still interrupts the traffic on that link. Follow the host’s installation procedure, handle the unit with appropriate ESD precautions and protect the optical connector from dust.
Respect Optical and Environmental Limits
The −40°C to 85°C operating range is intended for more demanding industrial environments. The surrounding switch, enclosure and power system must also suit the site. An industrial temperature rating is not a waterproof rating, and exposed optical equipment still needs suitable protection.

This offer is one SFP transceiver. The host, fibre cable, patch panels and remote optical interface are separate. Select those parts as one link design, retaining a record of the installed module identity and optical measurements for future maintenance.
Summary
The DIS-S350LHX provides a replaceable industrial fibre connection when its optical mode, cabling and supported host are selected together. Plan the remote end and optical budget before ordering, then verify the completed link so the installation has a clear, maintainable specification.
Frequently Asked Questions
Will It Work in Any SFP Slot?
No. The host must explicitly support this module, its SFP form factor, Ethernet speed and optical mode. An SFP-shaped socket or the same brand name alone does not establish compatibility.
Which Fibre Cable Does It Need?
Use 9/125 µm single-mode fibre and compatible duplex LC patching. Keep connector polarity and cleanliness under control.
Is the Maximum Distance Guaranteed?
No. The documented reach is 50 km. It depends on the complete optical path, fibre type and condition, connector/splice losses and receiver limits. Validate the installed link.
Do I Need a Different Module at the Other End?
The remote interface must match the optical mode, speed, fibre and wavelength. It can be a supported matching transceiver or another explicitly compatible interface; confirm both ends of the link.
Can a Long-Reach Module Be Used on a Short Cable?
Only if the resulting optical power is within the receiver’s permitted range. Some short links require an appropriate attenuator. Check the exact transmit/receive specifications and measure the link before use.
What Is Included?
One DIS-S350LHX transceiver. The host switch or interface, fibre cable, remote module and any required attenuation are separate. Keep the supplied module identification and host compatibility information with the installation record.
