D-Link DEM-435XT 10GbE Multimode 220 m SFP+ Transceiver

Extend a Managed Network Over the Right Fibre The DEM-435XT is a 10GBASE-LRM SFP+ transceiver for a compatible 10GbE switch or network interface. It connects over multimode fibre using a duplex lc interface. Its compact hot-pluggable design makes the optical connection replaceable without treating the whole switch as a fixed fibre interface. Reach depends on the installed multimode fibre: allow up to 100 m on OM1 and 220 m on supported OM2, OM3 or OM4. Highlights Optical Connection 10GBASE-LRM for 10GbE over multimode fibre. Duplex LC. Matching host and remote optical interfaces are required. Distance and Fibre 100 m on OM1; up to 220 m on OM2/OM3/OM4. 50/125 µm or 62.5/125 µm multimode fibre; reach varies by grade. Calculate optical loss and receiver limits before installation. Installation Hot-pluggable SFP+ form factor. 3.3 V power supplied by a compatible host slot. Check host support, firmware and operating limits. Key Features Choose the Optical Link for the Site 10GBASE-LRM connects a suitable 10GbE interface to multimode 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 OM1 multimode fibre is rated up to 100 m, while supported OM2, OM3 and OM4 can reach up to 220 m. This is a 1310 nm LRM module, so it must not be selected as though it were an 850 nm SR optic. 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 Confirm the host and module operating conditions before installation. Long-reach optics may require attenuation on a short or low-loss link to avoid exceeding the receiver’s maximum input. Use an optical power meter and the documented transmit/receive limits to validate the installation. Complete the Link With the Correct Equipment 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 DEM-435XT provides a replaceable 10GbE 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?ExpandCollapse 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?ExpandCollapse Use 50/125 µm or 62.5/125 µm multimode fibre and compatible duplex LC patching. Keep connector polarity and cleanliness under control. Is the Maximum Distance Guaranteed?ExpandCollapse No. The documented reach is 100 m on OM1; up to 220 m on OM2/OM3/OM4. 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?ExpandCollapse 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?ExpandCollapse 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?ExpandCollapse One DEM-435XT transceiver. The host switch or interface, fibre cable, remote module and any required attenuation are separate. This is the non-DDM offer; digital diagnostics are not included. 더 보기
