Frequently Asked Questions
What is the DEM-Q2810Q-LR4 used for?
The DEM-Q2810Q-LR4 is a 100GBASE-LR4 QSFP28 optical transceiver for 100GbE links over single-mode fiber. It helps extend uplinks between network rooms or buildings in data center, enterprise and campus networks.
What fiber and connector does it use?
Use 9/125 µm duplex single-mode fiber with LC connectors. The transceiver uses four optical wavelengths to carry 100GbE over the duplex fiber link.
How far can the link reach?
The rated reach is up to 6.21 mi (10 km) over single-mode fiber. Actual reach depends on the optical loss across the full link, including connectors, splices and patch panels.
Which switches can I use it with?
For D-Link deployments, pair it with the 100GbE QSFP28 uplinks on the DTS-5000-56S or DXS-3610 Series. For other equipment, confirm that the host supports this module and 100GBASE-LR4 on the intended port. Check the host software and port settings before ordering.
What should I confirm before deploying the link?
Confirm the host port and software at both ends, the far-end optic, and the fiber path’s total loss. Contact D-Link for host FEC requirements, optical power limits, link budget, digital diagnostics (DDM/DOM) or maximum module power.
Can I replace the transceiver while the switch is powered on?
Yes. The module is hot-pluggable, which helps simplify replacement by allowing it to be removed or installed while the host remains powered on. Removing the module interrupts the link it serves.
Are the switch and fiber cabling included?
Switches and fiber cabling are sold separately.
What warranty applies?
The DEM-Q2810Q-LR4 is backed by a 5-Year Limited Warranty.
