D-Link specifies compliance with IEEE 802.3ba 100GBase-LR4. :contentReference[oaicite:3]{index=3}

10km Transmission Distance

The DEM-Q2810Q-LR4 supports optical links of up to 10km when used with appropriate single-mode fiber and compatible network equipment.

The actual achievable distance depends on fiber quality, optical loss, connector performance, patch panels, transceiver characteristics and the overall optical link budget.

Single-Mode Fiber Support

The transceiver is designed for single-mode fiber rather than multi-mode fiber. D-Link specifies support for 9/125µm single-mode optical fiber. :contentReference[oaicite:4]{index=4}

Using the correct single-mode fiber infrastructure is essential for achieving the intended 10km transmission distance.

Duplex LC Connector

The DEM-Q2810Q-LR4 uses a Duplex LC optical connector. The LC interface provides separate transmit and receive optical paths for the 100GBase-LR4 link.

Duplex LC connectivity makes the module suitable for structured fiber-optic installations using standard LC single-mode patch cables and fiber panels.

1310nm Optical Wavelength

The DEM-Q2810Q-LR4 operates across four wavelength channels in the 1310nm region. D-Link specifies the following wavelengths:

• 1295.56nm
• 1300.05nm
• 1304.58nm
• 1309.14nm

These wavelength channels are part of the 100GBase-LR4 optical architecture. :contentReference[oaicite:5]{index=5}

QSFP28 Form Factor

The DEM-Q2810Q-LR4 uses the compact QSFP28 form factor. QSFP28 modules are designed for high-density 100GbE switching environments and allow compatible network equipment to provide high bandwidth within a compact physical footprint.

D-Link describes the module as a standard QSFP28 transceiver for use in QSFP28 ports. :contentReference[oaicite:6]{index=6}

Hot-Pluggable Design

The DEM-Q2810Q-LR4 is hot-pluggable. D-Link specifies hot-swap functionality, allowing the transceiver to be installed or removed from a compatible QSFP28 port without powering down the connected networking equipment, subject to the equipment manufacturer's operating procedures. :contentReference[oaicite:7]{index=7}

Optical Power Specifications

D-Link specifies a transmit optical power range of approximately -4.3dBm to 4.5dBm and a receive range extending from approximately -10.6dBm to 4.5dBm, with sensitivity specified at -8.6dBm. :contentReference[oaicite:8]{index=8}

These optical characteristics are important when calculating the available link budget for a 10km single-mode fiber deployment.

Data Center Networking

The DEM-Q2810Q-LR4 is well suited to data center environments requiring high-speed switch interconnection. It can be deployed for connections between compatible spine, leaf, aggregation and core networking equipment.

D-Link positions its 100G QSFP28 transceivers for data centers, enterprise wiring environments and service-provider transport applications. :contentReference[oaicite:9]{index=9}

Enterprise Network Backbone

With 100Gbps throughput and up to 10km reach, the DEM-Q2810Q-LR4 can be used for high-capacity enterprise backbone and inter-building network connections where compatible single-mode fiber infrastructure is available.

It provides substantially more bandwidth than 10GbE or 25GbE optical links, making it suitable for network aggregation and backbone upgrades.

Switch-to-Switch Connectivity

The DEM-Q2810Q-LR4 can be used to establish 100GbE optical connections between compatible QSFP28-equipped switches.

Both ends of the optical link should use compatible 100GBase-LR4 optics and appropriate single-mode fiber cabling. Always verify transceiver compatibility with the exact switch model and firmware before deployment.

Power and Environmental Specifications

D-Link's published specifications identify the module as a 3.3V device with an operating temperature range of 0°C to 70°C. :contentReference[oaicite:10]{index=10}
