Fibre Connectivity Specified for the Link The DEM-Q2810Q-LR4 is a 100GbE QSFP28 optical transceiver for compatible network equipment. It uses a duplex LC connection and 9/125 µm single-mode fibre to support a specified reach of up to 10 km.

Deskripsi
Fibre Connectivity Specified for the Link
The DEM-Q2810Q-LR4 is a 100GbE QSFP28 optical transceiver for compatible network equipment. It uses a duplex LC connection and 9/125 µm single-mode fibre to support a specified reach of up to 10 km. It provides an optical connection choice for supported switches, servers and aggregation equipment.
Match the module to the host’s supported QSFP28 port, fibre type and optical standard at both ends. The 0°C to 70°C operating range applies to the module; the whole installation must also stay within the ratings of the switch, cables and enclosure. A pluggable form factor does not by itself guarantee interoperability with every vendor or every port.

Key Features
Choose the Right Optical Medium
This module is designed for 9/125 µm single-mode fibre. The link needs the correct cable, connectors and a matching optical specification at the other end. Assess the installed fibre and connector loss as well as route length before selecting the link.
Match the Host Port
The QSFP28 form factor is intended for supported 100GbE equipment. Check the exact switch or adapter model, supported firmware, port mode and compatibility list. A QSFP28 slot or module does not automatically provide four independently usable 25G links; port mode and optical design must match.
A Defined Fibre Link
The optical interface uses 1295 / 1300 / 1304 / 1309 nm wavelengths with duplex LC connectors. Two fibre paths carry transmit and receive traffic. Match the optical standard and link budget at both ends; this is not a single-fibre bidirectional module, a copper adapter or a cable that converts incompatible Ethernet standards.
Temperature Rating Where It Matters
The module operates from 0°C to 70°C. This is the module’s commercial operating range, so check cabinet airflow and the host’s thermal requirements. It should not be treated as a hardened outdoor transceiver just because it is metal.
Service a Supported Port
Hot-pluggable construction allows insertion or replacement in equipment that supports the feature. Work on the affected link still interrupts that connection, so plan a maintenance window or a tested redundant path where necessary. Keep fibre end faces clean and use the protective caps when the module is not connected.
Plan the Complete Optical Connection
The offer is an optical module. Fibre patch leads, a second compatible endpoint and any required switch or adapter are separate. Before deployment, confirm connector type, optical loss, fibre grade and the host compatibility matrix so the complete connection is specified rather than relying on the module’s headline distance alone.
Summary
The DEM-Q2810Q-LR4 gives supported 100GbE equipment a defined single-mode fibre connection. Select the correct host port, matching optical endpoint and fibre cable for a reliable installation.

Will It Work in Any Pluggable Port?
No. Confirm the host explicitly supports this 100GbE QSFP28 module and the required port mode. A physically similar socket does not guarantee compatibility.
Does It Use One Fibre Strand?
No. It uses a duplex LC connection with separate transmit and receive fibre paths. It is not a single-fibre bidirectional module.
Is It an Industrial-Temperature Module?
No industrial-temperature claim is made for this module. Its specified operating range is 0°C to 70°C.
Can It Be Replaced While the Switch Is Powered?
It is hot pluggable when used in supported equipment. The affected link disconnects during replacement; plan maintenance or a redundant path if interruption matters.
Are Fibre Cables Included?
No. Fibre patch leads and the matching equipment or module at the other end are selected separately.
