QSFP-transceivermodule BlueOptics QSFP-100G-LR4-2-BO 100G LC

The BlueOptics QSFP-100G-LR4-2-BO is a QSFP28 fiber optic transceiver module engineered for 100G long-reach Ethernet links. It uses an LC duplex interface and single-mode optics with CWDM to support 100GBASE-LR4 transmission over distances up to approximately 10 kilometers when deployed over appropriate single-mode fiber. Housed in a metal enclosure and weighing about 40 grams, the module follows MSA-compatible QSFP28 form-factor conventions to ensure physical compatibility with network equipment that accepts QSFP28 modules.

Advantages

This transceiver supports 100 Gbit/s data rates and implements CWDM-based transmit and receive optics for long-reach single-mode links. The metal housing contributes to mechanical durability and thermal dissipation while the lightweight construction simplifies handling and installation. The product includes digital diagnostic monitoring (DDM/DOM) capabilities for remote monitoring of parameters such as supply voltage, laser bias current, transmit power, receive power and temperature, provided the host platform supports these diagnostics.

How to use

Install the module into a compatible QSFP28 slot on switches, routers or other network equipment that officially supports QSFP-100G-LR4 type transceivers. Ensure the host device firmware or software recognizes third-party modules if required by the vendor. Connect LC duplex single-mode fiber patch cords between transceivers or to patch panels, respecting transmit/receive orientation. If the host supports DDM/DOM, enable or query diagnostics to monitor operating parameters during commissioning and operation. Follow electrostatic discharge (ESD) precautions and handle the module by its edges; keep optical connectors capped when not connected to avoid contamination.

Recommendations

Use high-quality single-mode LC patch cords and appropriate fiber management (patch panels, strain relief) to achieve the specified range and signal quality. Verify host compatibility and, if available, test the module in your platform before large-scale deployment. Regularly inspect and clean LC connectors to maintain optical performance and minimize insertion loss.
