QSFP-transceivermodule BlueOptics QSFP-100G-LR4-IT-BO glasvezel

The BlueOptics QSFP-100G-LR4-IT-BO is a QSFP28 transceiver module engineered for 100G Ethernet long-reach applications. It uses an LC duplex fiber connector and single-mode fiber with CWDM-based transmitter and receiver stages to support optical links up to long-range distances. The module is housed in an aluminium enclosure, weighs approximately 40 g, and follows MSA form-factor and interface conventions to ensure interoperability with compatible network equipment.

Advantages

This transceiver supports 100GBASE-LR4 optical transport over single-mode fiber and integrates digital diagnostics functionality for real-time monitoring of supply voltage, laser bias current, optical output and input power, and internal temperature where supported by host hardware. Constructed with an aluminium casing and component selection aligned to industry MSA guidelines, the module is designed for reliable long-term operation and compatibility with systems that accept QSFP-100G-LR4-IT-style modules.

How to use

Install the QSFP-100G-LR4-IT-BO into a compatible QSFP28 port on your switch, router or other network device following the host vendor’s insertion and removal procedures. Connect an appropriate LC duplex single-mode patch cable to the module and the remote endpoint, ensuring proper fiber polarity. Verify link status and, if available, access the module’s digital diagnostic monitoring information through the host platform to confirm optical power levels, supply voltage and temperature. Observe ESD precautions and avoid touching the optical interfaces; keep protective dust caps on connectors when not in use.

Recommendations

Use certified single-mode LC duplex fiber patch cords and verify that the host device explicitly supports QSFP-100G-LR4-IT-style transceivers to ensure compatibility. When deploying in production, validate link performance and DDM readings during commissioning and keep spare modules on hand to minimize downtime.
