QSFP transceiver-module BlueOptics QSFP-100G-LR4L-WDM1300-BO 100000 Mbit/s

The BlueOptics QSFP-100G-LR4L-WDM1300-BO is a QSFP28 fiber optic transceiver module designed for 100 Gbit/s optical links over single-mode fiber. It supports LC duplex connectors, a maximum link distance of up to 2000 m and comes in a compact, silver housing weighing approximately 40 g. The module implements CWDM-based LR4L optics in a QSFP form factor and includes digital diagnostics for real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature when supported by the host hardware.

Advantages

This QSFP transceiver delivers 100 Gbit/s throughput with a small, standardized QSFP28 form factor that simplifies integration into switches, routers and storage systems that accept QSFP modules. The LC duplex interface provides a commonly used fiber termination, while the CWDM LR4L design enables extended reach up to 2 km over single-mode fiber. Integrated digital diagnostics allow remote monitoring of key optical and electrical parameters to support troubleshooting and maintenance.

How to use

Install the BlueOptics QSFP-100G-LR4L-WDM1300-BO into a compatible QSFP28 port following the host device vendor's insertion and hot-plug guidelines. Connect LC duplex single-mode fiber patch cords to the module's LC connectors, observing correct transmit/receive orientation. Verify the host hardware supports the QSFP28 interface and, if required, DDM/DOM monitoring to access diagnostic values. After physical installation, confirm link status and negotiate the desired 100G protocol on both endpoints according to your network configuration procedures.

Recommendations

Use high-quality single-mode LC patch cords and appropriate patch panels to achieve the specified reach and signal quality. Ensure the transceiver is used in hardware that supports 100GBASE-CWDM4 or compatible QSFP28 modules and enable DDM/DOM in the host system if remote monitoring is needed. Avoid exposure to excessive dust, humidity or mechanical stress during installation and store spare modules in anti-static packaging.
