Fiber optic transceiver module BlueOptics WRJMF-BO 40000 Mbit/s QSFP

The BlueOptics WRJMF-BO is a fiber optic transceiver module designed for high-speed network links with a QSFP interface and a maximum data transfer rate of 40000 Mbit/s. The module is compact and lightweight, with a silver housing and a weight of approximately 20 g. It supports single-mode fiber connections using LC duplex connectors and is RoHS compliant, making it suitable for integration into switches, routers and other network equipment that accept QSFP transceivers.

Advantages

This BlueOptics QSFP transceiver delivers up to 40 Gbit/s throughput while maintaining a compact form factor. It is constructed to MSA-compatible QSFP specifications and carries compatibility with hardware platforms that accept equivalent 40G QSFP-LR4 optics. The module incorporates high-quality optical and electronic components to provide extended service life and stable performance. Built-in digital diagnostics (DDM/DOM) enable real-time monitoring of key parameters such as supply voltage, laser bias current, transmit power, receive power and temperature when supported by the host device.

Suitable for

• 40G Ethernet uplinks and aggregation links in data centers
• High-speed interconnects between switches and routers
• Fibre Channel over Ethernet (FCoE) and other SAN connections
• Long-reach single-mode fiber links up to several kilometers

• Connector type: LC duplex (single-mode)
• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Operating monitoring: Digital Diagnostics (DDM/DOM) compatible
• Colour: Silver
• Weight: 0.02 kg

How to use

Install the BlueOptics WRJMF-BO by inserting the QSFP module into a compatible QSFP port on your switch, router or other networking device while the device is powered down or following the host vendor’s hot-plug instructions. Terminate both ends of the single-mode fiber with LC duplex connectors and connect to the module’s LC socket. After insertion and link negotiation, verify the link status on your host device and, if supported, read DDM/DOM parameters from the management interface to confirm power levels and temperature. Follow your equipment vendor’s guidelines for fiber routing, bend radius and connector cleaning to maintain signal integrity.

Recommendations

Use single-mode fiber patch cords and LC duplex connectors certified for the target distance and keep connectors clean. Ensure the host device supports 40G QSFP-LR4 type optics and DDM/DOM if you require monitoring. For long-term reliability, avoid exposing the module to extreme temperatures or mechanical stress and follow ESD handling precautions when installing or removing the transceiver.
