QSFP Transceiver Module BlueOptics QSFP-40G-LR4-SO-BO 40 Mbit/s

The BlueOptics QSFP-40G-LR4-SO-BO is a QSFP fiber optic transceiver module engineered for single-mode optical links with a maximum data transfer rate of 40 Mbit/s. Housed in a durable metal enclosure and weighing approximately 20 g, this compact transceiver provides support for LC Duplex connections and implements CWDM-based transmit and receive channels. The module follows MSA-defined QSFP mechanical and electrical specifications and includes Digital Diagnostics Monitoring (DDM/DOM) for real-time reporting of supply voltage, laser bias current, transmit power, receive power and temperature.

Advantages

The module provides compatibility with hardware platforms that support QSFP 40GBASE-LR4 transceivers and is tested for interoperability with common switch, router and storage systems. Its metal housing and component selection are targeted to deliver long operational lifetime and high availability, reflected by an MTBF of 1,000,000 hours. Built according to MSA standards, the transceiver supports simultaneous send/receive operation over LC Duplex connectors using single-mode fiber while offering remote monitoring via DDM/DOM.

Suitable for

• 40G Ethernet links over single-mode fiber up to long-reach distances
• Fibre Channel over Ethernet and SDH/SONET high-speed applications
• Interconnects between switches, routers, storage systems and load balancers
• Environments requiring remote optical diagnostic monitoring

How to use

Install the transceiver into a compatible QSFP port on supported networking equipment following the host vendor's insertion and removal procedures. Connect LC Duplex single-mode fiber patch cords to the transmit and receive ports, ensuring correct polarity. Verify link establishment and check digital diagnostic values through the host system if DDM/DOM is supported. Follow the equipment manufacturer's guidance for hot-plug handling and ESD precautions to avoid damage during installation and removal.

Recommendations

Use high-quality single-mode LC Duplex patch cords and, where possible, route fibers through patch panels to maintain optimal link quality. Confirm that the target hardware supports 40GBASE-LR4 QSFP modules and DDM/DOM features to take full advantage of monitoring capabilities. For long-term reliability, operate the transceiver within the host equipment's specified temperature and power ranges and perform periodic checks of optical power and diagnostic readings.
