## Summary description

The BlueOptics QSFP-40G-LR4-SO-BO is a fiber optic transceiver module designed for high-speed data transfer with a maximum rate of 40 Mbit/s. It features a QSFP interface and is made of durable metal housing. With a mean time between failures (MTBF) of 1,000,000 hours, it ensures reliability. Weighing only 20 g, it is lightweight and easy to install. Ideal for networking applications requiring efficient data communication.

## Long description

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
Key specifications
 Interface type: QSFP (quad small form-factor pluggable)
 Maximum data transfer rate: 40 Mbit/s
 Connector: LC Duplex
 Fiber type: Single-mode fiber (SMF) with CWDM channels
 Housing: Metal enclosure
 Digital diagnostics: DDM/DOM (real-time supply, bias, power, temperature)
 Weight: approx. 0.02 kg
 Compliance: MSA QSFP mechanical/electrical specifications; meets common industrial standards
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.
Usage 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.
