## Summary description

The BlueOptics QSFP-40G-LR4-QL-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 housed in a durable metal casing. With an MTBF of 1,000,000 hours, it ensures reliability for long-term use. The module operates at an input voltage of 3.3 V and weighs only 20 g, making it a lightweight and efficient choice for network applications.

## Long description

The BlueOptics QSFP-40G-LR4-QL-BO is a QSFP fiber optic transceiver module engineered for high-speed single-mode fiber links with a maximum data transfer rate of 40 Mbit/s. Encased in a metal housing and weighing approximately 20 g, the module operates from a 3.3 V supply and is built for continuous operation with a specified MTBF of 1,000,000 hours. The module uses LC duplex connections and follows MSA-compliant QSFP form-factor conventions for compatibility with network equipment that supports QSFP transceivers.
Advantages
The module provides stable optical transmission over single-mode fiber using CWDM-based transmitter and receiver elements and supports standard QSFP electrical, mechanical and functional interfaces. Its compact metal enclosure and low weight make installation straightforward while the high MTBF indicates a design focused on long operational lifetime. Digital diagnostics (DDM/DOM) functionality enables real-time monitoring of operating parameters where supported by host hardware.
Suitable for (use cases)
 40G links between switches and routers over single-mode fiber
 High-speed connections in data centers and campus networks
 Interconnects for storage systems and network appliances that accept QSFP modules
 Long-reach optical links up to several kilometers when used with appropriate single-mode fiber and patching
Key specifications
 Interface type: QSFP
 Maximum data transfer rate: 40 Mbit/s
 Connector: LC duplex (optical)
 Fiber type: single-mode fiber (SMF)
 Operating voltage: 3.3 V
 Housing: metal enclosure
 Weight: 0.02 kg
 MTBF: 1,000,000 hours
 Digital diagnostics: DDM/DOM capable (host support required)
How to use
Install the QSFP module into a compatible QSFP port on a switch, router or other network device following the host manufacturer's insertion/removal procedure. Use LC duplex single-mode patch cords to connect the transceiver to the remote optical device or patch panel, ensuring correct transmit/receive orientation. Verify that the host device supports the QSFP form factor and that DDM/DOM monitoring is enabled in the host software if you intend to monitor optical parameters. Power is supplied through the host chassis at 3.3 V; no external power connection is required to the module itself.
Usage recommendations
For reliable performance, pair the transceiver with single-mode LC duplex fiber cables and maintain clean connector endfaces. Confirm compatibility with the target hardware platform and enable digital diagnostics in the host system to monitor voltage, temperature and optical power. Follow ESD precautions during handling and adhere to the host vendor’s guidelines for hot-plugging and firmware compatibility.
