## Summary description

The BlueOptics QSFP-40G-LR4-DE-BO is a fiber optic transceiver module with a maximum data transfer rate of 40 Mbit/s. It features a QSFP interface and is designed for high-speed data communication. The module is housed in a durable metal casing and has a mean time between failures (MTBF) of 1,000,000 hours. It operates at an input voltage of 3.3 V and weighs only 20 g, making it a reliable choice for network applications.

## Long description

The BlueOptics QSFP-40G-LR4-DE-BO is a QSFP fiber-optic transceiver module designed for 40 Mbit/s optical links over single-mode fiber. The module uses a QSFP interface in a metal housing, operates from a 3.3 V input, and weighs approximately 20 g. It provides a compact, MSA-compliant solution for high-speed Ethernet and optical networking equipment that require QSFP form-factor modules and includes optical transmit and receive channels with CWDM support.
Advantages
This QSFP transceiver is built to meet MSA mechanical and electrical standards, enabling interoperability with a wide range of networking hardware that supports QSFP modules. The metal casing and selected components contribute to a long mean time between failures (MTBF) of around 1,000,000 hours, supporting sustained availability in rack-mounted switches, routers and storage systems. The module supports digital diagnostics (DDM/DOM) for remote monitoring of supply voltage, laser bias, optical output/input power and temperature when the host hardware exposes that interface.
Suitable for
40G Ethernet links over single-mode fiber
High-speed interconnects between switches, routers and storage systems
Optical backbone connections up to several kilometers (single-mode)
Environments requiring MSA-compliant QSFP modules and digital diagnostics
Key specifications
Interface type: QSFP
Maximum data transfer rate: 40 Mbit/s
Fiber type: single-mode fiber (SMF) with LC duplex connector
Optical multiplexing: CWDM for Tx/Rx channels
Operating voltage: 3.3 V
Housing: metal enclosure
Weight: approx. 0.02 kg
Digital diagnostics: DDM/DOM (MSA SFF-8472 compliant), if supported by host
MSA compliance: QSFP MSA (mechanical/electrical/functional compatibility)
How to use
Install the transceiver into a compatible QSFP port on supported network equipment, taking care to follow the host vendor’s hot-plug procedures. Connect LC duplex single-mode fiber patch cords to the module’s receptacle, ensuring correct Tx/Rx alignment and clean connector endfaces to avoid signal loss. Verify that the host device recognizes the module and, where available, enable or read DDM/DOM parameters for link diagnostics. Observe ESD precautions during handling and avoid mechanical stress to the module and fiber cables.
Usage recommendations
Use single-mode LC duplex patch cords and, where possible, a patch panel to secure connections; maintain connector cleanliness and check DDM/DOM readings for early indication of link issues. Confirm host compatibility with QSFP modules and digital diagnostic features before deployment.
