## Summary description

The BlueOptics QSFP-40G-XSR4-BO is a fiber optic transceiver module designed for high-speed data transfer at 40000 Mbit/s. It operates at a wavelength of 850 nm and features a QSFP interface. With a mean time between failures of 3000000 hours, it ensures reliability and longevity. Weighing only 40 g, this compact module is ideal for data centers and high-performance networking applications.

## Long description

The BlueOptics QSFP-40G-XSR4-BO is a compact QSFP fiber optic transceiver module engineered for 40 Gbit/s data transmission over multimode fiber. Operating at an 850 nm wavelength and featuring an MTP/MPO connector, this silver-coloured module supports links up to 300 m and is suitable for dense networking environments such as data centres and high-performance switching fabrics. With a mean time between failures (MTBF) of 3,000,000 hours and a lightweight metal housing of approximately 40 g, the module is designed for long service life and easy hot-plug use in compatible QSFP slots.
Advantages
The QSFP-40G-XSR4-BO delivers high throughput at 40 Gbit/s with low-latency optical transmission and an industry-standard QSFP form factor for broad compatibility. Use of an MTP/MPO connector simplifies multi-fiber terminations and dense cabling, while the small, robust metal module provides mechanical durability and thermal stability. Integrated digital diagnostics (where supported by host hardware) enable remote monitoring of key parameters such as optical power, temperature and supply voltage to assist with maintenance and troubleshooting.
Suitable for
40G uplinks between switches and aggregation layers in data centres
High-performance computing clusters and storage interconnects
Campus backbone links and metro short-reach connections
Network equipment supporting QSFP modules with MTP/MPO multimode interfaces
Key specifications

Wavelength: 850 nm
Maximum link distance (multimode): up to 300 m
Connector type: MTP/MPO
Form factor: QSFP (quad small form-factor pluggable)
Colour / housing: silver metal
Weight: approx. 0.04 kg
Digital diagnostics: supported when host device implements DDM/DOM
How to use
Install the QSFP-40G-XSR4-BO into an appropriate QSFP port while the host equipment is powered according to the network device manufacturer’s hot-plug guidelines. Use MTP/MPO multimode patch cables or trunk assemblies to connect to matching MPO/MTP ports or patch panels. Ensure the connected transceivers and cabling meet the required multimode specifications for 850 nm operation and the intended link distance. If the host supports digital diagnostics, monitor optical power, temperature and supply voltage via the management interface to verify correct operation and detect potential issues.
Usage recommendations
For reliable operation, verify compatibility with your switch or router vendor and use recommended multimode fiber and MTP/MPO cabling. Keep module firmware and host device software up to date and avoid bending or stressing fiber assemblies; regularly review DDM/DOM readings to maintain link performance and plan preventive maintenance.
