QSFP-lähetin-vastaanotin BlueOptics QSFP-40G-XSR4-BO 40000 Mbit/s 850 nm

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

• Data rate: 40,000 Mbit/s
• 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.

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.
