QSFP-lähetin-vastaanotin BlueOptics QSFP-40G-CSR4-MM850-H-BO 40000 Mbit/s 850 nm

The BlueOptics QSFP-40G-CSR4-MM850-H-BO is a QSFP form-factor fiber optic transceiver module designed for 40 Gbit/s links over multimode fiber. It operates at an 850 nm wavelength and uses an MPO/MTP fiber connector to support parallel multimode transmission up to 300 m. The module includes both transmit and receive optics and implements Digital Diagnostics Monitoring (DDM/DOM) for real-time status of voltage, temperature and optical power, enabling monitoring and remote diagnostics in compatible systems.

Advantages

The transceiver supports high throughput at 40 Gbit/s in a compact QSFP package and is compatible with common hardware platforms that accept QSFP-40G-CSR4-style MPO/MTP modules. Use of multimode 850 nm optics reduces sensitivity to EMI and allows dense, short-reach data center and aggregation connections. Integrated digital diagnostics and proven component selection contribute to long mean time between failures, enhancing availability in critical network environments.

Key specifications

How to use

Install the module into any compatible QSFP slot following the host hardware vendor's hot-plug and ESD handling procedures. Connect an MPO/MTP multimode patch cable to the transceiver and ensure the opposing transceiver or patch panel is wired for the corresponding parallel lanes. Verify link status and diagnostics via the host device management interface; if supported, monitor voltage, temperature and optical power using DDM/DOM. Ensure the connected fiber type and patch cord meet multimode OM3/OM4 specifications to achieve the rated distance.

Recommendations

For reliable operation, use high-quality MPO/MTP multimode patch cables compatible with OM3/OM4 grades, maintain proper fiber cleanliness, and verify that the host hardware supports DDM/DOM and QSFP-40G-CSR4-style modules. Follow manufacturer guidelines for insertion/removal and ESD precautions to preserve service life and MTBF.
