QSFP Transceiver Module BlueOptics QSFP-100G-ESR4-S-BO 100000 Mbit/s 850 nm

The BlueOptics QSFP-100G-ESR4-S-BO is a QSFP28 fiber optic transceiver module engineered for high-speed links up to 100000 Mbit/s over multimode fiber. Operating at an 850 nm wavelength with an MPO/MTP connector, this compact silver module supports 100GBASE-ESR4 applications and is compatible with common hardware platforms that accept QSFP-100G-ESR4 transceivers. With a lightweight design (approximately 40 g) and an MTBF of about 3,000,000 hours, the module is intended for integration into switches, routers, storage systems and other network devices where reliable 100 Gbps optical connectivity is required.

Advantages

The module combines a QSFP28 form factor with MPO/MTP multimode fiber connectivity to deliver full-duplex 100 Gbps transmission while maintaining compact dimensions and low weight. It includes transmitter and receiver functions at 850 nm and implements Digital Diagnostics Monitoring (DDM/DOM) compatible with MSA SFF-8472 for real-time monitoring of voltage, laser bias current, transmit/receive power and temperature. Built to MSA standards and assembled from high-quality optical and electronic components, the transceiver offers long operational life and wide compatibility with devices that support the 100GBASE-ESR4 specification.

How to use

Insert the QSFP-100G-ESR4-S-BO transceiver into a compatible QSFP28 slot on the network device until it clicks into place. Use MPO/MTP multimode fiber patch cords of the correct polarity to connect the module to matching transceivers or patch panels. Ensure the host device supports 100GBASE-ESR4 optics and, if required, enable or verify DDM/DOM support to monitor optical parameters. Follow the equipment vendor’s procedures for hot-plug handling and grounding to avoid electrostatic damage.

Recommendations

Use factory-tested MPO/MTP multimode patch cables and ensure fiber types and link budgets match the 300 m maximum reach. For remote monitoring and troubleshooting, confirm DDM/DOM support in the host hardware and verify recorded optical parameters regularly. Observe handling precautions: keep transceiver dust caps on when not in use and avoid bending fiber beyond recommended radii to maintain optimal performance.
