QSFP Transceiver Module BlueOptics QSFP-100G-ESR4-MM850-BO 40000 Mbit/s

The BlueOptics QSFP-100G-ESR4-MM850-BO is a QSFP28 fiber optic transceiver module designed for 100GBASE-ESR4 links with a nominal data rate of 40000 Mbit/s. Operating at an 850 nm wavelength over multimode fiber and using an MTP/MPO connector, this compact silver module weighs approximately 40 g and fits standard QSFP interfaces used in data centers and high-performance computing environments. The module includes digital diagnostics monitoring (DDM/DOM) for real-time reading of supply voltage, laser current, optical transmit and receive power, and temperature, and its MTBF rating indicates long-term reliability.

Advantages

The module supports full-duplex 100G transmission via a QSFP28 form factor with MPO/MTP connectivity, enabling high-density and high-throughput links. Compliance with MSA-defined mechanical and electrical standards assures interoperability with equipment that supports QSFP-100G-ESR4 transceivers. Integrated DDM/DOM simplifies fault detection and remote monitoring. Engineered using high-quality optical and IC components, the transceiver offers an extended service life and stable performance in continuous operation.

Key specifications

How to use

Install the transceiver into a compatible QSFP/QSFP28 slot on a switch, router or other network device following the host vendor's insertion procedure. Connect the MTP/MPO multimode fiber patch cable to the transceiver ensuring correct polarity and secure latching. Verify link status via the network device and, where supported, check DDM/DOM readings to monitor optical power and temperature. Always handle the transceiver by its housing, keep dust caps on unused ports, and power down or follow hot-swap guidelines provided by the equipment manufacturer when inserting or removing modules.

Recommendations

Use OM3/OM4 multimode fiber for optimal reach and performance at 850 nm, and pair the transceiver with compatible MPO/MTP patch cables and hardware that support QSFP-100G-ESR4 specifications. Ensure DDM/DOM support on the host device to enable remote diagnostics. Store and transport modules in anti-static packaging and avoid exposing the optical interfaces to dust or direct sunlight to maintain signal quality and prolong service life.
