QSFP-transceiver-module BlueOptics QSFP-100G-SR4-MM850-B-CM-BO 100000 Mbit/s

The BlueOptics QSFP-100G-SR4-MM850-B-CM-BO is a QSFP28 transceiver module engineered for 100 Gbit/s optical connections over multimode fiber. Housed in a durable metal casing and weighing 40 g, the module uses an MTP/MPO connector and operates with 850 nm transmit and receive wavelengths. It supports short-reach 100GBASE-SR4 links up to 100 m and includes digital diagnostics monitoring (DDM/DOM) for real-time status information.

Advantages

This QSFP28 transceiver provides high-density 100 Gbit/s data throughput in a compact form factor, offering a balance of durability and low weight due to its metal housing. Compliance with Multi-Source Agreement (MSA) form factor and optical interface standards ensures interoperability with equipment that supports 100GBASE-SR4. Integrated digital diagnostics simplify monitoring and remote troubleshooting by reporting parameters such as supply voltage, laser bias current, transmit output and receive input power, and temperature.

How to use

Install the QSFP-100G-SR4 module into a compatible QSFP28 port on switches, routers or host adapters following the equipment vendor's insertion and hot-plug procedures. Connect an appropriate MTP/MPO multimode fiber patch cord, ensuring correct polarity and using OM3/OM4 multimode cable to reach distances up to 100 m. Verify that the host device supports 100GBASE-SR4 and, if required, enable DDM/DOM access via the device management interface to read real-time diagnostic parameters.

Recommendations

Use high-quality OM3 or OM4 multimode fiber and certified MTP/MPO patch cords to achieve the specified 100 m reach. Ensure firmware and driver compatibility on network equipment to allow full functionality of the transceiver and DDM features. For best long-term performance, follow manufacturer cleaning and handling procedures for MPO connectors and avoid excessive bending or tension on fiber cabling.
