BlueOptics Q28-502T-BO network transceiver module Fiber optic 100000 Mbit/s QSFP28

The BlueOptics Q28-502T-BO is a QSFP28 fiber optic network transceiver module engineered for 100000 Mbit/s (100 Gbps) high-speed links. Housed in a durable metal enclosure and weighing 40 g, this silver-coloured module uses a QSFP28 interface and supports multimode fiber with an MPO/MTP connector according to MSA standards. It implements 100GBASE-SR4 signaling with 850 nm transmitter and receiver wavelengths for short-reach optical connections, and includes support for Digital Diagnostics Monitoring (DDM/DOM) to report supply voltage, laser bias current, transmit power, receive power and temperature in real time.

Advantages

The module offers a compact QSFP28 form factor compatible with equipment that accepts 100GBASE-SR4 transceivers, providing up to 100 Gbit/s throughput for data center and enterprise applications. A metal housing ensures mechanical robustness and thermal stability, while DDM/DOM support simplifies remote diagnostics and maintenance. Designed and tested to MSA interoperability guidelines, the transceiver is suitable for deployments requiring predictable performance and long operational lifetime.

How to use

Insert the QSFP28 transceiver into a compatible QSFP28 port on the switch, router or other network device while the host port is powered down or supporting hot-plug insertion per the device manual. Connect an appropriate MPO/MTP multimode fiber patchcord between the transceiver and the corresponding patch panel or transceiver at the other end, observing correct polarity and fiber type (OM3/OM4 recommended for 100GBASE-SR4 distances). Verify that the host hardware recognizes the module and, if required, enable DDM/DOM monitoring in the management interface to view real-time diagnostics data.

Recommendations

For reliable 100 Gbps performance, use quality OM3 or OM4 multimode fiber and MPO/MTP cabling assemblies rated for 100GBASE-SR4. Ensure the network device firmware supports third-party QSFP28 modules and DDM/DOM if remote diagnostics are required. Follow ESD precautions and manufacturer guidelines when handling and installing the transceiver to avoid damage.
