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.

Suitable for

• 100 Gbps short-reach uplinks in data centers
• High-bandwidth server-to-switch and switch-to-switch connections
• Enterprise core and aggregation layer links
• Storage area networks and high-speed SAN interconnects

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.

Usage 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.
