BlueOptics QSFP28 Transceiver 980-9I17B-00CS00-BO, MPO/MTP, 100GBASE-SR4, Multimode 4×850nm, 100 m, DDM/DOM, 0–70°C

BlueOptics QSFP28 Transceiver 980-9I17B-00CS00-BO is a compact optical module designed for 100GBASE-SR4 short-reach connections. The transceiver uses an MPO/MTP interface and multimode fiber with four parallel 850 nm lanes to deliver aggregate 100 Gbps bandwidth over distances up to 100 meters. On-board digital diagnostic monitoring (DDM/DOM) provides real-time status of optical parameters, and the module is specified to operate reliably in ambient temperatures from 0 to 70°C.

Advantages

The QSFP28 form factor offers high port density for aggregation switches and data center top-of-rack deployments while maintaining low power consumption for short-reach 100 Gbps links. Using MPO/MTP and multimode optics simplifies cabling in trunk and breakout applications. Built-in DDM/DOM enables monitoring of optical power, temperature and supply voltage for easier troubleshooting and maintenance. The module's industrial temperature range supports standard data center environments.

Suitable for

• 100G aggregation links between switches in data centers
• Top-of-rack uplinks requiring high port density
• Short-reach multimode fiber trunking and breakout applications
• Environments where optical diagnostics (DDM/DOM) are required

How to use

Install the QSFP28 transceiver into a compatible QSFP28 slot on a switch or transceiver cage following the host device vendor's insertion and removal procedures. Connect an MPO/MTP multimode fiber cable with the appropriate polarity and breakout wiring if connecting to multiple 25 G lanes or to QSFP-to-4xSFP28 adapters. Verify link status on the host device and use DDM/DOM readings to confirm optical power, temperature and voltage within expected ranges before putting the link into production.

Usage recommendations

For reliable 100GBASE-SR4 performance, use OM3/OM4 multimode fiber to achieve the specified reach and maintain proper MPO/MTP connector cleanliness. Monitor DDM/DOM metrics after installation to detect connector contamination or fiber bend losses, and ensure operating temperature remains within the 0–70°C range specified for the module.
