Transceiver BlueOptics BO28L859S1D (980-9I17D-00CS00-BO) QSFP28 MPO/MTP 100GBASE-SR4 multimode 4×850 nm 100 m DDM DOM 0–70 °C

BlueOptics BO28L859S1D is a QSFP28 transceiver module designed for short-reach 100 Gbps Ethernet links over multimode fiber. The module uses an MPO/MTP interface and four parallel 850 nm lanes to deliver 100GBASE-SR4 performance up to 100 meters on appropriate multimode fiber. Integrated diagnostic functions provide real-time monitoring of operating parameters to assist with network maintenance and troubleshooting. The transceiver is intended for use in data center switches, routers and high-density interconnects and operates across a standard ambient temperature range.

Advantages

The transceiver offers high-density 100 Gbps connectivity in a compact QSFP28 form factor with an MPO/MTP connector for rapid installation and fiber management. Use of four 850 nm lanes maintains compatibility with established multimode fiber infrastructures and supports distances up to 100 meters on OM3/OM4 fiber types. Built-in digital diagnostics (DDM/DOM) allow monitoring of key parameters such as temperature, optical power and supply voltage, enabling faster fault identification and simplified operation in campus and data center environments.

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port following your equipment vendor’s guidelines, ensuring the module is properly seated and latched. Connect an MPO/MTP multimode fiber trunk cable rated for OM3 or OM4 between transceivers at each end, observing correct polarity and fiber ribbon orientation. After insertion, verify link status and use the device or management system to read diagnostic information through DDM/DOM to confirm optical power levels, temperature and supply voltage are within expected ranges before placing traffic on the link.

Recommendations

For reliable 100GBASE-SR4 performance, use certified OM3 or OM4 multimode fiber and MPO/MTP connectors with proper cleaning procedures. Ensure transceiver firmware and host equipment are compatible with QSFP28 modules, and monitor diagnostic parameters periodically to detect degradation or contamination in the optical path.
