Fiber optic transceiver module BlueOptics BO25LS856S1D-BO 100000 Mbit/s QSFP28

The BlueOptics BO25LS856S1D-BO is a QSFP28 fiber optic transceiver module designed for 100 Gigabit Ethernet links. It supports a maximum data transfer rate of 100000 Mbit/s and uses an LC duplex connector for multimode fiber. The module implements the 100GBASE-SWDM4 optical standard with transmit and receive wavelengths in the 832–918 nm range, and includes Digital Diagnostics Monitoring (DDM/DOM) compatible with MSA SFF-8472 where supported by the host equipment. The transceiver is supplied in a compact, silver housing and weighs approximately 40 g.

Advantages

The BO25LS856S1D-BO offers high-speed 100 Gigabit Ethernet performance in a pluggable QSFP28 form factor, enabling bandwidth upgrades without major system changes. The module follows MSA standards for electrical, mechanical and functional interoperability, and is compatible with common switches, routers, storage systems and measurement devices that support QSFP28 100GBASE-SWDM4 optics. Integrated DDM/DOM provides real-time monitoring of supply voltage, laser current, transmit and receive power and temperature to assist with remote diagnostics and maintenance. The transceiver is manufactured using industry-grade optical and electronic components to provide long service life and stable operation.

How to use

Install the BO25LS856S1D-BO into a QSFP28 port of compatible network equipment following the vendor’s hot-plug procedures. Connect LC duplex multimode fiber patch cables with matching polarity to the module’s LC ports and ensure the receiving side is mated with a compatible QSFP28 transceiver or fiber termination. Verify that the host device recognizes the module and, if required, enable or check DDM/DOM readouts in the management interface for optical parameters. Observe standard ESD precautions when handling the module and keep protective caps on the optical connectors when not in use.

Recommendations

For optimal performance, use multimode fiber and patch cables that meet OM3/OM4 specifications, confirm compatibility with the host hardware and firmware, and ensure link budgets and polarity conform to the 100GBASE-SWDM4 requirements. If DDM/DOM monitoring is needed, verify that the host system supports MSA SFF-8472 to access diagnostic data. Store and handle the transceiver in a clean, low-dust environment and replace connector dust caps when the module is idle.
