Optical transceiver BlueOptics QSFP28 BO25LS856S1D 100GBASE-SWDM4 850nm up to 100 m

BlueOptics QSFP28 BO25LS856S1D is a 100GBASE-SWDM4 optical transceiver designed for short-reach multimode fiber links up to 100 meters. The module uses an 850 nm wavelength and a QSFP28 form factor to provide 100 Gbps Ethernet connectivity in high-density data center environments. It is suitable for switch-to-switch connections, server uplinks and MPO/MTP trunking where reliable, low-latency transmission is required.

Advantages

The transceiver offers a compact QSFP28 form factor that consolidates four lanes of 25 Gbps into a single 100G interface, reducing port density and cabling complexity. Operating on 850 nm multimode fiber, it supports short-distance links up to 100 m, making it compatible with common OM3/OM4 cabling. The module is designed for low latency and consistent throughput, and it integrates with standard 100GBASE-SWDM4 deployments for simplified interoperability in modern network infrastructures.

Suitable for

• High-density data center switch-to-switch connections
• Server aggregation and uplink ports
• MPO/MTP trunking and fiber patch panels
• Short-reach multimode fiber runs within racks or between adjacent racks (up to 100 m)

Key specifications

• Form factor: QSFP28
• Data rate: 100 Gbps (four lanes of 25 Gbps)
• Standard: 100GBASE-SWDM4
• Wavelength: 850 nm
• Maximum reach: up to 100 meters over multimode fiber
• Fiber type: multimode (compatible with OM3/OM4)

How to use

Install the QSFP28 transceiver into a compatible 100G QSFP28 port on a switch or network device, ensuring the module is fully seated and the device recognizes the transceiver. Use MPO/MTP or appropriate multimode patch cables to connect to the remote port or patch panel, observing correct fiber polarity and connector orientation. Verify link status and speed via the network device management interface and perform standard testing for signal integrity and bit error rate if required.

Usage recommendations

For optimal performance, use high-quality OM3 or OM4 multimode fiber and certified MPO/MTP cabling. Keep fiber connectors clean and protected during installation to avoid signal loss. Ensure the host device supports 100GBASE-SWDM4 over QSFP28 modules and update device firmware if necessary for compatibility.
