## Summary description

BlueOptics QSFP28 transceiver model BO25LS856S1D supports 100GBASE-SWDM4 single-lambda multiple-wavelength short-reach transmission over multimode fiber up to 100 meters. Designed for 100 Gigabit Ethernet QSFP28 ports, it enables high-density data center and enterprise interconnects, reducing cabling complexity and providing reliable short-range 100G links.

## Long description

The BlueOptics QSFP28 BO25LS856S1D is a 100GBASE-SWDM4 network transceiver designed for short-reach multimode fiber links up to 100 meters. Compatible with QSFP28 100 Gigabit Ethernet ports, this module uses single-lambda multiple-wavelength short-reach technology to deliver four 25 Gbps channels over standard multimode fiber, enabling reliable high-density interconnects in data centers and enterprise networks while reducing cabling complexity.
Advantages
This transceiver supports 100GBASE-SWDM4, providing four parallel 25 Gbps lanes over a single multimode fiber pair for efficient use of existing fiber infrastructure. The QSFP28 form factor offers high port density and hot-pluggable installation, which simplifies maintenance and upgrades. The module is engineered for compatibility with QSFP28 ports and typical data center environments, offering stable short-range performance and predictable signal integrity over multimode fiber up to 100 m.
Suitable for
 100 Gigabit Ethernet uplinks between switches in data center racks
 Server-to-switch or switch-to-switch short-range interconnects
 High-density aggregation in enterprise network closets and campus cores
 Upgrading multimode fiber infrastructure to 100G without replacing fiber cabling
Key specifications
 Standard: 100GBASE-SWDM4 over multimode fiber
 Form factor: QSFP28, hot-pluggable
 Maximum reach: up to 100 meters on multimode fiber
 Data rate: aggregate 100 Gbps (4 × 25 Gbps)
 Wavelength: SWDM single-lambda multiple-wavelength short-reach signaling
 Fiber type: multimode fiber (MMF)
 Typical applications: data center and enterprise short-range links
How to use
Install the QSFP28 transceiver into a compatible 100G QSFP28 port until it clicks into place, observing proper handling to avoid static discharge and contamination of the optical interfaces. Connect the multimode fiber patch cable with appropriate MPO/MTP or duplex connectors as required by the cable and port setup. Verify link status and port configuration on the connected switches or network devices, and monitor performance metrics through the host system's management interface. For hot-plug operations, follow the equipment manufacturer's guidance to avoid disrupting traffic on adjacent ports.
Usage recommendations
Use OM3/OM4 multimode fiber with suitable MPO/MTP cabling to achieve the specified 100 m reach. Ensure optical connectors are clean before mating and maintain proper bend radius for fiber runs. Confirm firmware and compatibility notes on the host device if vendor interoperability policies apply, and test links after installation to validate performance.
