## Summary description

The BlueOptics BO28L859S3D-BO is a QSFP28 fiber optic transceiver module designed for high-speed data transfer up to 100000 Mbit/s. It features a silver color and is compatible with various BlueOptics products, ensuring reliable connectivity for data centers and networking applications.

## Long description

The BlueOptics BO28L859S3D-BO is a QSFP28 fiber optic transceiver module designed for high-speed optical networking. It supports up to 100000 Mbit/s using the QSFP28 interface and is intended for multimode fiber links with MPO/MTP connectors. The module implements 100GBASE-SR4 signaling using 850 nm optics for transmit and receive channels and conforms to MSA-defined mechanical and electrical specifications to ensure interoperability with compatible switches, routers and storage systems.
Advantages
This QSFP28 transceiver provides up to 100 Gbit/s aggregated throughput over multimode fiber with MPO/MTP connectivity, minimizing electromagnetic interference and latency typical for copper links. It is manufactured to MSA standards and undergoes compatibility testing to work with major hardware platforms that support the original part. Integrated digital diagnostics (DDM/DOM) enable real‑time monitoring of supply voltage, laser bias current, optical output/input power and module temperature for simplified maintenance and troubleshooting.
Suitable for
100G Ethernet links in data center aggregation and spine layers
High-throughput interconnects between switches and routers
Storage area network and high-performance computing interconnects
Short-reach multimode fiber connections up to typical SR4 distances
Key specifications
Interface type: QSFP28
Maximum data transfer rate: 100000 Mbit/s (100 Gbit/s)
Optical wavelength: 850 nm (Tx and Rx)
Connector type: MPO/MTP
Fiber type: Multimode fiber (MMF)
Form factor: QSFP28 pluggable transceiver
Color / housing: Silver
How to use
Install the transceiver into a compatible QSFP28 port on network equipment following the device manufacturer's hot‑swap and electrostatic discharge (ESD) guidelines. Use an MPO/MTP multimode patch cord or patch panel to connect the transceiver to the remote transceiver. Confirm that the host hardware supports 100GBASE-SR4 and DDM/DOM if monitoring is required. After insertion, verify link status and optical power levels via the host system management interface or the module's diagnostics.
Usage recommendations
For optimal performance, use industry‑standard multimode fiber and certified MPO/MTP patch cords, adhere to recommended distance limits for 100GBASE‑SR4 multimode links, and ensure transceiver firmware and host device software are up to date. Observe ESD handling precautions during installation and allow the module to reach operating temperature before relying on measured diagnostic values.
