## Summary description

Compatible BlueOptics BO28L859S1D QSFP28 optical transceiver (04WGYD-BO) for 100GBASE-SR4 links. Uses MPO/MTP connector for multimode fiber with four 850 nm lanes, supporting up to 100 meters. Provides DDM/DOM for diagnostics and operates in 0°C to +70°C. Designed for data center switches and high-speed aggregation links requiring short-range 100GbE connectivity.

## Long description

BlueOptics BO28L859S1D (04WGYD-BO) is a QSFP28 multimode optical transceiver designed for 100GBASE-SR4 short-range Ethernet links. The module uses an MPO/MTP interface and transmits data over four 850 nm lanes, supporting multimode fiber runs up to 100 meters. It includes digital diagnostics monitoring (DDM/DOM) and operates over an industrial temperature range suitable for standard data center environments.
Advantages
This QSFP28 transceiver provides native 100GbE connectivity in a compact form factor compatible with equipment that accepts MPO/MTP QSFP28 modules. The multimode 850 nm design enables economical short-reach links while the DDM function allows real-time monitoring of optical parameters such as optical power and temperature. Operating across a 0°C to +70°C range ensures reliable performance in typical rack and data center deployments.
Suitable for
 100 Gigabit Ethernet links within data centers
 Short-range aggregation and spine-leaf network connections
 Multimode fiber installations with MPO/MTP trunking
 High-density switch ports and QSFP28-compatible equipment
Key specifications
 Form factor: QSFP28
 Standard: 100GBASE-SR4
 Optical interface: MPO/MTP
 Wavelength: 4 × 850 nm lanes
 Maximum reach: up to 100 m on multimode fiber
 Diagnostic: DDM/DOM supported
 Operating temperature: 0°C to +70°C
How to use
Install the QSFP28 module into a compatible QSFP28 port on a switch or network device following the vendor's hot-plug guidelines. Connect an MPO/MTP multimode fiber trunk cable to the transceiver, ensuring correct lane mapping and polarity for 100GBASE-SR4 operation. Verify link status and monitor diagnostic parameters via the host device to confirm optical power levels and temperature remain within expected ranges.
Usage recommendations
Use multimode fiber rated for 100GBASE-SR4 (OM3/OM4) to achieve the specified 100 m reach, and avoid bending or contaminating MPO/MTP connectors. Regularly check DDM readings through management interfaces to detect signal degradation early and maintain consistent short-range 100GbE performance.
