## Summary description

BlueOptics QSFP28 transceiver (model R7D08A-BO) supports 100GBASE-SR4 over multimode fiber using an MPO connector. It transmits on four 850 nm lanes, supports reach up to 100 meters, and provides monitoring via DDM/DOM. Designed for data center and high-speed networking equipment compatible with HPE Alletra interfaces, operating between 0°C and 70°C.

## Long description

The BlueOptics QSFP28 Transceiver R7D08A-BO is a compact 100GBASE-SR4 optical module for multimode fiber networks. It uses an MPO connector and transmits four parallel 850 nm lanes to deliver up to 100 Gbps over distances up to 100 meters on suitable multimode fiber. The module includes digital diagnostics (DDM/DOM) for real-time monitoring and is specified to operate in ambient temperatures from 0°C to 70°C. It is designed to be interoperable with equipment that supports HPE Alletra‑compatible QSFP28 interfaces and is intended for data center and enterprise high‑speed links.
Advantages
The transceiver offers a standardized QSFP28 form factor with MPO multimode connectivity, enabling 100G aggregation or server-to-switch links while retaining a small physical footprint. Four 850 nm lanes provide parallel transmission for short‑reach 100G links, and the built‑in DDM/DOM functionality allows monitoring of optical parameters such as transmit/receive power and temperature. The operating temperature range and industry‑standard optical characteristics make it suitable for typical rack and data center deployments.
Suitable for
 100G short‑reach links within data center racks or between adjacent racks using multimode fiber
 Switch-to-switch aggregation and top‑of‑rack server uplinks requiring QSFP28 ports
 Environments where real‑time optical monitoring (DDM/DOM) is required for maintenance and diagnostics
 Deployments that use MPO‑terminated multimode trunk cables and OM3/OM4 fiber supporting 100 m reach
When it may not be suitable
This module is intended for multimode short‑reach applications and is not suitable for single‑mode networks or long‑reach connections beyond the specified 100 m. It is not appropriate where different wavelengths or protocols (for example 100GBASE-LR4) are required, or when the host equipment does not accept third‑party QSFP28 transceivers.
Key specifications
 Standard: 100GBASE‑SR4
 Form factor: QSFP28
 Connector: MPO (multi‑fiber push‑on)
 Fiber type: Multimode fiber (OM3/OM4 recommended)
 Wavelength: 4 × 850 nm lanes
 Maximum reach: up to 100 m (typical on OM4/OM3 depending on conditions)
 Monitoring: DDM/DOM (digital diagnostics)
 Operating temperature: 0°C to 70°C
How to use
Install the QSFP28 transceiver into a compatible QSFP28 port on a switch, router or NIC that supports 100GBASE‑SR4 modules. Ensure the module is seated firmly and latched according to the host device instructions. Connect the MPO‑terminated multimode fiber trunk cable to the transceiver, observing correct polarity and fiber type. Verify link status through the host device and, if needed, monitor optical parameters using the DDM/DOM interface provided by the transceiver and supported by the equipment management system. Follow electrostatic discharge (ESD) precautions when handling the module and protect the MPO connector with dust caps when not connected.
What to consider before purchase
 Confirm that the host device accepts third‑party QSFP28 transceivers and supports 100GBASE‑SR4
 Verify fiber type (OM3/OM4) and channel length to ensure reliable reach up to 100 m
 Check MPO connector polarity and cable assembly type used in your cabling infrastructure
 Ensure management software or hardware supports reading DDM/DOM parameters if monitoring is required
Usage recommendations
Use OM4 multimode fiber for the best margin at 100 Gbps over distances approaching 100 m; maintain clean MPO connectors and follow vendor guidance for polarity and fiber mapping. For critical links, validate interoperability and performance in a lab or pilot before wide deployment.
