Fiber optic transceiver BlueOptics BO28L859S1D 100000 Mbit/s QSFP28

The BlueOptics BO28L859S1D is a QSFP28 fiber optic transceiver module designed for 100 Gbit/s networks. It implements the 100GBASE-SR4 optical standard with an MPO/MTP multi-fiber connector and operates over multimode fiber using 850 nm wavelength optics. The module follows MSA-compliant QSFP28 form-factor and is compatible with HPE platforms that support the original JL309A transceiver. Certified to CE and FCC requirements and RoHS compliant, the transceiver weighs approximately 40 g and is intended for short-reach high-bandwidth interconnects in data center and enterprise environments.

Advantages

The BlueOptics BO28L859S1D offers a compact QSFP28 interface that supports aggregated 100000 Mbit/s throughput and simultaneous transmit/receive channels via MPO/MTP connector. Compliance with MSA electrical and mechanical standards ensures interoperability with major network hardware, while CE, FCC and RoHS certifications confirm regulatory and environmental conformity. The module includes digital diagnostics monitoring (DDM/DOM) support for real-time parameters such as temperature, supply voltage and optical power, which simplifies remote monitoring and troubleshooting.

Suitable for

• 100G Ethernet interconnects between switches and routers in data centers
• High-speed server uplinks and aggregation fabrics
• Fibre Channel or SDH/SONET short-reach optical links over multimode fiber (up to typical SR distances)
• Patch panel connections and MPO/MTP trunk deployments in multi-fiber links

How to use

Install the BlueOptics BO28L859S1D by inserting the QSFP28 module into a compatible QSFP28 slot on the switch, router or host device, taking care to align the module and seat it until the latch engages. Connect an appropriate MPO/MTP multimode fiber patch cord or trunk assembly to the module, observing correct polarity and ensuring the connected fiber and patch panels meet multimode SR specifications. Confirm that the host device firmware and port settings support 100GBASE-SR4 and, if required, enable DDM/DOM monitoring in the management interface to view diagnostic data.

Recommendations

Use OM3 or OM4 multimode fiber and MPO/MTP cabling rated for 100G SR operation to achieve the best reach and signal integrity. Verify compatibility with the target hardware platform and firmware before deployment, and perform link verification and optical power checks during installation to confirm correct operation.
