QSFP28 transceivermodule BlueOptics 9N51Y-BO 10000m aluminium

The BlueOptics 9N51Y-BO QSFP28 Transceiver Module is a 100G optical interface designed for high-speed single‑mode fiber links. Constructed with an aluminium housing and weighing 40 g, this module follows MSA QSFP28 form‑factor specifications and supports long‑reach transmission up to 10,000 metres using LC duplex connections. It supports 100GBASE‑LR4 signaling and is suitable for integration into network hardware that accepts QSFP28 optical transceivers.

Advantages

The module provides 100 Gbps aggregated throughput over single‑mode fiber with CWDM transmitter and receiver design and LC duplex connectivity. Its aluminium shell offers mechanical robustness and thermal stability in rack environments. Digital Diagnostics Monitoring (DDM/DOM) capability enables real‑time monitoring of supply voltage, laser bias current, transmit power, receive power and module temperature when supported by host hardware. The compact QSFP28 form factor allows high port density in switches and routers while maintaining compatibility with MSA standards.

Suitable for

• High‑capacity data center uplinks and spine switching
• 100G Ethernet links between core network devices
• Long‑reach single‑mode fiber connections up to 10 km
• Storage area network interconnects and aggregation links

Key specifications

• Interface type: QSFP28 (100GBASE‑LR4)
• Optical medium: single‑mode fiber with LC duplex connector
• Maximum transmission distance: up to 10,000 metres
• Housing material and colour: aluminium
• Weight: 0.04 kg
• Supports Digital Diagnostics Monitoring (DDM/DOM) per MSA SFF‑8472

How to use

Insert the QSFP28 transceiver into a compatible QSFP28 slot on a switch, router or other networking device according to the host vendor’s instructions. Connect LC duplex single‑mode fiber patch cables to the transceiver’s ports ensuring correct Tx/Rx orientation. Verify that the host device recognizes the module and, if required, enable or confirm DDM/DOM support in the device management interface to access diagnostic parameters. Observe electrostatic discharge precautions and handle the optical interfaces with clean caps removed immediately prior to connector mating.

Recommendations

Use high‑quality single‑mode LC duplex patch cords and, where possible, route fibers through appropriate patch panels to preserve connector integrity. Ensure the host device firmware supports third‑party QSFP28 modules and DDM/DOM features for full functionality. Regularly inspect and clean connectors to maintain optimal signal levels and follow manufacturer guidance for operating temperature and storage conditions.
