BlueOptics ONS-QSFP28-LR4-BO network transceiver module QSFP28 Fiber optic LC connector

The BlueOptics ONS-QSFP28-LR4-BO is a QSFP28 fiber optic network transceiver module designed for 100G optical links. It uses a QSFP28 electrical interface and an LC duplex optical connector for single-mode fiber connections, enabling high-speed data transmission over long distances. The module is lightweight (0.04 kg) and finished in aluminium colour, and it is engineered to meet MSA form-factor and optical behaviour for compatibility with major network hardware that supports 100GBASE-LR4 optics.

Advantages

This QSFP28 LR4 transceiver supports 100G Ethernet and similar high-speed protocols over single-mode fiber up to multi-kilometre ranges, providing stable optical performance with separate CWDM transmitter and receiver channels. The module includes digital diagnostic monitoring (DDM/DOM) functionality for real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature where the host hardware supports it. BlueOptics devices are manufactured to MSA standards and use selected optical and electronic components to achieve long operational lifetime and predictable behaviour in supported platforms.

Suitable for

• 100G core and aggregation switches and routers
• Data center interconnects and spine-leaf fabrics
• High-bandwidth storage and SAN connections (FCoE, Fibre Channel over Ethernet)
• Long-reach optical links over single-mode fiber up to about 10 km

Key specifications

• Interface type: QSFP28 electrical form factor

• Typical reach: up to approximately 10 kilometres (dependent on fiber and link conditions)
• Diagnostic capability: Digital Diagnostics Monitoring (DDM/DOM) compliant with MSA SFF-8472 (host support required)
• Weight: 0.04 kg
• Housing colour: aluminium

How to use

Install the BlueOptics QSFP28 transceiver into a compatible QSFP28 port on a switch, router or storage device while the system is powered down or following the equipment manufacturer's hot-plug procedures. Connect LC duplex single-mode fiber patch cords between transceivers or to a patch panel, ensuring correct polarity and clean connectors. Verify that the host device supports 100GBASE-LR4 optics and, if required, enable or confirm support for digital diagnostics to monitor module parameters. After installation, check link status and diagnostics via the host operating system or management interface.

Recommendations

To ensure reliable long-term operation, use clean single-mode LC patch cords, avoid sharp bends in the fiber, and verify compatibility with your hardware platform. If you need to monitor optical parameters remotely, confirm that the host device supports DDM/DOM. For optimal range and performance, install matching LR4-capable transceivers on both ends of the link and follow vendor guidelines for fiber attenuation and connector cleanliness.
