## Summary description

The BlueOptics ONS-QSFP28-LR4-BO is a high-performance QSFP28 network transceiver module designed for fiber optic connections. It features an LC connector and is lightweight at 40g, making it ideal for efficient data transfer over long distances. This module is suitable for various networking applications, ensuring reliable and fast communication.

## Long description

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
Optical standard: 100GBASE-LR4 (CWDM-based Tx/Rx)
Connector: LC duplex optical connector
Fiber type: single-mode fiber
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.
Usage 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.
