Fiber optic transceiver module BlueOptics F5-UPG-QSFP28-LR4-BO QSFP28 MPO

The BlueOptics F5-UPG-QSFP28-LR4-BO QSFP28 MPO is a fiber optic transceiver module designed for 100G long-range data transmission over single-mode fiber. It uses a QSFP28 electrical interface with an MPO optical connector and is intended for installation in compatible networking equipment. The compact, lightweight silver module supports standard MSA mechanical and electrical specifications and includes digital diagnostics monitoring for real-time parameter reporting.

Advantages

This QSFP28 MPO transceiver supports 100GBASE-LR4 applications and is compatible with hardware that accepts QSFP28 modules following MSA standards. It combines long-range capability with a small form factor and low weight, enabling dense port deployment in data center and enterprise network environments. Integrated digital diagnostics (DDM/DOM) provide real-time monitoring of temperature, supply voltage, laser bias current and optical power to assist with maintenance and troubleshooting.

Suitable for

• 100G Ethernet links in data centers and core networks
• Long-range single-mode fiber connections up to typical LR4 distances
• High-density switch, router, or load balancer QSFP28 ports
• Applications requiring optical link monitoring via DDM/DOM

How to use

Install the BlueOptics QSFP28 MPO module into a compatible QSFP28 port following the host equipment manufacturer’s hot-plug procedures. Ensure the device firmware supports third-party QSFP28 transceivers and that the receiving equipment is configured for 100GBASE-LR4 operation. Connect single-mode MPO patch cords or appropriate breakout cables to match the LR4 wavelength lanes and verify link status. Use the module's DDM/DOM outputs via the host to monitor operating parameters and confirm correct optical power and temperature ranges.

Recommendations

For optimal performance, pair the transceiver with single-mode MPO patch cords and, where required, LC breakout assemblies that match the LR4 lane configuration. Confirm host compatibility and enable DDM/DOM monitoring in the network management system. Observe ESD precautions during handling and follow manufacturer guidance for insertion and removal to avoid damage to the module or connector endfaces.
