## Summary description

Compatible BlueOptics AV1E-BO QSFP28 100GBASE-LR4 optical transceiver for singlemode fiber with LC-duplex connector. Supports 4xWDM wavelengths, 10 km reach and diagnostic monitoring (DDM/DOM). Designed for 100 Gbps links in data center and carrier networks, suitable for long-reach uplinks and metro/backbone connections.

## Long description

BlueOptics AV1E-BO QSFP28 100GBASE-LR4 is an optical transceiver module designed for 100 Gbps singlemode fiber links with LC-duplex termination. The module implements 4xWDM (four wavelengths) to carry 100 Gbps over a single fiber pair and supports a link reach of up to 10 km. Built for deployment in data center uplinks, carrier metro and backbone networks, this transceiver offers Digital Diagnostic Monitoring (DDM/DOM) to report optical and electrical parameters for real-time link health checks.
Advantages
This QSFP28 transceiver offers high-density 100G connectivity in a compact QSFP28 form factor, enabling efficient use of switch and router ports. The LR4 optical design extends link reach to 10 km on singlemode fiber, allowing use in longer intra- and inter-site connections. Integrated diagnostic monitoring provides access to key operating metrics such as optical power and temperature, facilitating troubleshooting and proactive maintenance. The LC-duplex interface supports common fiber cabling systems and simplifies integration into existing singlemode networks.
Suitable for
Data center uplinks and leaf-spine fabrics requiring 100G aggregation
Carrier metro and backbone connections up to 10 km
Inter-site links between campus or building locations
Network equipment with QSFP28 ports supporting 100GBASE-LR4

How to use
Install the transceiver into a compatible QSFP28 port on a switch, router or media converter, ensuring the host device supports 100GBASE-LR4 optics. Connect LC-duplex singlemode patch cords to the module and the remote device, observing correct polarity. After insertion, verify link status and monitor diagnostic parameters via the host device management interface to confirm optical power levels and module temperature are within expected ranges. If necessary, adjust link budget or replace patch cords to correct signal issues.
Usage recommendations
Use high-quality singlemode LC patch cords and maintain clean connector endfaces to ensure reliable 100G links. Confirm compatibility with the host device firmware and QSFP28 port specifications before deployment. Monitor DDM/DOM values regularly to detect degradation early and plan maintenance to avoid unexpected outages.
