## Summary description

CBO QSFP28-100G-LR4 is a fiber-optic QSFP28 transceiver module supporting 100G LR4 links. Designed for long-reach single-mode fiber connections, it enables high-speed data transfer between switches, routers and data center equipment. It is used for 100 Gigabit Ethernet or compatible 100G optical interfaces, providing reliable fiber connectivity for network backbones and aggregation links.

## Long description

The Transceiver CBO QSFP28-100G-LR4 Fiber Optic 100G LR4 is a QSFP28 form-factor optical module designed for 100 Gigabit Ethernet over single-mode fiber. It supports LR4 links for long-reach connections and is intended for interconnects between switches, routers and other data centre equipment. The module provides four parallel optical lanes aggregated to a single 100G interface, delivering high-bandwidth connectivity for backbone and aggregation layers.
Advantages
This transceiver offers long-reach single-mode performance with standardized QSFP28 compatibility, allowing straightforward integration into existing 100G ports. It supports low-latency, high-throughput links and is suitable for dense deployments where space and power efficiency are important. The module is hot-pluggable and designed to comply with industry electrical and optical interface specifications for reliable operation in networking environments.

How to use
Install the QSFP28 module into a compatible 100G-capable QSFP28 port on switches, routers or optical equipment according to the host device instructions. Use single-mode fiber patch cords and appropriate LC duplex adapters or MPO-to-LC breakout assemblies as required by the LR4 interface. Ensure correct cable routing, secure connections and verify link status via the network device management interface. Follow manufacturer guidance for handling the optical interface and take electrostatic discharge precautions when inserting or removing the module.
Usage recommendations
For optimal performance, use single-mode fiber infrastructure certified for long-reach LR4 links and maintain clean connectors to minimize optical loss. Verify compatibility with the host device firmware and QSFP28 port settings; if necessary, update device drivers or firmware to support third-party transceivers. Monitor link parameters and perform routine inspections to ensure stable 100G operation.
