Transceiver CBO QSFP28-100G-LR4 BO28L13610D Fiber Optic 100G LR4

The Transceiver CBO QSFP28-100G-LR4 BO28L13610D Fiber Optic 100G LR4 is a single-mode QSFP28 module engineered for 100 Gbps LR4 links. It provides long-reach optical transmission over single-mode fiber and is compatible with QSFP28 form-factor ports in high-density switches and routers. The module is intended for use in environments that require reliable 100G connectivity between data center equipment or across campus backbone connections.

Advantages

This QSFP28 LR4 transceiver supports 100 Gbps aggregated bandwidth using four lanes and is optimized for long-reach single-mode fiber links. Its QSFP28 form factor enables high port density in modern network switches and routers, and the module is designed for interoperability with standard QSFP28 interfaces. Built for continuous operation in networking environments, it offers a deterministic physical interface for 100G uplinks and backbone interconnects.

Suitable for

• Data center uplinks between aggregation and spine switches
• Campus backbone links requiring 100G single-mode transmission
• High-density network equipment in enterprise and carrier environments
• Optical links that require LR4 long-reach single-mode performance

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port on the host device while the device is powered or according to the host's hot-plug guidelines. Connect appropriate single-mode fiber patch cables to the module's optical interface in accordance with LR4 polarity and LC connector conventions used by the equipment. Verify link status and diagnostics through the host equipment's management interface and monitor optical power and alarm indicators to confirm proper operation.

Recommendations

Use factory-tested single-mode LC patch cables and follow the host vendor's compatibility list when selecting modules for mission-critical links. Ensure fiber cleanliness and correct connector polarity before insertion. For long-haul runs, verify optical budget and dispersion limits and monitor transceiver diagnostics for optical power, temperature, and receiver sensitivity.
