## Summary description

CBO QSFP28-100G-LR4-VA-BO is a fiber optic QSFP28 transceiver supporting 100 Gbit/s data rate with LR4 specification for long-reach single-mode links up to 10,000 m. Designed for high-capacity network uplinks and data center interconnects, it provides reliable optical transmission for backbone, metro and long-distance applications, simplifying upgrades to 100G infrastructure.

## Long description

CBO QSFP28-100G-LR4-VA-BO is a fiber optic QSFP28 transceiver module that supports a 100 Gbps data rate with LR4 specification for long-reach single-mode connections up to 10,000 m. Intended for use in high-capacity network uplinks, data center interconnects and long-distance optical links, the module provides standard-compliant optical transmission in a compact QSFP28 form factor and facilitates migration to 100G infrastructure.
Advantages
The transceiver uses LR4 optics optimized for single-mode fiber to deliver 100 Gbps over extended distances, reducing the need for intermediate repeaters. Its QSFP28 form factor supports high port density and hot-pluggable installation, allowing easy replacement and upgrades without powering down connected equipment. The module is manufactured to industry interoperability standards for predictable performance with compatible switches, routers and multiplexing equipment.
Suitable for
 Data center interconnects and spine-to-spine links
 Metro and regional backbone connections
 Long-distance single-mode fiber links up to 10 km
 Network infrastructure upgrades to 100 Gbps
Key specifications
 Form factor: QSFP28
 Data rate: 100 Gbps
 Optical specification: LR4 (four-channel long reach)
 Fiber type: single-mode fiber (SMF)
 Maximum link length: up to 10,000 m (10 km) on SMF
 Connector interface: duplex LC with appropriate breakout or MUX/DEMUX
 Power consumption: typical for QSFP28 LR4-class modules (refer to device datasheet for exact values)
How to use
Ensure the host device supports QSFP28 LR4 modules and that firmware permits third-party transceivers if applicable. Insert the transceiver into a compatible QSFP28 port until it seats and latches; the module is hot-pluggable and can be installed while the system is powered. Connect single-mode fiber using appropriate LC connectors and confirm correct polarity. Validate link status and data rate on the host device; perform optical power and BER checks if required for installation acceptance.
Usage recommendations
Handle the transceiver using ESD precautions and keep dust caps on fiber interfaces when not connected. Match the module to single-mode fiber plants with proper attenuation and dispersion budgets for 10 km links. For best results, verify compatibility with the switch or router vendor and check optical power levels and diagnostics via the host's monitoring tools.
