## Summary description

CBO QSFP28-100G-CWDM4 is a 100G CWDM4 fiber optic QSFP28 transceiver module designed for high-speed data transmission over single-mode fiber. It supports 100 Gbit/s aggregated bandwidth using four CWDM lanes, suitable for data centers, aggregation links and metro networks. The module enables long-reach connections with low power consumption and hot-pluggable operation for easy installation and maintenance.

## Long description

The Transceiver CBO QSFP28-100G-CWDM4 100G CWDM4 fiber optic QSFP28 module is a compact, hot-pluggable optical transceiver designed for 100 Gbit/s aggregated data transmission over single-mode fiber. Implementing four coarse wavelength-division multiplexing (CWDM) lanes, the module supports high-capacity links for data centers, aggregation and metro networks. Its low power consumption and standardized QSFP28 form factor enable straightforward integration into switches, routers and optical line cards.
Advantages
This QSFP28 CWDM4 transceiver provides long-reach single-mode connectivity with four independent wavelengths, delivering reliable 100 Gbit/s performance. The hot-pluggable design simplifies installation and replacement without system downtime. Optimized for low power consumption and thermal behavior, the module supports dense deployment in rack environments while maintaining compatibility with common QSFP28 ports.
Suitable for
Data centre uplinks and leaf-spine architectures
Aggregation links between switches and routers
Metro and campus long-reach 100G connections
High-density optical interface deployments
Key specifications
Interface: QSFP28 form factor for 100 Gbit/s aggregated link
Optical technology: CWDM4 (four coarse WDM lanes)
Fiber type: single-mode fiber (SMF)
Reach: designed for long-reach single-mode links (metro/data centre spans)
Connector type: compatible with LC duplex connections on corresponding breakout cables or modules
Power: low power consumption optimized for dense deployments
Operation: hot-pluggable for maintenance without powering down host systems
How to use
Install the QSFP28 module into an available QSFP28 slot on a compatible switch, router or optical line card, ensuring correct orientation and firm seating until the module latches. Connect single-mode fiber using appropriate LC-terminated cables or breakout assemblies matching the CWDM4 mapping. After insertion the host system should detect the module and initialize the optical lanes; verify link status and diagnostics via the host management interface. For removal, follow standard hot-swap procedures and handle the module by its housing to avoid touching optical interfaces.
Usage recommendations
Use clean, certified single-mode fiber and LC connectors to maintain signal integrity. Observe manufacturer guidelines for operating temperature and power budgets, and use compatible QSFP28 ports and platform firmware that support CWDM4 modules. When deploying at high density, ensure adequate airflow and consider spare modules for rapid replacement to minimize service disruption.
