Transceptor CBO QSFP28-100G-CWDM4 fibra ótica módulo 100G

The Transceiver CBO QSFP28-100G-CWDM4 Fiber Optic 100G module is a compact QSFP28 form-factor transceiver for 100 Gigabit Ethernet links. It implements CWDM4 optics to carry four coarse wavelength-division multiplexed channels, enabling 100G connectivity over appropriate single-mode fiber spans. Designed for datacenter interconnects, switch and router uplinks, the module supports short to medium reach CWDM4 applications and fits into standard QSFP28 ports for straightforward integration into existing network equipment.

Advantages

The module provides dense 100G transmission in a small QSFP28 package, allowing high port density in racks and chassis. CWDM4 technology reduces fiber and transceiver cost versus parallel optics for comparable distances. The transceiver is hot-pluggable, enabling maintenance and upgrades without powering down systems, and its compliance with common QSFP28 mechanical and electrical specifications ensures broad interoperability with compatible switches and routers.

Suitable for

• Data center spine-to-leaf interconnects and server uplinks
• Switch-to-switch and router-to-router 100G links
• Short to medium reach single-mode fiber connections using CWDM4
• High-density networking deployments requiring QSFP28 form factor

Key specifications

• Form factor: QSFP28
• Data rate: 100 Gigabit Ethernet
• Optical technology: CWDM4 (four coarse WDM channels)
• Fiber type: single-mode fiber (SMF) optimized for CWDM4
• Reach: designed for CWDM4 short to medium distance links (per CWDM4 application guidelines)
• Connector interface: QSFP28 electrical/mating connector for standardized cage and port

How to use

Install the transceiver into a compatible QSFP28 port on a switch, router or network appliance until it seats securely. Connect a suitable single-mode fiber cable with compatible LC or specified CWDM4 breakout/pigtail assemblies as required for the link. Verify link negotiation and 100G operation via the host device management interface and monitor signal status using available diagnostics. To prevent damage, handle the optical interfaces with protective caps when not connected and observe electrostatic discharge precautions when inserting or removing the module.

Recommendations

Choose single-mode fiber and CWDM4-compatible cabling assemblies that match the intended link distance, and confirm interoperability with the host equipment vendor. For reliable operation, keep transceiver firmware and device drivers up to date and perform optical power budget checks during installation.
