Transceptor CBO QSFP28-100G-CWDM4 100G CWDM4 QSFP28 módulo óptico

Transceiver CBO QSFP28-100G-CWDM4 100G CWDM4 QSFP28 optical module is a 100G CWDM4 QSFP28 transceiver designed for high‑speed fiber optic links. The module supports 100 Gigabit Ethernet over four coarse WDM wavelengths in a compact QSFP28 form factor, enabling aggregation and interconnect links in data center and enterprise network environments. It is intended for straightforward replacement in QSFP28 ports that accept CWDM4 optics and for adding 100G connectivity on short- to medium-reach single-mode fiber runs.

Advantages

The module provides four-wavelength CWDM operation in a standardized QSFP28 package, offering a combination of high bandwidth and compact density. It supports 100G transmission with low power consumption relative to equivalent single-lambda solutions, and its hot-pluggable QSFP28 form factor simplifies installation and maintenance. Built for compatibility with typical QSFP28 interfaces, the transceiver enables predictable performance for aggregation and interconnect tasks without requiring major hardware changes.

Suitable for

• 100 Gigabit Ethernet links between QSFP28 ports in data centers
• Aggregation and spine-leaf interconnects on single-mode fiber
• Short- to medium-reach campus or enterprise fiber runs
• Replacement or upgrade of existing CWDM4-capable QSFP28 ports

Key specifications

• Form factor: QSFP28
• Data rate: 100 Gbps aggregate (CWDM4)
• Fiber type: Single-mode fiber
• Wavelength: CWDM4 four-channel coarse WDM
• Reach: short- to medium-reach single-mode links (vendor-specific distances)
• Connector type: LC duplex (typically for CWDM4 QSFP28)
• Power consumption: low-power QSFP28 class (typical values depend on implementation)

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port until it seats securely, following equipment vendor instructions for hot-plug handling. Connect single-mode LC duplex fiber patch cords between corresponding ports, ensuring correct orientation and clean connectors to maintain optical performance. Configure link settings on connected switches or routers as required for 100 Gigabit Ethernet, and verify link status and diagnostics through the host device management interface. If the host requires specific vendor support, confirm compatibility before deployment.

Recommendations

To ensure reliable performance, use high-quality single-mode fiber and LC connectors, inspect and clean connectors before mating, and follow the switch or router vendor guidance for CWDM4 optics. Monitor optical power and link diagnostics after installation, and replace the module in a controlled maintenance window if any interoperability or performance issues appear.
