CBO Transceptor QSFP28-100G-CWDM4 Módulo de fibra óptica 100G CWDM4

The CBO Transceiver QSFP28-100G-CWDM4 100G CWDM4 fiber optic module is a QSFP28-form-factor transceiver designed for 100 Gigabit Ethernet links using coarse wavelength division multiplexing (CWDM4). It provides a compact, hot-pluggable solution for high-density switch-to-switch, switch-to-router and router-to-router interconnects in data centers and telecom environments. The module supports 100G transmission over single-mode fiber across the CWDM4 wavelength channels, enabling simplified cabling and efficient use of existing fiber infrastructure.

Advantages

The module offers a high port density and low power consumption in a QSFP28 package, allowing network operators to increase bandwidth without extensive physical space or cooling requirements. Its CWDM4 wavelength approach reduces the number of fibers required for 100G links compared with parallel optics while maintaining performance over typical data center distances. The transceiver is hot-pluggable and compatible with standard QSFP28 cages, facilitating straightforward installation and replacement.

Suitable for

• High-speed data center interconnects between switches and routers
• Aggregation and spine-leaf network fabrics
• Telecom and carrier transport links within campus or metro networks
• Upgrading existing single-mode fiber infrastructure to 100G

Key specifications

• Form factor: QSFP28 (4-channel, electrical interface for 100G)
• Data rate: 100 Gigabit Ethernet
• Optical modulation: CWDM4 wavelength multiplexing
• Fiber type: single-mode fiber compatibility for CWDM4 channels
• Connector type: standard fiber optic duplex/MP-style adapter compatibility as per CWDM4 implementations
• Reach: suitable for typical data center and metro distances as defined for CWDM4 links
• Power: low-power QSFP28-class module suitable for high-density applications

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port until it latches, taking electrostatic discharge (ESD) precautions when handling the module. Connect appropriate single-mode fiber patch cords to the module using matching connectors and ensure the correct CWDM4 channel mapping if using an MTP/MP-style breakout or duplex arrangement. Verify link status through the host device management interface and monitor signal diagnostics if supported. For removal, disengage the latch and gently extract the module while observing ESD safety.

Recommendations

Use factory-tested single-mode fiber and maintain clean connector endfaces to ensure optimal optical performance. Confirm compatibility with the switch or router vendor for QSFP28 optical modules and verify supported link distances for your specific deployment. Store unused modules in protective packaging to avoid contamination and mechanical damage.
