CBO QSFP28 100G CWDM4 Módulo transceptor – 100 Gb/s ótico CWDM4 QSFP28

CBO QSFP28-100G-CWDM4 is a QSFP28 form-factor optical transceiver engineered to deliver 100 Gb/s data transmission over single-mode fiber using CWDM4 wavelength division multiplexing. The module is designed for short-to-medium reach fiber links in data centers and campus networks, offering interoperable 100G connectivity for compatible switches, routers and aggregation equipment. It enables port upgrades to 100G, extension of existing fiber links and simplified high-bandwidth aggregation with a compact, hot-pluggable design.

Advantages

The QSFP28 CWDM4 transceiver supports 100 Gb/s throughput while maintaining low power consumption and compact QSFP28 housing for high-density deployments. It uses CWDM4 multiplexing to enable four-wavelength transmission over single-mode fiber, which reduces the need for parallel fiber cabling. The module is built to industry optical interfaces and is suitable for plug-and-play installation with standard 100G ports, offering predictable optical performance and stable link operation for short-to-medium reach connections.

Suitable for

• 100G uplinks between switches and aggregation devices in data centers
• Short-to-medium reach single-mode fiber links up to typical CWDM4 distances
• Upgrading existing ports to 100G capacity without changing fiber plant topology
• High-density rack deployments where QSFP28 form factor is required

Key specifications

How to use

Install the transceiver into a compatible QSFP28 port on your switch, router or other networking equipment while the host port is powered. Connect the module to single-mode fiber using an appropriate duplex LC patch cable and verify the link status through the host device management interface. Configure the host port for 100G operation if required by your equipment, and monitor optical parameters such as receive/transmit power and link alarms using the host's diagnostics. Follow equipment vendor guidance for SFP/QSFP compatibility lists and allowable optical loss budgets.

Recommendations

Use this CWDM4 QSFP28 transceiver in environments with controlled bend radii and clean connector end-faces. For stable performance, ensure fiber patch panels and cabling meet single-mode and CWDM specifications and test end-to-end loss before production deployment.
