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

The Transceiver CBO QSFP28-100G-CWDM4 Fiber Optic 100G CWDM4 module is a QSFP28 form-factor optical transceiver designed for 100 Gigabit Ethernet links using coarse wavelength-division multiplexing (CWDM4). It provides 100G connectivity over four CWDM wavelengths, enabling high-bandwidth point-to-point connections between compatible switches, routers and optical equipment. The module is intended for use in data center interconnects, aggregation and backbone links where reliable, high-speed optical transmission is required.

Advantages

This CWDM4 QSFP28 transceiver offers compact QSFP28 sizing with 100G capacity and lower power consumption compared with multiple parallel modules. It supports long-reach transmission appropriate for typical data center spans and offers interoperability with equipment that accepts QSFP28 CWDM4 optics. The module simplifies network design by providing single-lane 100G optical connectivity over standardized wavelengths, reducing fiber complexity and easing installation and maintenance.

Suitable for

• Data center interconnects between racks or buildings
• Aggregation and spine-to-leaf links in high-density networks
• 100 Gigabit backbone segments and campus core links
• Optical upgrades where existing fiber plant supports CWDM wavelengths

Key specifications

• Form factor: QSFP28
• Link speed: 100 Gigabit Ethernet
• Wavelengths: CWDM4 (four CWDM channels)
• Optical interface: duplex LC or MPO depending on platform compatibility (verify port type)
• Reach: designed for typical data center CWDM4 reach (check equipment and fiber plant for exact distance support)
• Power consumption: low-power QSFP28 class module suitable for high-density deployments
• Operating temperature range: suitable for standard equipment operating conditions

How to use

Install the QSFP28 module into a compatible QSFP28 port on networking equipment following standard hot-plug procedures. Ensure the host device supports 100G CWDM4 optics and that the fiber cabling and connector type match the module’s optical interface. After insertion, confirm link status and transceiver diagnostics through the host device management interface. Use proper ESD precautions and remove dust caps from fiber connectors before mating to avoid signal degradation.

Recommendations

Verify compatibility with the target switch or router model and confirm the required optical connector type and fiber plant suitability for CWDM wavelengths. Maintain clean connectors, monitor transceiver diagnostics for temperature and optical power parameters, and follow vendor guidelines for handling and installation to ensure stable 100G links.
