Transceiver CBO QSFP28-100G-CWDM4 glasvezel 100G CWDM4-module

CBO QSFP28-100G-CWDM4 Fiber Optic 100G CWDM4 module is a hot-pluggable QSFP28 transceiver designed for 100 gigabit CWDM4 links. It implements coarse wavelength-division multiplexing over four wavelengths to carry 100G Ethernet signals using MPO/MTP multimode fiber connectors, offering a compact form factor suitable for high-density data center and metro applications. The module supports interoperability with standard QSFP28 ports to enable straightforward bandwidth upgrades and connections between switches, routers and optical transport equipment.

Advantages

The transceiver delivers a compact QSFP28 form factor that saves rack and switch port space while enabling 100G connectivity. Hot-pluggable design allows installation or replacement without powering down systems, reducing maintenance windows. CWDM4 wavelength multiplexing provides an efficient and cost-effective method for extending 100G links over duplex multimode fiber trunks with MPO/MTP connectivity. Built for interoperability, the module integrates with common networking hardware to simplify capacity upgrades.

Suitable for

• High-density data center uplinks and spine switches
• Metro aggregation links and campus backbone connections
• Inter-switch and switch-to-router 100G links
• Optical transport equipment requiring QSFP28 CWDM4 interfaces
