DS-CWDM4G1590=

This Cisco transceiver module is built for high-speed Fibre Channel networks, enabling data transfer at 4Gbps over single-mode fiber. It's often found in storage area networks (SANs) where reliable long-distance communication is critical.

Commonly used in data centers and enterprise environments, it supports CWDM wavelengths to maximize fiber infrastructure efficiency. IT professionals deploying or maintaining SANs typically use this module to extend connectivity without sacrificing performance.

Key Features

• Supports 4Gbps Fibre Channel over single-mode fiber up to 40 kilometers
• Utilizes 1590nm wavelength aligning with CWDM standards
• Duplex LC connectors for straightforward fiber cabling
• Hot-swappable SFP design allows easy upgrades and replacements
• Compatible with a range of Cisco networking and storage hardware

This transceiver module is mostly deployed in enterprise data centers and SAN setups where extended fiber runs are necessary. It helps maintain high-speed connectivity between storage arrays and servers, ensuring data moves quickly and reliably across the network.

By using CWDM technology, it also enables multiple wavelengths on the same fiber, optimizing existing fiber infrastructure without adding new cables.
