Description
The Cisco DS-SFP-FC4G-SW is a hot-swappable, Small Form-Factor Pluggable (SFP) transceiver module designed for shortwave Fibre Channel connectivity in data center and enterprise network environments. Built to support 4 Gbps Fibre Channel speeds, it is backward-compatible with 2 Gbps and 1 Gbps systems, making it a flexible choice for mixed-speed networks. This transceiver operates over multimode fiber (MMF) and supports distances of up to 500 meters using 50/125 µm MMF, ideal for short-range, high-speed data transfers. Its compact design allows for high port density, helping maximize space and scalability in SAN switches and directors.
This model features an LC duplex connector and complies with industry-standard SFP MSA and Fibre Channel specifications, ensuring compatibility with a wide range of Cisco MDS-series switches and other networking equipment. The DS-SFP-FC4G-SW includes digital optical monitoring (DOM) support, enabling real-time monitoring of critical parameters such as optical power, temperature, and voltage. Designed with durability and performance in mind, it’s a reliable option for upgrading or expanding existing Fibre Channel infrastructures. When purchasing used, buyers benefit from cost savings while still acquiring a dependable, enterprise-grade component that meets demanding data storage and transmission requirements.
