About the DS-SFP-FC64G-SW
The Cisco DS-SFP-FC64G-SW transceiver provides high throughput 64 Gigabit Fibre Channel connectivity for next generation storage area networks. Utilizing PAM4 modulation over 850nm multimode fibre, it doubles the bandwidth of 32Gbps links to eliminate storage bottlenecks for all-flash and NVMe over Fibre Channel storage arrays.
Compatibility
Compatible with Cisco MDS 9148V, MDS 9396V, and 64Gbps-capable Cisco MDS switching modules. It provides backward compatibility with 32Gbps and 16Gbps Fibre Channel infrastructure while enabling high density 64Gbps connectivity across enterprise storage fabrics and all-flash arrays.
How to identify a genuine unit
Enclosed in an SFP56 form factor metal casing with a beige or orange release latch bail and a factory label showing part number DS-SFP-FC64G-SW, manufacturing assembly number 10-3330-01, optical classification markers, and authentic Cisco serial identification.
Buying used
Inspect the optical bore for microscopic dust or surface scratching on the optical lenses using a precision fiber microscope. Verify on a 64Gbps MDS switch that NX-OS authenticates the PAM4 transceiver and reports stable optical telemetry without link error accumulation.
Fits these models
Works together
How the Cisco DS-SFP-FC64G-SW connects to servers, storage and the network: 1 way, with the hardware on each path.
Fibre Channel SAN
Match the speed: 16Gb and 32Gb FC HBAs, switches and array ports work together, and each generation also runs one or two speeds below its own (a 32Gb port runs at 16Gb and 8Gb).
