About the DS-SFP-FC32G-SW
The Cisco DS-SFP-FC32G-SW is an SFP28 optical transceiver providing 32-Gbps Fibre Channel connectivity over 850nm multimode fibre for Cisco MDS 9000 Series switches. It supports low-latency storage networking, forward error correction, and integrated digital optical diagnostics. It allows high-speed communication between SAN switches, host bus adapters, and all-flash storage arrays.
Compatibility
Fully supported across Cisco MDS 9148T, MDS 9396T, and MDS 9132T fabric switches. The transceiver auto-negotiates to 16Gbps and 8Gbps line rates to ensure smooth integration with existing Fibre Channel host adapters and storage arrays. It functions reliably within Cisco NX-OS without requiring additional configuration commands.
How to identify a genuine unit
Packaged in a hot-pluggable SFP28 housing with an orange or beige extraction bail clasp. The top label displays Cisco product identification DS-SFP-FC32G-SW, version ID, and unique serial number. Querying the transceiver via show interface transceiver in Cisco NX-OS reports authenticated Cisco security encoding and real-time optical metrics.
Buying used
When evaluating used optical transceivers, inspect the optical ports under high magnification to confirm that the LC sleeves are clean. Insert the module into a running MDS switch to confirm that NX-OS recognizes it without third-party module warnings. Verify that the optical receiver power levels match documented factory tolerances.
Fits these models
Works together
How the Cisco DS-SFP-FC32G-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).
