About the DS-SFP-FC32G-LW

The Cisco DS-SFP-FC32G-LW transceiver offers high bandwidth 32 Gigabit Fibre Channel connectivity for metropolitan area storage networks and inter-switch SAN links. Operating at 1310 nanometers, it transmits high throughput storage traffic up to 10 kilometers over standard duplex single mode fibre, supporting NVMe over Fibre Channel replication.

Compatibility

Compatible with Cisco MDS 9132T, MDS 9148T, MDS 9148V, MDS 9396T, and MDS 9396V storage switches. It plugs into SFP28 ports and supports Digital Optical Monitoring through Cisco Data Center Network Manager, Cisco Nexus Dashboard Fabric Controller, and NX-OS CLI environments.

How to identify a genuine unit

Features an SFP28 metallic housing with a blue release latch bail denoting longwave single mode optical transmission. The label lists Cisco branding, part number DS-SFP-FC32G-LW, manufacturing code 10-3143-01, serial number, and hardware engineering revision code.

Buying used

Inspect the optical transceiver bore under magnification to verify cleanliness and check that the mechanical latch locks firmly. Test on a live MDS switch port to confirm that line rate auto-negotiation and optical transmit power metrics register properly.
