DS-SFP-FC16G-SW Description
DS-SFP-FC16G-SW is a Cisco MDS 9000 Series 16-Gbps Fibre Channel shortwave SFP+ transceiver for short-reach SAN links on supported MDS Fibre Channel ports. It uses a dual LC interface over multimode fiber at 850 nm, supports 4/8/16-Gbps autosensing Fibre Channel operation, and fits LC MMF cabling runs up to 100 m on OM3 or 125 m on OM4/OM5 at 16G, with a 2 m minimum cable distance for qualified links.

Application Scenarios
DS-SFP-FC16G-SW fits Cisco MDS 9000 Fibre Channel ports when the planned path uses LC multimode fiber and the 16G distance stays within Cisco’s documented OM1, OM2, OM3, or OM4/OM5 limits.
Use this part number when the installed link is already built around shortwave MMF optics. A receiving team should keep DS-SFP-FC16G-SW separate from LW and ELW parts because the similar names map to different fiber media and reach.
This optic appears in Cisco MDS transceiver support matrices for multiple MDS switches and modules. Confirm the exact chassis, switching module, and NX-OS release column before the procurement line is released.

- In a DS-SFP-FC16G-SW vs DS-SFP-FC16G-LW comparison, the main difference is fiber media and reach: SW uses 850 nm multimode fiber for short links, while LW uses 1310 nm single-mode fiber for 10 km.
- The DS-SFP-FC16G-SW difference from DS-SFP-FC16GELW is also a media and distance difference. ELW is the 25 km single-mode option, not a shortwave MMF part.
- For buyers comparing which model to choose, keep DS-SFP-FC16G-SW on the order only when the cabling design calls for Cisco 16G Fibre Channel shortwave LC multimode optics.
Selection Guide
1. Match the fiber media before speed
Choose DS-SFP-FC16G-SW when the SAN path uses LC multimode fiber and the installed route fits the Cisco shortwave distance table for the target Fibre Channel rate.
2. Check the 16G distance by fiber grade
At 16G operation, Cisco documents 15 m on OM1, 35 m on OM2, 100 m on OM3, and 125 m on OM4/OM5 for this shortwave part.
3. Do not replace it with a longwave part by name similarity
DS-SFP-FC16G-LW and DS-SFP-FC16GELW share the 16G Fibre Channel SFP+ family, but their single-mode fiber requirements and reach profiles are different from DS-SFP-FC16G-SW.
4. Verify the MDS support matrix
Confirm the MDS platform and NX-OS release support for this exact transceiver before adding the part to a service spare order or expansion quote.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
BOM label |
The requested PID is DS-SFP-FC16G-SW |
Keeps the purchase from drifting to longwave, extended longwave, 8G, or 32G Fibre Channel optics |
|
MDS endpoint |
The receiving port is on a Cisco-supported MDS switch or module |
Ties the optic to a documented SAN platform instead of a generic SFP+ slot |
|
NX-OS table row |
The installed release train lists support for this transceiver |
Keeps maintenance spares aligned with Cisco’s support matrix |
|
Patch plant |
The route uses LC multimode fiber with the required OM grade |
Confirms the shortwave optic matches the existing MMF cabling |
|
Optical span |
The route is at least 2 m and within the distance for the operating rate |
Prevents a 16G shortwave link from exceeding the Cisco cable table |
|
Remote end |
The opposite side uses a compatible 16G shortwave Fibre Channel optic |
Reduces install risk from wavelength or media mismatch |
