16Gb Fibre Channel Shortwave Optics

The DS-SFP-FC16G-SW is designed for short-distance Fibre Channel connections within data centers and storage environments. Its 850nm shortwave optical interface is optimized for multimode fiber infrastructure.

Cisco specifies a nominal 14.025GBd rate for 16Gbps Fibre Channel and supports backward operation at 8.5GBd and 4.25GBd. :contentReference[oaicite:2]{index=2}

Multimode Fiber Connectivity

The transceiver uses multimode fiber rather than single-mode fiber. Cisco specifies compatibility with 62.5µm OM1 and 50µm OM2, OM3 and OM4/OM5 fiber types.

The maximum distance varies substantially with both fiber grade and Fibre Channel speed, so the fiber type should always be considered when planning a storage-network link.

Supported Fiber Distances

These distances are Cisco's published cabling specifications for the DS-SFP-FC16G-SW. :contentReference[oaicite:3]{index=3}

Duplex LC Connector

The Cisco DS-SFP-FC16G-SW uses dual LC optical connectors. One fiber carries the transmit signal and the second fiber carries the receive signal.

Duplex LC multimode fiber is widely used in data center Fibre Channel SAN environments, making the module suitable for existing Cisco MDS storage-fabric cabling.

Autosensing 4/8/16Gb Fibre Channel

The DS-SFP-FC16G-SW supports 4Gbps, 8Gbps and 16Gbps Fibre Channel operation. Cisco describes its 16Gb Fibre Channel SFP+ transceivers as providing 4/8/16Gbps autosensing connectivity. :contentReference[oaicite:4]{index=4}

This makes the module useful in SAN environments where equipment may operate at different Fibre Channel generations, provided the host platform and connected devices support the desired speed.

Optical Performance

For 16Gbps operation, Cisco specifies average transmit power from approximately -7.8dBm to -1.3dBm and average receive power from approximately -10.3dBm to 0dBm. The specified fiber-loss budget varies by fiber type and speed. :contentReference[oaicite:5]{index=5}

For a 16Gbps link, the published fiber-loss budget is approximately 1.63dB on OM1/OM2, 1.86dB on OM3 and 1.86dB on OM4/OM5 under the applicable Cisco specifications. :contentReference[oaicite:6]{index=6}

Fibre Channel SAN Applications

• Cisco MDS Fibre Channel switches
• Storage Area Networks (SAN)
• Fibre Channel switch-to-switch links
• Server-to-SAN connectivity
• Storage array connectivity
• Data center storage fabrics
• Backup and replication networks
• Enterprise storage infrastructure
• High-availability SAN environments
• Virtualized storage networks

DS-SFP-FC16G-SW vs DS-SFP-FC16G-LW

The SW version is designed for multimode-fiber shortwave applications, while the LW version is intended for longer-distance single-mode fiber connections. Cisco specifies up to 10km for the DS-SFP-FC16G-LW. :contentReference[oaicite:7]{index=7}

Compatibility

Cisco identifies the DS-SFP-FC16G-SW as a Fibre Channel SFP+ transceiver for Cisco MDS 9000 Series platforms. It provides 4/8/16Gbps Fibre Channel connectivity where supported by the host platform. :contentReference[oaicite:8]{index=8}

Cisco's troubleshooting documentation also identifies the module by PID DS-SFP-FC16G-SW and confirms support for speeds from 4Gbps through 16Gbps. :contentReference[oaicite:9]{index=9}

Always verify the exact Cisco MDS switch, line card and software release before purchasing, particularly when replacing an existing Fibre Channel optic.
