Product Summary:
Cisco DS-SFP-FC16G series Fibre Channel transceivers deliver high-performance, low-latency 16Gbps connectivity for SAN environments. The DS-SFP-FC16G-SW is optimized for shortwave (SW) multi-mode fiber, while the DS-SFP-FC16G-LW is designed for longwave (LW) single-mode fiber, enabling flexible deployment across different distances and infrastructure types.
Product Description:
The DS-SFP-FC16G-SW and DS-SFP-FC16G-LW are next-generation Fibre Channel SFP+ transceiver modules developed by Cisco. These modules support 16 Gbps line rate and are backward compatible with 8 Gbps and 4 Gbps Fibre Channel speeds, providing scalability and investment protection.
DS-SFP-FC16G-SW operates over multi-mode fiber (MMF) at 850 nm and supports distances up to 100 meters (OM4).
DS-SFP-FC16G-LW operates over single-mode fiber (SMF) at 1310 nm and reaches up to 10 kilometers, ideal for data center interconnects and enterprise SAN links.
Both transceivers are hot-swappable, digital optical monitoring (DOM) capable, and fully compatible with Cisco MDS and Nexus SAN switching platforms.
