The Cisco DS-SFP-FC32G-SW is a new, genuine 32 Gbps Fibre Channel Shortwave (SW) SFP+ transceiver module designed for the Cisco MDS 9000 Family platforms. Buying this new module ensures you receive the latest, fully warranted hardware revision, guaranteeing maximum reliability and compatibility for your critical Storage Area Network (SAN) infrastructure. This hot-pluggable module provides essential connectivity for high-speed data center interconnections. The DS-SFP-FC32G-SW is a multi-rate module, supporting autosensing Fibre Channel speeds of 8.5 Gbps, 14.025 Gbps, and 28.05 Gbps, corresponding to 8GFC, 16GFC, and 32GFC operations respectively. This backward compatibility protects your investment while offering a clear path to the highest bandwidth 32G Fibre Channel speeds. It operates at an 850nm wavelength and utilizes Duplex LC connectors for connectivity over Multi-Mode Fiber (MMF). When used with OM4 fiber, it can achieve a maximum distance of 100 meters at 32 Gbps, or 70 meters with OM3 fiber. This shortwave capability makes it the perfect choice for high-density, short-to-medium reach links typically found within a single data center or server rack. The module includes Digital Optical Monitoring (DOM) support, which provides real-time diagnostic information such as temperature, transmit power, and receive power, allowing network administrators to ensure optimal link performance and quickly diagnose any potential issues. Its compact SFP+ form factor allows for high-density deployment in director switching modules and fabric switch ports, ensuring efficient use of space and simplified port management.
