Cisco Nexus 3550-F Data Demultiplexer

A flexible low latency networking platform

The Cisco Nexus^® 3550-F products are a compact yet powerful networking platform designed specifically for low-latency applications. The Nexus 3550-F products feature up to 48 ports of 10G Ethernet connectivity in a single-rack-unit form factor that can be configured as follows:

• Cisco Nexus 3550-F Modular Layer 1 Matrix Switch is purpose-built for low-latency data fan-out, electronic patch panels, and transparent monitoring applications. Layer 1 switching offers port-to-port latencies under 5ns.


• Cisco Nexus 3550-F Programmable Multiplexer Switch is designed to support multiple multiplexing modes for many-to-one aggregation use cases. Applications include low-latency link aggregation for financial trading order entry networks and low-latency telecommunications networks. This mode offers latencies as low as 39ns.

Scalable modular architecture

The Cisco Nexus 3550-F products are built with a unique modular architecture that scales with your network. Three-line card bays provide the flexibility to grow and change connectivity options over time, while two internal module bays allow the device to be upgraded with expanded functionality, adding new capabilities and extending the useful life of the product. The 3550-F architecture is shown in the figure below. At the heart of the architecture is a high-density Layer 1 matrix switch. This matrix switch provides low-latency programmable 10GbE connectivity between all modules.
