Product Overview

The Cisco® 100GBASE CFP modules offer customers 100 Gigabit Ethernet connectivity options for data center networking, enterprise core aggregation, and service provider transport applications.

Features and Benefits

Main features of Cisco 100GBASE CFP modules include:

Supports 100GBASE Ethernet

Hot-swappable input/output device that plugs into an Ethernet CFP port of a Cisco switch or router

Provides flexibility of interface choice

Supports “pay-as-you-populate” model

Supports digital optical monitoring (DOM)

Supports the Cisco quality identification (ID) feature that enables a Cisco switch to identify whether the module is certified and tested by Cisco

Cisco CFP-100G-LR4

The Cisco 100GBASE-LR4 (Figure 1) CFP module supports a link length of 10 kilometers on standard single-mode fiber (SMF, G.652). 100 Gigabit Ethernet signal is carried over four wavelengths. Multiplexing and demultiplexing of the four wavelengths are managed within the device.

Cisco CFP-100G-SR10

The Cisco 100GBASE-SR10 (Figure 2) CFP module supports link lengths of 100 meters and 150 meters respectively on laser-optimized OM3 and OM4 multifiber cables. It primarily enables high-bandwidth 100-Gigabit links over 24-fiber ribbon cables terminated with MPO/MTP connectors. It can also be used in 10x10G mode along with ribbon to duplex fiber breakout cables for connectivity to ten 10GBASE-SR optical interfaces. Maximum channel insertion loss allowed is respectively 1.9dB over 100m of OM3 cable or 1.5dB over 150m of OM4 cable.

Technical Specifications

Platform Support

Cisco CFP modules are supported on Cisco switches and routers. For more details, refer to the document “Cisco 100-Gigabit Ethernet Transceiver Modules Compatibility Matrix.”

Connectors and Cabling

Connectors: Dual SC/PC Connector (-LR4), 24-fiber MPO/MTP Connector (-SR10).

Note: Only connections with patch cords with PC or UPC connectors are supported. Patch cords with APC connectors are not supported. All cables and cable assemblies used must be compliant with the standards specified in the standards section.
