The Cisco® 100GBASE CFP2 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 CFP2 modules include:

  • Supports 100GBASE Ethernet and OTU3 rates.
  • Hot-swappable input-output device that plugs into an Ethernet CFP2 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, which enables a Cisco switch to identify whether the module is certified and tested by Cisco

Cisco CFP2-100G-ER4

The Cisco 100GBASE-ER4 (Figure 1) CFP2 module can support link lengths up to 40 kilometers on standard duplex single-mode fiber (SMF, G.652) terminated with LC optical connectors. The 100 Gigabit Ethernet signal is carried over four wavelengths. Multiplexing and demultiplexing of the four wavelengths are managed within the device. The Cisco 100GBASE-ER4 CFP2 module meets the IEEE 802.3ba requirements for 100GBASE-ER4 performance and also supports DOM of the transmit-and-receive optical signal levels.

Technical Specifications

Platform Support

Cisco CFP2 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 LC connector.

Note:    Only connections with patch cords with physical contact (PC) or ultraphysical contact (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.

Table 1 provides cabling specifications for the Cisco CFP2 modules.

Table 1.       CFP2 Port Fiber Specifications

Cisco CFP2 Wavelength (nm) Fiber Type Core Size (microns) Modal Bandwidth (MHz-km)*** Max Distance* Digital Optical Monitoring (DOM)
Cisco CFP2-100G-ER4 1310 band
SMF G.652 - 40 km**** Yes

*** Specified at transmission wavelength.

**** Links longer than 30 km for the same link power budget are considered engineered links. Attenuation for such links needs to be less than the worst case specified for single-mode fiber.

Table 2 shows the main optical characteristics.
