    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-24 connectors. It can also be used in 10 x 10 Gigabit Ethernet mode along with ribbon to duplex fiber breakout cables for connectivity to ten 10GBASE-SR optical interfaces. Maximum channel insertion loss allowed is respectively 1.9 dB over 100m of OM3 cable or 1.5 dB over 150m of OM4 cable.

    Cisco CFP-100G-ER4


    The Cisco 100GBASE-ER4 (Figure 3) CFP module can support link lengths up to 40 kilometers on standard duplex single-mode fiber (SMF, G.652) terminated with SC/PC optical connectors. 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 CFP module meets the IEEE 802.3ba requirements for 100GBASE-ER4 performance and also supports Digital Optical Monitoring (DOM) of the transmit-and-receive optical signal levels.

    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 and ER4), 24-fiber MPO/MTP Connector (SR10).


    Note: Only connections with patch cords with physical contact (PC) or ultra physical 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 CFP modules.

    ** Considered an engineered link with maximum 1dB allocated to connectors and splice loss.


    *** 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.
