The c stands for the Latin letter C used to express the number 100 (centum), since the standard was primarily developed for 100 Gigabit Ethernet systems.

While the electrical connection of a CFP uses 10 \u00d7 10 Gbit\/s lanes in each direction (RX, TX),[1] the optical connection can support both 10 \u00d7 10 Gbit\/s and 4 \u00d7 25 Gbit\/s variants of 100\u00a0Gbit\/s interconnects (typically referred to as 100GBASE-SR10 in 100\u00a0meter MMF, 100GBASE-LR10 and 100GBASE-LR4 in 10\u00a0km SMF reach, and 100GBASE-ER10 and 100GBASE-ER4 in 40\u00a0km SMF reach respectively.)[3]In March 2009, Santur Corporation demonstrated a 100\u00a0Gigabit pluggable CFP transceiver prototype.[4]Supported signals[edit]Digital[edit]CFP transceivers can support a single 100\u00a0Gbit\/s signal like 100GbE or OTU4 or one or more 40\u00a0Gbit\/s signals like 40GbE, OTU3, or STM-256\/OC-768. Analog[edit]The Optical Internetworking Forum in 2016 published the CFP2-ACO or CFP2 – Analog Coherent Optics Module Interoperability Agreement (IA). This IA supports a configuration where the digital signal processor (DSP) is on the main board and analog optical components are on the module. This IA is useful in the case when the DSP exceeds the module power envelope.[5]The ACO interface can be used in coherent optics applications when the link delivers a flexible amount of bandwidth to the system, for example when combined with FlexE. The initial ACO IA is for the CFP2 module.Variants[edit]The original CFP specification was proposed at a time when 10\u00a0Gbit\/s signals were far more achievable than 25\u00a0Gbit\/s signals. As such to achieve 100\u00a0Gbit\/s line rate, the most affordable solution was based on 10 lanes of 10\u00a0Gbit\/s. However, as expected, improvements in technology have allowed higher performance and higher density. Hence the development of the CFP2 and CFP4 specifications. While electrically similar, they specify a form-factor of 1\/2 and 1\/4 respectively in size of the original specification. Note that CFP, CFP2 and CFP4 modules are not interchangeable (but are inter-operable at the optical interface with appropriate connectors).CFP[edit]82\u00a0mm \u00d7 13.6\u00a0mm \u00d7 144.8\u00a0mm (width\u00d7height\u00d7depth)148 pin electrical connectionintegrated digital signal processor within packageless than 24 W power usage10\u00d710G or 4\u00d725G lanes[1]CFP2[edit]41.5\u00a0mm \u00d7 12.4\u00a0mm \u00d7 107.5\u00a0mm (w\u00d7h\u00d7d)104 pin electrical connectionno digital signal processor in package, relies on host cardless than 12 W power usage10\u00d710G, 4\u00d725G, 8\u00d725G, or 8\u00d750G lanes [6]Analog Coherent OpticsCFP4[edit]21.5\u00a0mm \u00d7 9.5\u00a0mm \u00d7 92\u00a0mm (w\u00d7h\u00d7d)56 pin electrical connectionno digital signal processor in package, relies on host cardless than 6 W power usage4\u00d710G or 4\u00d725G lanes [7]CFP8[edit]40\u00a0mm \u00d7 9.5\u00a0mm \u00d7 102\u00a0mm (w\u00d7h\u00d7d)124 pin electrical connectionno digital signal processor in package, relies on host cardmax. 24 W power usage16\u00d725G lanes (25.78125 or 26.5625 GBd) or 8\u00d750G lanes [8]MSA 5\u2033\u00d77\u2033 (Gen 1)[edit]168 pin electrical connection (designed to be built into a line card)digital signal processor within packageless than 80 W power usage [9][10]MSA 4\u2033\u00d75\u2033 (Gen 2)[edit]168 pin electrical connection (designed to be built into a line card)digital signal processor within packageless than 40 W power usageSee also[edit]References[edit]External links[edit]"},{"@context":"http:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki12\/#breadcrumbitem","name":"Enzyklop\u00e4die"}},{"@type":"ListItem","position":2,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki12\/c-form-factor-pluggable-wikipedia\/#breadcrumbitem","name":"C form-factor pluggable – Wikipedia"}}]}]
