The latest in the CFP module line, the 100G CFP4 form factor represents the most efficient port usage of the CFP line and comes in a variety of 100G capable transceiver modules with varying specifications, including CFP4-ER4L, CFP4-LR4 and CFP4M-ER4L. CFP4 is a 4 times smaller version of CFP. This optical transceiver supports data rates up to 111 Gbps and fits CFP2 port of any brand of equipment. Skylane Optics offers a limited range of CFP2 transceivers with an unique set of services, such as testing, coding, customization, effective support &. A CFP optical module is a high-speed pluggable transceiver used in fiber optic communication systems to enable 100 Gigabit Ethernet (100G) data transmission over optical fiber. It plays a fundamental role in converting electrical signals from networking equipment into optical signals—and vice. This article breaks down the key differences between CFP, CFP2, CFP4, and CFP8 optical transceivers commonly used in fiber optic networks. Figure 1: Dimensions of CFP, CFP2, CFP4, and CFP8 The table below summarizes the specifications of each form factor: 24 W (Max. ) In essence, the progression. The FS® 100GBASE Quad Small Form-Factor Pluggable (CFP/CFP2/CFP4/CXP) portfolio offers customers a wide variety of high-density and low-power 100 Gigabit Ethernet connectivity options for data center, high-performance computing networks, enterprise core and distribution layers, and service provider. The CFP standard defines a pluggable optical transceiver form factor capable of supporting 40G and 100G Ethernet, OTN (Optical Transport Network), and SONET/SDH protocols.
