Introduction to 100G Transceiver CFP
100G Ethernet is expected by more and more internet users in order to satisfying their increasing need for higher internet speed and greater bandwidth. Under this circumstance, 100G Ethernet sprang up like the mushrooms in recent years. It is the rising star in the telecommunication industry, so we need to understand 100G Ethernet and its applications in the following content.
100G Ethernet refers to computer networking technologies for transmitting Ethernet frames at rates of 100 gigabits per second (100Gbit/s), respectively. This technology was first defined by the IEEE 802.3ba-2010 standard. It usually needs a variety of devices to build and support the 100G Ethernet. The 100G transceiver is one of the essential one, because fiber connectivity is being condensed and simplified with plug-and-play, hot-swap transceiver miniaturization in higher-speed active equipment.
100G transceiver provides customers 100 Gigabit Ethernet connectivity options for data center networking, enterprise core aggregation, and service provider transport applications. 100G transceivers offer significant advantages over existing solutions in terms of reduced power dissipation and increased density with the added benefit of pluggability for reduced first installed cost. CFP is the common type of 100G transceivers
The CFP transceiver is defined as hot-pluggable optical transceiver form factors to enable 40 Gbit/s and 100 Gbit/s applications, which is specified by a multi-source agreement to produce a common form-factor for the transmission of high-speed digital signals. The c stands for the Latin letter C used to express the number 100 (centum). CFP transceiver was designed after SFP transceiver interface, but it supports much larger internet speed — 100G, which is realized by using 10×10Gbit/s in each direction. The 100G optical interconnects typically means 100GBASE-SR10 in 100 meter MMF, 100GBASE-LR10 and 100GBASE-LR4 in 10km SMF reach, and 100GBASE-ER10 and 100GBASE-ER4 in 40km SMF reach respectively.
CFP transceiver is currently defined two next generation 100G form factors — CFP2 and CFP4. Compared to the existing CFP, CFP2 and CFP4 will be respectively double and quadruple front panel port density. A brief introduction will be given to CFP2 and CFP4.
CFP2 optical transceiver is the half size of a CFP, but it enables users to double their front panel density. The typical size of a CFP2 optical transceiver is 41.5mm nominal width with 104 pin electrical connection. And there is no digital signal processor in package, relying on host card. On the other hand, CFP2’s power usage is less than 12w and it supports 10×10G or 4×25G or 8×25G lanes. CFP2 optical transceiver is available in 100GBASE-LR4 CFP2, 100GBASE-CR10 CFP2, 100GBASE-CR4 CFP2, etc. However, CFP4 transceiver is much smaller than CFP2, which provides 56 pin electrical connection. Its power usage is less than 6w and it also supports 10×10G or 4x25G lanes. In all, CFP2 and CFP4, compared with CFP, are not widely popular in the market due to the high cost of development and research.
CFP transceiver is widely available in the market, especially with the development of 100G Ethernet in recent years. Fiberstore, the leading manufacturer and supplier of optical communication products, strives to offering the best solution for all the customers. We provide many types of CFP2 optical transceivers with high quality and a competitive price, such as 100GBASE-LR4 CFP2, 100GBASE-CR10 CFP2, 100GBASE-CR4 CFP2.
