Even though CFP and CXP have similar abbreviations and appear almost simultaneously, their form factor is different in size, density and target applications. CFP and CXP form factors are both hot-swappable, support for sending and receiving functions, and support for data rates of 40Gbps and 100Gbps. CFP is mainly targeted at 40G and 100G Ethernet applications, supports single-mode or multimode fiber, and can adapt to a series of data rates, protocols and link lengths. On the contrary, CXP is mainly targeted at the cluster and high-speed computing markets. Therefore, judging from these aspects, CFP and CXP complement each other, not competing. In this article, Gigalight (gigalight.com) will take a look at these two optical transceiver transceivers, and to help you better distinguish them.
What Is CFP Optical Transceiver?
Designed primarily for the 100G market, the CFP optical transceiver is specifically sized for long range interfaces and single-mode fiber applications. It is 120mm long and 86mm wide. It is the same length as a 10G XENPAK optical transceiver but twice as wide. At the same time this optical transceiver has good thermal performance, making it in the process of using small power consumption.
Gigalight can provide several kinds of mainstream CFP optical transceivers: CFP 100GBASE-SR10, CFP 100GBASE-LR4, CFP2 100GBASE-SR10, CFP2 100GBASE-LR4, and 100GBASE-SR4 CFP4. Beised, it will release the latest 100G CFP2 ER4/100G CFP ER4 in January, 2018. These optical transceivers can achieve different transmission distances by connecting with different types of optical fibers.
|CFP 100GBASE-LR4||Dual LC||10KM|
|CFP2 100GBASE-LR4||Dual LC||10KM|
What Is CXP Optical Transceiver?
CXP optical transceiver is 45 mm long and 27 mm wide and optically larger in size than the XFP optical transceiver. Built-in 12 transmission channels, each channel to 10Gb / s speed, the maximum rate of up to 120G, mainly used to meet the high density of data centers, usually with multi-mode fiber optic ribbon used in parallel, the transmission distance up to 100 meters. The following table will take CXP 100GBASE-SR10 as an example to understand the parameters of this optical transceiver.
|Transmission Distance||400m||Maximum Link Length||300m on OM3 or 400m on OM4|
What Is the Relationship between CFP and CXP?
There are many similarities and differences between CFP optical transceivers and CXP optical transceivers, and in some cases, there is competition between CFP optical transceivers and CXP optical transceivers because CFP can also be used with multimode optical fibers. The specific depends on the user’s choice, if you need to build a network that can adapt to a variety of speeds then use the CFP optical transceiver; if it is mainly used for short-distance transmission, then may need more CXP optical transceiver. CFP and CXP form factors are complementary, CFP is mainly used in Ethernet switches, core routers and optical transmission equipment, and CXP is used in the Data Center market.
No matter which optical transceiver you need, Gigalight can meet your needs. There are also other optical communication products like 100G optical transceivers that can help you solve optical network issues.
