CXP optical module is another high-speed optical module in the 100G optical module market. It is mainly used in the 100G market to meet the high-density needs of data centers. It is usually used with parallel multi-mode optical fiber ribbons with a transmission distance of up to 100 meters. Its size is specifically optimized for long-distance interfaces and single-mode fiber applications, and has good heat dissipation performance, which makes it very small in power consumption during use.
The size of CXP optical module is slightly larger than XFP optical module. It provides 12 parallel data channels. Each channel supports 1.06Gbps to 10.5Gbps, and the maximum rate can reach 120G. It is mainly used to meet data For high-density requirements in the center, it is usually used with parallel multi-mode optical fiber ribbons, with a transmission distance of up to 100 meters, and mainly uses 850nm VCSEL array technology, PIN array and integrated laser driver chip technologies. VCSEL has the characteristics of low threshold current, low power consumption, high modulation rate, easy coupling of circular emission spots and easy manufacturing into an array; while PIN has the characteristics of high sensitivity, fast response rate, low reverse bias and low power consumption.
