In optical fiber communication, when optical fiber transmits optical signal, the optical signal will attenuate along the optical fiber transmission path, and the transmission distance is limited by optical fiber attenuation. In order to transmit the signal further, we need to enhance the optical signal. The traditional method of enhancing the optical signal is to use the regenerator, but it has ma...

CPRI is the abbreviation of Common Public Radio Interface, a standardized communication protocol widely adopted in mobile communication base stations. CPRI plays the role of transmitting baseband I / Q signals to radio units in traditional BS (base station). CPRI has efficient and flexible I / Q data interfaces for various standards, such as GSM, WCDMA, LTE, etc. Unlike the data center, the CPRI o...
