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...

In the establishment of a 10G network, we will face a choice, that is, whether we choose optical fiber cabling or copper cabling. Optical fiber cabling systems are divided into multi-mode（MM) optical fiber cabling systems and single-mode(SM) optical fiber cabling systems, among which 10G MM optical fiber cabling systems need to use 10G SFP+ MM optical modules, 10G AOC active optical...

In high-speed fiber-optic communication, data centers, and long-haul transmission systems, signal integrity is critical. Clock and Data Recovery (CDR) is a core function that ensures stable, error-free transmission for optical modules. Today, ETU-LINK will introduce to you what exactly is CDR clock data recovery: working principle, key roles, industry standards, and typical applications. 1. What i...
