R-2521Z  光纤接收器 具有高性能链路接收器

R-2521Z是AVAGO公司生产的光纤收发器。

R-2521Z是全新原装，具有高性能链路接收器，接收器具有5MBd。

R-2521Z是光纤收发器的一种，用于光信号转换。

光纤收发器是一种将短距离的双绞线电信号和长距离的光信号进行互换的以太网传输媒体转换单元，在很多地方也被称之为光电转换器。一般应用在以太网电缆无法覆盖、必须使用光纤来延长传输距离的实际网络环境中，且通常定位于宽带城域网的接入层应用，如：监控安全工程的高清视频图像传输；同时在帮助把光纤最后一公里线路连接到城域网和更外层的网络上也发挥了巨大的作用。

The R-2521Z is a fiber optic transceiver manufactured by AVAGO Corporation.

The R-2521Z is new and original with a high performance link receiver with a 5MBd receiver.

The R-2521Z is a type of fiber optic transceiver used for optical signal conversion.

Optical fiber transceiver is a kind of Ethernet transmission media conversion unit that exchanges short-distance twisted pair electrical signal and long-distance optical signal, and is also called photoelectric converter in many places. It is generally used in the actual network environment where Ethernet cables cannot be covered and optical fibers must be used to extend the transmission distance, and is usually located in the access layer applications of broadband metropolitan area networks, such as: high-definition video image transmission for monitoring security engineering; It has also played a huge role in helping to connect the last mile of fiber to the metropolitan area network and beyond.

A photoelectric converter is a device that converts an optical signal into an electrical signal, or an electrical signal into an optical signal.

R-2521Z photoelectric converter, also known as optical fiber transceiver, is a device similar to baseband MODEM (digital modem), which is an Ethernet transmission media conversion unit that exchanges short-distance twisted pair electrical signals and long-distance optical signals. It is also known as a Fiber Converter in many places. R-2521Z products are generally used in the actual network environment where Ethernet cables cannot be covered and optical fibers must be used to extend the transmission distance, and are usually located in the access layer applications of broadband metropolitan area networks. For example: monitor the transmission of high-definition video images for security projects; It has also played a huge role in helping to connect the last mile of fiber to the metropolitan area network and beyond.
