Optical cable is a kind of communication line for optical signal transmission by using one or more optical fibers as transmission medium and can be used individually or in groups.

Optical splitter, is one of the most important passive devices in optical fiber links. It is an optical fiber junction device with multiple inputs and multiple outputs.

Data center is a global collaborative network of specific devices used to transfer, accelerate, display, and store data information on the Internet network infrastructure.

Optical passive devices are an important part of optical fiber communication Network, widely used in long-distance communications, regional networks and fiber to the home, video transmission, optical fiber sensing and so on.
