Description
Optical patch cords are used to switch optical communication lines and connect them to network and measuring equipment. An optical patch cord is a fiber optic cable terminated with an optical connector, if the cable is terminated only on one side, this kind of patch cord is called a pigtail. For our patch cords and pigtails we use only the best Corning fiber, an important factor in the quality of the patch cord is also the quality of the connector and in our connectors we use only ferrules (Ferrule Connector) of Adamant japanese company.
The optical connecting cord is a patch cord terminated on different sides by means of different types of connectors. Just as the pigtail, a is single-mode and multi-mode are provided.
