One, refer to different

1. Ribbon optical cable: Multi-core optical fibers (4, 6, 8, 12 cores, etc.) are glued together with special materials to form a group (also called a belt), and multiple groups (belts) form an optical cable.

2. Optical cable: It is manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups Components.

Two, the characteristics are different

1. Ribbon optical cable: optical cable with hundreds of cores, small diameter, light weight, good bendability and strong ability to resist lateral pressure, and it is convenient to lay and construct. Multi-core is one area, can be connected at one time, fast, less time-consuming, and high construction efficiency. It is easy to reel fiber and the sequence is not easy to make mistakes. The maintenance of ribbon optical cable and the emergency repair of obstacles are also more convenient.

2. Optical cable: The traction end of the optical cable can be prefabricated or made on site. Directly buried or underwater armored optical cable can be used as a net sleeve or traction end. In order to prevent twisting and damage to the optical cable during the towing process, a swivel should be added between the towing end and the towing rope. When laying out the optical cable, the optical cable must be released from the top of the cable reel and maintain a slack arc. There should be no twisting during the laying process of the optical cable, and it is strictly forbidden to make small loops and surges.

Three, different uses

1. Ribbon optical cable: It has high optical fiber integration and good comprehensive mechanical properties, especially the resistance to lateral pressure and bending. It is widely used in metropolitan area networks and access networks, and is used in central bundle tube ribbon design. , The design and selection of its cable core structure and strengthening unit are very important.

2. Optical cable: When the number of cores is the same, the outer diameter of the skeleton type optical fiber ribbon cable is the smallest, and the unidirectional skeleton type optical fiber cable is particularly obvious. With the rapid development of the metropolitan area network and the access network, the skeleton type ribbon fiber Wide range of applications.
