What are the characteristics of the five types of cables
The quality of twisted pair is one of the key factors that determine the LAN bandwidth. Some manufacturers wrap the pairs used in Category 3 or Category 4 UTP cables in Category 5 UTP cables, which is difficult for ordinary users to distinguish

What are the basic cable structure
Optical fiber cable is manufactured to meet the optical, mechanical or environmental performance specifications. It is a communication cable component that uses one or more optical fibers placed in the sheath as the transmission medium and can be used separately or in groups. The optical cable is mainly composed of optical fiber (glass fiber as thin as hair), plastic protective sleeve and plastic sheath. There is no metal such as gold, silver

What are the structures of optical fiber jumpers
Optical fiber jumpers are used to make jumpers from equipment to optical fiber cabling links. It has a thick protective layer, which is generally used for the connection between optical transceiver and terminal box, and is applied in optical fiber communication system

Pay attention to the use of optical fiber jumper
The receiving and transmitting wavelengths of optical modules at both ends of the fiber jumper must be the same, that is to say, both ends of the fiber must be optical modules with the same wavelength. Generally, the short-wave optical module uses multimode optical fiber (orange optical fiber), and the long-wave optical module uses single-mode optical fiber (yellow optical fiber) to ensure the
