The Through-wall Patch cord is a type of cable used to transmit signals through walls or other obstacles, allowing for signal transmission between different rooms or areas. This type of cable is commonly used in applications such as networking, television, telephone, and security systems.
1. Flexibility: Through-wall jumpers allow for flexible placement of equipment and devices as they eliminate the need for direct physical connections between them.
2. Convenience: Through-wall jumpers make it easier to retrofit existing buildings with new equipment or to rearrange equipment in a room without having to run new cables through the walls or ceilings.
3. Versatility: Through-wall jumpers come in different types and configurations to suit various applications, such as coaxial cables, twisted-pair cables, and fiber optic cables.
4. Aesthetics: Through-wall jumpers can help maintain the aesthetic appearance of a room or building by avoiding the need to run visible cables.
Mainly used as wiring cable in user access section of fiber to the home (FTTH) and other optical access (FTTx) network. Can be matched connectors for pre-assembling or field assembling.
