Connecting block | A basic part of any telecommunications distribution system. Also called a terminal block, a punch-down block, a quick-connect block, and a cross-connect block, a connecting block is a plastic block containing metal wiring terminals to establish connections from one group of wires to another. Usually each wire can be connected to several other wires in a bus or common arrangement. There are several types of connecting blocks, such as 66 clip, BIX, Krone, or 110. A connecting block has insulation displacement connections (IDCs), which means you don

Connector | With respect to cabling, a device attached to the end of a cable, receiver, or light source that joins it with another cable, device or fiber. A connector is a mechanical device used to align and join two conductors or fibers together to provide a means for attaching and decoupling it to a transmitter, receiver, or another fiber. Commonly used connectors include the RJ-11, RJ-45, BNC, FC, ST, LC, MT-RJ, FDDI, Biconic, and SMA connectors.
