A patch cable, patch cord or patch lead is an electrical or fiber-optic cable used to connect ("patch in") one electronic or optical device to another for signal routing. Devices of different types (e.g., a switch connected to a computer, or a switch to a router ) are connected with patch cords.
Rear view of a patch panel with BNC jacks in close proximity. [ 15 ] A BNC inserter/remover tool , also called a BNC tool , BNC extraction tool , BNC wrench , or BNC apple corer , is a tool used to insert or remove BNC connectors in high density or hard-to-reach locations, such as densely wired patch panels in broadcast facilities like central ...
Where BNC is used, available as 3 connectors with Sync on Green, or 5 connector Red / Green / Blue / Horizontal Sync / Vertical sync. Mac-II/Quadra DA15F: 1152 × 870 @ 75 [8] Macintosh: Mac-DA15F and Sun-13W3 were similar in capability to VGA. Some Sun machines used 4 or 5 BNC connectors to transfer video signal. 1990: 13W3 DB13W3: 1152 × 900 ...
For this, fiber patch cables with duplex connectors are normally configured as crossover as is the on-premises wiring. [ citation needed ] Thus, a simple connection with two patch cables at each end and a section of fixed cable in the middle has three crossovers in total, resulting in a working connection.
A fiber-optic patch cord is constructed from a core with a high refractive index, surrounded by a coating with a low refractive index, that is strengthened by aramid yarns and surrounded by a protective jacket. Transparency of the core permits transmission of optic signals with little loss over great distances.
However, the assembly and polishing operations involved can be performed in the field, for example, to terminate long runs at a patch panel. Optical fiber connectors are used in telephone exchanges, for customer premises wiring, and in outside plant applications to connect equipment and fiber-optic cables, or to cross-connect cables.
A punch down tool with interchangeable blades. A punch down tool, punchdown tool, IDC tool, or a Krone tool (named after the Krone LSA-PLUS connector), is a small hand tool used by telecommunication and network technicians.
Zip-cord style jackets, including those that contain Aramid yarn as the strength member, can be slipped over multiple fiber strands coming out of a loose buffer cable to convert it to a complete set of single-fiber cables that can be directly attached to optical connectors. A plastic boot is normally used for strain relief and protection from ...
