A fiber-optic patch cord is a fiber-optic cable capped at each end with connectors that allow it to be rapidly and conveniently connected to telecommunication equipment. This is known as interconnect-style cabling.
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.
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.
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 ...
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.
RG-58/U is a type of coaxial cable often used for low-power signal and RF connections. The cable has a characteristic impedance of either 50 or 52 Ω. "RG" was originally a unit indicator for bulk RF cable in the U.S. military's Joint Electronics Type Designation System.
This is a list of universities in Nigeria. Nigeria is organised into 36 states and the Federal Capital Territory. As a result of the oil boom years of the 1970s, tertiary level of education was expanded to reach every sub-region of Nigeria. [1] [2] The federal and state governments were previously the only bodies licensed to operate ...
For example, the common "patch cables" used for Ethernet (and the similar cords used for telephones) typically have male modular plugs on both ends, to connect to jacks on equipment or mounted in walls. Common 5.5×2.5 mm coaxial power connectors.
