110 Block
A 110 block is a type of punch-down block used to terminate runs of on-premises wiring in a structured cabling system. The designation ''110'' is also used to describe a type of insulation displacement contact (IDC) connector used to terminate twisted pair cables, which uses a punch-down tool similar to the type used for the older 66 block. Usage Telephone distribution Early residential telephone systems used simple screw terminals to join cables to sockets in a tree topology. These screw-terminal blocks have been slowly replaced by 110 blocks and connectors. Modern homes usually have phone service entering the house to a single 110 block, whence it is distributed by on-premises wiring to outlet boxes throughout the home in star topology. At the outlet box, cables are attached to ports with insulation-displacement contacts (IDCs), and those ports fit into special faceplates. In commercial settings, this style of ''home run'' or star topology wiring was already in use on 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Category 6 Cable
Category 6 cable (Cat 6) is a standardized twisted pair cable for Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards. Cat 6 must meet more stringent specifications for crosstalk and system noise than Cat 5 and Cat 5e. The cable standard specifies performance of up to 250 MHz, compared to 100 MHz for Cat 5 and Cat 5e. Whereas Category 6 cable has a reduced maximum length of when used for 10GBASE-T, Category 6A cable is specified for 500 MHz and has improved alien crosstalk characteristics, allowing 10GBASE-T to be run for the same maximum distance as previous Ethernet over twisted pair variants. History Cat 6, an unshielded twisted-pair (UTP) design, emerged as an advancement of the UTP Cat 5e and was formalised in 2001. The design of Cat 6 required more stringent precision in manufacturing, which enabled reduced noise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telephony Equipment
Telephony ( ) is the field of technology involving the development, application, and deployment of telecommunications services for the purpose of electronic transmission of voice, fax, or data, between distant parties. The history of telephony is intimately linked to the invention and development of the telephone. Telephony is commonly referred to as the construction or operation of telephones and telephonic systems and as a system of telecommunications in which telephonic equipment is employed in the transmission of speech or other sound between points, with or without the use of wires. The term is also used frequently to refer to computer hardware, software, and computer network systems, that perform functions traditionally performed by telephone equipment. In this context the technology is specifically referred to as Internet telephony, or voice over Internet Protocol (VoIP). Overview The first telephones were connected directly in pairs: each user had a separate telephone wir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrical Wiring
Electrical wiring is an electrical installation of Electrical cable, cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure. Wiring is subject to safety standards for design and installation. Allowable wire and electrical cable, cable types and sizes are specified according to the circuit operating voltage and electric current capability, with further restrictions on the environmental conditions, such as ambient temperature range, moisture levels, and exposure to sunlight and chemicals. Associated circuit protection, control, and distribution devices within a building's wiring system are subject to voltage, current, and functional specifications. Wiring safety codes vary by locality, country, or region. The International Electrotechnical Commission (IEC) is attempting to harmonise wiring standards among member countries, but significant variations in design and installation requirements still exist. Wiring methods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Industries Alliance
The Electronic Industries Alliance (EIA; until 1997 Electronic Industries Association) was an American standards organization, standards and trade organization composed as an alliance of trade associations for electronics manufacturers in the United States. They developed standards to ensure the equipment of different manufacturers was compatible and interchangeable. The EIA ceased operations on February 11, 2011, but the former sectors continue to serve the constituencies of EIA. History In 1924, 50 radio manufacturers in Chicago formed a trade group called the ''Associated Radio Manufacturers''. This organization was designed to control the licensing of the large number of radio patents so that each member could have access to all the relevant patents necessary to build radio transmitters, antennas and receivers. Over time, new electronic technologies brought new members, non-manufacturer members, and name changes. Names in chronological order: * 1924 – ''Associated ...

Spudger
A spudger (also known as a spludger, non-marring nylon black stick tool) is a tool that has a wide flat-head screwdriver-like end that extends as a wedge, used to separate pressure-fit plastic components without causing damage during separation. Uses The flat end of the spudger is often used to loosen or release components inside electronics, for example during the replacement of batteries or touch screens for smartphones. The other end is often a point or a hook depending on application. When applied to separate pressure-fit panels, there is often a point to create an initial gap before the wedge end is utilized. A spudger is also a wiring tool used for poking or adjusting small wires or components, generally in the electronics and telecommunications industries. A typical spudger is an insulating stick, made of either wood, plastic or a nylon fiberglass material. For instances where the spudger is used for prising it is commonly made of stainless steel or other metals. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keystone Module
A keystone module is a standardized snap-in package for mounting a variety of low-voltage electrical Jack (connector), jacks or optical connectors into a keystone wall plate, face plate, surface-mount box, or a patch panel. Keystone modules have a rectangular face of 14.5 mm wide by 16.0 mm high and are held in place with flexible tabs. This allows them to be snapped into a mounting plate with correspondingly-sized rectangular holes, called ports. Most keystones are interchangeable and replaceable. This provides much flexibility in arranging and mounting many different types of electrical jacks in one plate or panel without requiring customized manufacturing. Some keystones use a pass-through type connector, where there is a jack on both the front face and the rear side. Others only have a jack on the front and employ a different mechanism for hard-wiring signal cables to the rear, such as a mini 110 block, an insulation-displacement connector, or a Crimp (joining), cr ...

Patch Panel
A patch panel is a device or unit featuring a number of jacks, usually of the same or similar type, for the use of connecting and routing circuits for monitoring, interconnecting, and testing circuits in a convenient, flexible manner. Patch panels are commonly used in computer networking, recording studios, and radio and television. The term ''patch'' came from early use in telephony and radio studios, where extra equipment kept on standby could be temporarily substituted for failed devices. This reconnection was done via patch cords and patch panels, like the jack fields of cord-type telephone switchboards. Terminology Patch panels are also referred to as patch bays, patch fields, jack panels or jack fields. Uses and connectors In recording studios, television and radio broadcast studios, and concert sound reinforcement systems, patchbays are widely used to facilitate the connection of different devices, such as microphones, electric or electronic instruments, effects (e ...
