The Navy issued a final drawing RE 49F 246, dated December 2, 1944. [1] In May 1945, Octavio M. Salati of Hazeltine Corporation applied for a patent for the BNC, which was granted in January 1951. [2] In 1958, Hazeltine sued Dage Electric Company, a maker of BNC connectors, for infringement on this patent.
The DIN 1.0/2.3 connector is a RF connector used for coaxial cable at microwave frequencies. They were introduced in the 1990s [ 1 ] for telecommunication applications. They are available in 50 Ω and 75 Ω impedance and are compatible with the most widely used cable sizes.
Because the patch cord is stranded copper construction the attenuation (signal loss) is higher on patch cords than solid cable so short lengths should be adhered to. [ 1 ] They can be as short as 3 inches (76 mm), to connect stacked components or route signals through a patch panel , or between 6 and 50 metres (20 and 164 ft) for snake cables.
The maximum practical number of nodes that can be connected to a 10BASE2 segment is limited to 30 [4] with a minimum distance of 0.5 metres (20 in) between devices. [5] In a 10BASE2 network, each stretch of cable is connected to the transceiver (which is usually built into the network adaptor) using a BNC T-connector , [ a ] with one stretch ...
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.
Flat no-leads packages such as quad-flat no-leads (QFN) and dual-flat no-leads (DFN) physically and electrically connect integrated circuits to printed circuit boards. Flat no-leads, also known as micro leadframe (MLF) and SON (small-outline no leads), is a surface-mount technology , one of several package technologies that connect ICs to the ...
