In 1941, the US Navy used a smaller version of the threaded N connector, the Type BN (Baby N), as the UG-85/U, UG-86/U, UG-114/U and UG-115/U. . In 1943, the British introduced a ¼ inch 50 ohm coaxial cable, and companies immediately developed many connectors for it.
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 ...
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. As length increases, the cables are thicker or more shielded, or both, to prevent signal loss ( attenuation ) and the introduction of unwanted radio frequencies and hum ...
A double DIN 1.6/5.6 bulkhead jack connector, crimp type, for 75 Ω coaxial cable A Type N connector (male), right-angled solder-type for semi-rigid coaxial cable with a diameter of 0.141-inch. 4.1-9.5 connector, standardized as DIN 47231 (in 1974) and IEC 60169-11 (in 1977) 4.3-10 connector, formerly known as DIN 4.3/10, now standardized as ...
10BASE2 uses RG-58A/U cable or similar for a maximum segment length of 185 m as opposed to the thicker RG-8-like cable used in 10BASE5 networks with a maximum length of 500 m. The RG-58 type wire used by 10BASE2 was inexpensive, smaller and much more flexible than the specialized RG-8 variant. 10BASE2 can also use RG-59 cable.
A crossover cable may also be used to connect two hubs or two switches on their upstream ports. Because the only difference between the T568A and T568B pin and pair assignments are that pairs 2 and 3 are swapped, a crossover cable may be envisioned as a cable with one modular connector following T568A and the other T568B (see TIA/EIA-568 wiring ...
Sometimes both ends of a cable are terminated with the same gender of connector, as in many Ethernet patch cables. In other applications the two ends are terminated differently, either with male and female of the same connector (as in an extension cord ), or with incompatible connectors, which is sometimes called an adapter cable .
Regardless of copper cable type (Cat 5e/6/6A), the maximum distance is 90 m for the permanent link installation, plus an allowance for a combined 10 m of patch cords at the ends. Cat 5e and Cat 6 can both effectively run power over Ethernet (PoE) applications up to 90 m. However, due to greater power dissipation in Cat 5e cable, performance and ...
