LVDS Cables – LVDS (low voltage differential signal) cables are frequently used as an economic method of connecting TFT displays to their driver boards. Using low power, the LVDS cables utilise twisted pairs to send out the signal from the PCB to the display over distances of up to 10 metres.
The connectors are generally fine pitch, usually under 1 mm, and for that reason accept small gauge wires. This results in a really low-profile and versatile cable assembly, enabling routing through the tightest of units.
eDP Cables – eDP (embedded DisplayPort) cables are beginning to supersede LVDS since the cable assembly preferred by connecting driver boards to TFT displays. They use the identical digital signal processing protocol as DisplayPort cables, but in a smaller physical connector.
Often manufactured from micro-coax cable, eDP cable assemblies require fewer connections than LVDS. Additionally they offer all power, data and control signals through one assembly. Where LVDS assemblies could require 18 signal wires, eDP Cable would only use five.
The coaxial cable was invented in 1929. However, its commercial use started only in 1941. Coaxial cables include round, cylindrical shaped wires that is included in a spacer, a cylinder shaped sheath which in turn is in the middle of an insulating jacket. Coaxial cable is actually a power cable and is also employed to transfer high frequency signals. The electromagnetic field generated is found between the inner as well as the outer conductors. There is therefore less interference from outer electromagnetic fields. This kind of cabling is used for industries like cable TV and networking. Coaxial cabling is a little more expensive than usual telephone cabling. However, it is preferred as it allows maximum transmission of data and data with all the least interference.
These cables are normally of 2 types- flexible and rigid. Rigid cables contain solid form of sheath and versatile cable consists of braided type sheath of copper. The inner insulator (or dielectric) affects the cable’s properties, such as attenuation and impedance. RF connectors are used to connect the ends of coaxial cables. Dielectric might be solid or perforated with small holes.
The RF connector is actually a short as well as a rigid type of cable having the same impedance as those of cable in which it is actually associated. However, the dielectric may not be same. The connectors with higher quality are normally coated with gold, but lower quality cables are coated with nickel. Silver can also be used (only in the event of high-end connectors) as its conductivity is actually good. Silver plating normally requires additional coating due to its oxidation in air.
A full list of the many type of coaxial cable can be found at category5-cable.com/plenum-cat-5.html, and are summarized below: Hard Line – They are the powerful cables with rigid outer shield with minimum loss. Normally employed to connect a transmitter plus an antenna. These cables consists of high dielectric in high temperature also.
Tri axial – Cable with three layers of shielding and also the outermost shielding protecting the inner layers from from outer electromagnetic interference. Twin axial – This cable is made up of twisted pair covered tmcaao a shield. Bi axial – Contains two 50O coaxial cables used for networking. Semi rigid – This is a coaxial cable with solid outer copper sheath.
Short type of coaxial cables are simply utilized for home video, ham radio and some small computer networks while long coaxial cables connect radio or television networks. Micro coaxial cables are employed through the military or medical use. Micro coaxial cables are used in a selection of consumer devices, military equipment and in addition in ultra-sound scanning equipment. The cables with impedances of 50/52 and 75 ohms are normally used. 50/52 ohm cables are typically used for commercial purposes while 75 ohm cables can be used for domestic purpose.
