Type E uses Bi-Phase Modulation [Manchester II phase encoding]. The impedance is 50 ohms + 5 ohms, a 50 ohm Triaxial cable is defined [center conductor is the signal, the other two are shields]. MIL-C-17/134 cable is used for lengths up to 120 meters, MIL-C-17/135 is used for cable lengths up to 300 meters.
This will increase with the length of the cable. DC resistance usually has less effect on a signal than insertion loss, but plays a major role if power over Ethernet is required. Also measured in ohms is the characteristic impedance of the cable, which is independent of the cable length.
The cable is wholly owned by Lumen (formerly Level 3 Communications) in the US following its acquisition of Global Crossing. [1] The original owners, which each owned two of the fibre pairs, gave this cable system different names, so it is known as both Yellow (after the Beatles song Yellow Submarine) and AC-2. It has a capacity of 320 Gbit/s ...
MIL-STD-1553B does not specify the length of the cable. However, the maximum length of cable is directly related to the gauge of the cable conductor and time delay of the transmitted signal. A smaller conductor attenuates the signal more than a larger conductor. Typical propagation delay for a 1553B cable is 1.6 nanoseconds per foot.
Digital Signal 3 (DS3 or T3 line) is a digital signal level 3 T-carrier.The data rate for this type of signal is 44.736 Mbit/s (45 Mb). It can transport 28 DS1 level signals within its payload.
Data rate versus line length chart, from RS-422 Annex A.1. Several key advantages offered by this standard include the differential receiver, a differential driver and data rates as high as 10 megabits per second at 12 meters (40 ft). Since the signal quality degrades with cable length, the maximum data rate decreases as cable length increases.
A cable terminated according to T568A on one end and T568B on the other is a crossover cable when used with the earlier twisted-pair Ethernet standards that use only two of the pairs because the pairs used happen to be pairs 2 and 3, the same pairs on which T568A and T568B differ. Crossover cables are occasionally needed for 10BASE-T and ...
Designed to support short distances over copper cabling, it uses InfiniBand 4x connectors and CX4 twinaxial cabling and allows a cable length of up to 15 m. Was specified in IEEE 802.3ak-2004 which has been incorporated into IEEE 802.3-2008.
