Regarding the connection of the cable mentioned above, levels of the signals A and B are
–48 VDC and ground, respectively, hence, order of the wires matters while the connection is
being made.
A TWT line can be extended to distances up to 2 km. with 0.5 mm. copper cable. That
distance can be extended even further by using thicker cables. However, it is extremely
important that there is no splice on the cable and it is supposed to be isolated from
environmental effects.
