Power line carrier relay protection
Carrier Blocking Protection Scheme – The carrier blocking protection scheme restricts the operation of the relay. In 1919, the first system for voice-communication purposes was placed into service. And then the phase angle of the line decides. Protective Relaying schemes use pilot channels to transmit local information to the remote end in order to make the proper decision to trip or not to trip for a fault on the line. Powerlines provide a reliable link because of their unusually rugged construction, and also offer freedom from restrictions imposed by common-carrier regulations. PLC. Power-Line Carrier is a communications channel used by the power utilities to provide simple communications on a two-terminal or three-terminal ended transmission line for protective relaying functions. After the direction comparison, the carrier pilot.

Fiber Optics and Carrier Channels
Because the effect of dispersion increases with the length of the fiber, a fiber transmission system is often characterized by its bandwidth–distance product, usually expressed in units of ·km. This value is a product of bandwidth and distance because there is a trade-off between the bandwidth of the signal and the distance over which it can be carried. For example, a common multi-mode fiber with a bandwidth–distance product of 500 MHz·km could carry a 500 MHz signal for 1 km or a 1000 MHz sig.
