Abstract
An apparatus and method for monitoring an optical fiber that links a first node and a second node. An apparatus includes: a first transmitting part for outputting a first check light, which is modulated by the first pattern signal, to the optical fiber link. A first receiving part demodulates the second pattern signal from the second check light, which is input by the optical fiber link. A first processor generates the first pattern signal and outputs the first pattern signal to the first transmitting part, and receives the second pattern signal from the first receiving part.

An apparatus for monitoring an optical fiber link linking a first node and a second node, comprising:
- a first optical fiber monitoring apparatus including:
- a first transmitting part for outputting a first check light, which is modulated by a first pattern signal, to the optical fiber link;
- a first receiving part for receiving and demodulating a second pattern signal from a second check light, which is input via the optical fiber link;
- and
- a first processor for generating the first pattern signal and outputting the first pattern signal to the first transmitting part, and for receiving the second pattern signal from the first receiving part.
A method for monitoring an optical fiber link linking a first node and a second node, the method comprising:
- outputting a first check light by a first transmitting part, which is modulated by a first pattern signal, to a optical fiber link;
- receiving and demodulating a second pattern signal from a second check light received from the optical fiber link by a first receiving part;
- and
- generating the first pattern signal by a first processor and outputting the first pattern signal to the first transmitting part, and the first processor receiving the second pattern signal from the first receiving part.
