Paper Abstract

We investigated the first- and second-order round-trip local birefringence vectors (which are the round-trip local birefringence vector and its derivative, respectively) obtained by using P-OTDR technique in optical fibers. We found the twist-induced circular birefringence can be expressed with the modulus of the two vectors and the derivative of the modulus of the first-order vector. Based on this theory, twist-induced circular birefringence distribution along the fiber can be measured. We also proposed a simple way to measure the round-trip local birefringence vectors
