Abstract
A twisted, multicore fiber communicates light input to each core to an output. The twisting mitigates relative time delays of the input light traveling through each of the cores in the multicore fiber to the output caused by bending of that multicore fiber. An example application is in an optical network that includes an optical input terminal and an optical sensor connected by a twisted multicore connecting fiber. One example of twisted multicore optical fiber is helically-wrapped, multicore fiber.

A method for reducing a variable level of optical skew in an optical network including an optical input terminal and an optical sensor, comprising:
- connecting the optical input terminal and the optical sensor using a twisted multicore fiber,
- compensating for relative time delays of light traveling through each of the cores in the multicore connecting fiber using the twist in the multicore fiber.
A twisted, multicore optical fiber for communicating light input to each core to an output, wherein the twisting of the multicore optical fiber mitigates relative time delays of the input light traveling through each of the cores in the twisted, multicore optical fiber to the output caused by bending of the twisted, multicore optical fiber.
An optical network, comprising:
- an optical input terminal;
- an optical sensor;
- and
- a multi-core connecting fiber connecting the optical input terminal and the optical sensor including means for compensating for relative time delays of light traveling through each of the cores in the multicore connecting fiber caused by one or more bends in the multicore connecting fiber.
