Abstract
A multicore optical fiber assembly is provided. The multicore optical fiber assembly may include an optical fiber, having a fiber diameter, a plurality of active cores, arranged within the optical fiber, and extending along a length of the optical fiber, and an energy blocker disposed within the optical fiber, and extending along the length of the optical fiber. As such, the energy blocker may be disposed between a first active core of the plurality of active cores, and a second active core of the plurality of active cores, where the energy blocker is arranged to block energy transfer from the first active core to the second active core.

A multicore optical fiber assembly, comprising:
- an optical fiber, having a fiber diameter;
- a plurality of active cores, arranged within the optical fiber, and extending along a length of the optical fiber;
- and
- an energy blocker disposed within the optical fiber, and extending along the length of the optical fiber, wherein the energy blocker is disposed between a first active core of the plurality of active cores, and a second active core of the plurality of active cores, and wherein the energy blocker is arranged to block energy transfer from the first active core to the second active core.
A bi-directional optical communications system, comprising:
- a first terminal, to launch a first optical communication traffic in a first direction over a bi-directional optical fiber arrangement;
- a second terminal to launch a second optical communication traffic in a second direction, opposite the first direction, over the bi-directional optical fiber arrangement, wherein the bi-directional optical fiber arrangement comprises:
- a plurality of amplifier assemblies, arranged along a plurality of spans, wherein a given amplifier assembly comprises a fiber amplifier;
- and
- a correcting filter, the correcting filter comprising a gain flattening filter, a shape correcting filter, or a line-build-out element, wherein the correcting filter comprises an optical fiber, the optical fiber being arranged with a plurality of active cores, and an energy blocker arranged to absorb energy from the plurality of active cores.
