Optical fibers are not affected by interference
... Two types of light source are used with fibers, LEDs and Laser Diodes. LEDs can operate in the near infrared (the main wavelengths used in fibers are 1300nm and 1550nm, along with 850nm for some applications); they can emit light at 850nm and 1300nm. They also have the advantages of long lifetimes ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
