1. A system comprising:
a reflectometer and optical fiber connection device comprising:
a Rayleigh wavelength pass filter to pass, in one direction, a Rayleigh signal of an optical reflectometer signal to an optical fiber; and
a Raman wavelength pass filter to:
filter out, in another direction, Rayleigh backscattering from the optical reflectometer signal; and
pass, in the another direction, a Raman Anti-Stokes signal from the optical fiber,
wherein the Raman wavelength pass filter is different from the Rayleigh wavelength pass filter.
