Abstract
A bi-directional amplifier system comprises a 2×2 interleaved channel separator optically coupled to both a first and a second bi-directional fiber optic communications line and an optical amplifier optically coupled to the 2×2 interleaved channel separator. A method of bi-directional optical amplification comprises the steps of: (a) inputting a first plurality of optical channels from a first optical communications line to and a second plurality of optical channels from a second optical communications line to first port and a second port, respectively, of a 2×2 interleaved channel separator; (b) outputting the first plurality and the second plurality of optical channels from a third port of the interleaved channel separator to the input of an optical amplifier; (c) outputting the first plurality and the second plurality of optical channels from the output of the optical amplifier to a fourth port of the interleaved channel separator; and (d) outputting the first plurality of optical channels to the second fiber optic communications line and the second plurality of optical channels to the first fiber optic communication s line from the interleaved channel separato…
