1. A method for providing an optical network configured for bi-directional communication using optical signals, the method comprising:
- selecting a first operator comprising a first optical transmitter and a second optical receiver optically coupled to a first asymmetric optical combiner/splitter, the first asymmetric optical combiner/splitter coupling the first operator to a first end of optical media;
selecting a second operator comprising a second optical transmitter and a second first optical receiver optically coupled to a second asymmetric optical combiner/splitter, the second asymmetric optical combiner/splitter remotely coupled to the optical media;
attenuating a first signal transmitted from the first optical transmitter based on a low transmittance ratio, TR, corresponding to the first asymmetric optical combiner/splitter prior to providing the first signal to the optical media;
attenuating the first signal received from the optical media based on a high transmittance ratio, TR, corresponding to the second asymmetric optical combiner/splitter prior to providing the first signal to the first optical receiver;
attenuating a second signal transmitted from the second optical transmitter based on a low transmittance ratio, TR, corresponding to the second asymmetric optical combiner/splitter prior to providing the second signal to the optical media; and
attenuating the second signal received from the optical media based on a high transmittance ratio, TR, corresponding to the first asymmetric optical combiner/splitter prior to providing the second signal to the second optical receiver; and
selecting the second optical transmitter for operation at substantially a same wavelength as the first optical transmitter.
