A bi-directional optical communication system. A first optical fiber includes a plurality of pieces, each piece having a first and second end. An optical amplifier for amplifying optical signals transmitted in a first direction is coupled to first and second pieces of the first optical fiber. A second optical fiber is coupled to the first and second pieces, bypasses the optical amplifier and transmits optical signals in a second direction opposite to the first direction. A first optical signal generator apparatus coupled to the first piece of the first optical fiber provides optical signals propagating in the first direction to a optical receiver apparatus coupled to the second piece of the first optical fiber. A second optical signal generator in the optical receiver apparatus provides optical signals propagating in the second direction to the first optical signal generator apparatus. A second optical receiver and a monitor, both in the first optical signal generator apparatus, receive the optical signals propagating in the second direction and monitor various operating conditions of the optical communication system.
