Abstract
A method of transmitting bidirectional telephony communication signals on a single optical fiber. The bidirectional signals are transmitted in one direction as NRZ coded signals at a first clocking pulse rate, and in the other direction as modified a hybrid form of ON-OFF keying coded signals having pulse transitions at a second clocking pulse rate which is a multiple (preferably eight times (8×)) of the first clocking pulse rate, wherein the modified Manchester coded signal is modified by ON-OFF keying.
