Abstract
An optical transmitter including first, second, third and fourth signal generators configured to transmit first, second, third and fourth optical signals, a first filter configured to combine the first optical signal with the second optical signal to form a first multi-channel signal, a second filter configured to combine the third optical signal with the first multi-channel signal to form a second multi-channel signal, and a third filter configured to combine the fourth optical signal with the second multi-channel signal to form a third multi-channel signal. The first optical signal and the third optical signal have parallel optical axes, as do the second optical signal and the fourth optical signal. The second and fourth optical signals are at an angle of from 5° to 40° with respect to the first and third optical signals and are generally propagated in an opposite direction from the first and third optical signals.
