Abstract:
1. A wavelength division multiplexing system, comprising: a client receiver for receiving a first optical signal; a first optical/electric converter for converting the first optical signal to a first electrical signal; a line transmitter, tuned to a first wavelength by a tunable laser, for transmitting a second optical signal converted from the first electrical signal at the first wavelength; a line receiver for receiving a multiplexed incoming optical signal, the line receiver tuned by a tunable filter to select a signal at a second wavelength within the multiplexed incoming optical signal; a second optical/electrical converter for converting the multiplexed incoming optical signal to a second electrical signal; a client transmitter for transmitting a third optical signal converted from the second electrical signal; and a display device for displaying in real time an identification of the first wavelength in a first selectable mode and an identification of the second wavelength in a second selectable mode.
