ocr: HOMDHTATRANSMISSION FLOW Data Receivers sources Wavelength Optical ampiflers multiplexer Demultiplexer Fiber transmlssion line Lasors (at various wavciengths) Figure 1. The WDM dara flow process is relatively straighnsforward. Multiple wavelengths of light E consolidated and traverse a. single fiber optic line. Amplifiers maintain the continuity of the signals, which are erentually split and sent to their fual destinations.
