(Wavelength division multiplexing system 2U 1U equipment is a miniaturized, low-cost, high-speed, large-capacity wavelength division multiplexing transmission system launched by Lightway Technology; the number of channels can reach 40 waves, and the maximum rate of a single channel is 10Gbit/s , with a total capacity of 400Gbit, which can meet the needs of telecom operators for ultra-large capacity and ultra-long interval transmission to the greatest extent, and is currently the best solution to deal with serious optical cable resources. WDM wavelength division multiplexer EDFA fiber amplifier DCM dispersion compensator makes it not a dream for a comprehensive wavelength division multiplexing system to transmit hundreds of G and hundreds of thousands of kilometers.)
