Solution Introduction & Advantages

Solution 1: For long distance backbone transmission application scenarios
The four subcarriers based on 100G PM-QPSK modulation are constructed by OFDM technology to implement a 400G superchannel with a channel bandwidth of 150GHz. The scheme has a transmission capacity of 12.8T at C band and the same transmission distance with coherent 100G PM-QPSK Modulation scheme, which can reach 3000km;

Solution 2: For the metro high-speed transmission application scenarios
Two subcarriers based on 200G PM-16QAM modulation are constructed by OFDM technology to form a 400G super channel with a channel bandwidth of 75GHz. The transmission capacity of the scheme is 25.6T and the transmission distance is 500km-600km;

 

Solution 3: For the short-distance metro high-speed transmission application scenarios
Single carrier based on 400G PM-64QAM modulation is constructed by high-order modulation technology to form a 400G super channel with a channel bandwidth of 50GHz. The transmission capacity of the scheme is 38.4T and the transmission distance is 200km, which is quite suitable for  short-distance high-speed transmission scenarios..
