Data Encoding and Modulation. How binary 0 and one are encoded over OC-48, OC-192, OC-256 and OC-768 cables. Which modulation techniques are used by these cables to provide 10 Gbps, 14.271 Gbps and 40 Gbps data transfer rates? Provide the manual ... of encoding, channel capacity, baud rate and modulation techniques used to get 10 Gbps, 14.271 Gbps and 40 Gbps data transfer rates.
