Which of the following description about the relationship for FEC delay is correct? (Multiple choice)
A . Typical AFEC time delay of 40G coherent signals is greater than Typical FEC delay
B . 100G SDFEC delay (20%) is greater than 100G HFEC delay (7%)
C . 100G HFEC latency is greater than 40G AFEC latency
D . The transmitting end adds overhead to encode, and the receiving end performs decoding to cause signal delay.
