a. The delay time (tc) of conversion between transmitting and receiving is less 

than 1ms.

Timing diagram:

b. 

The delay time of transceivers between the first bit sent by TxD to the first 

bit received by RxD.

As data processing happens on user’s data by KYL-500L transceiver using FEC
(Forward  Error  Correction)  or  other  correction  algorithm, when  RxD  of 
KYL-500L  transceiver ‘A’  receives  the  data,  then  transmits  it,  the  other  one 
transceiver ‘B’ will have a delay (ts) to receive and transmit by TxD. Different 
RF  data  rate  causes  different  delay  time.  Please  see  the specific  delay  time
