B.The average optical power of the optical interface is measured as follows. One end of the pigtail is connected to the light receiving interface of the optical board and the other end is connected to the input interface of the optical power meter. After the optical power becomes stable, read the value, which is the transmitting optical power of the optical interface.
C.The sensitivity and overload indicator of optical interface are measured as follows. Increase the adjustable optical attenuator gradually and observe the critical value when the optical interface generates an error code. Record the optical power value at this time, which is the sensitivity.
D.The sensitivity and overload indicator of optical interface are measured as follows. Reduce the adjustable optical attenuator gradually and observe the critical value when the optical interface generates an error code. Record the optical power value at this time, which is the overload indicator.
