Patent ID: 7414386

Claim:
A method of testing an optical component, comprising: receiving an optical signal from an optical component, the optical signal including AC and DC components; converting the optical signal to an electrical signal; separating AC and DC components of the electrical signal, wherein separating the AC and DC components of the electrical signal comprises: using a first matching network of the test apparatus, receiving a high output of a differential output of an amplifier associated with the optical receiver of the test apparatus; using a second matching network of the test apparatus, receiving a low output of the differential output of the amplifier; and using a first filter associated with the first matching network and a second filter associated with the second matching network to separate the AC component and the DC component; converting the AC component of the electrical signal to a function of the RMS value of the AC component of the electrical signal; and providing the function of the RMS value to a data acquisition system.
