Patent ID: 8417114

Claim:
An optical test device comprising: at least one optical filter coupled with a first optical fiber, the at least one optical filter configured to allow an optical signal on the first optical fiber to pass from the first optical fiber to a second optical fiber; at least one monitoring device coupled with the at least one optical filter, the at least one monitoring device configured to receive a portion of the optical signal to test the optical signal; and a first switch in communication with the first optical fiber, the first switch configured to switch the optical signal on the first optical fiber to a third optical fiber for loop-back testing; and the optical test device includes an optical device to provide the signal to the optical test device; wherein the optical device is a provider test device comprising: at least one optical switch coupled to the first optical fiber to transmit the signal to the optical test device; a test laser coupled to the at least one optical switch to provide the signal to the at least one optical switch; and a control interface communicatively connected to the test laser to initiate when the signal is provided to the at least one optical switch.
