Claim:
1. An optical system comprising: an optical test device including a first optical filter coupled with a first optical fiber, the first optical fiber carrying a test signal on at least one wavelength carried by the first optical fiber, the first optical filter configured to allow the test signal to pass from the first optical fiber to a second optical filter of the optical test device, the second optical filter configured to place the test signal on a second optical fiber, and wherein the optical test device further comprises a monitor configured to receive the test signal from the first optical filter, the monitor configured to determine at least one characteristic of the first optical fiber; and a network device coupled with the second optical fiber, the network device including a third filter configured to receive the test signal if it is present on the second optical fiber and wherein the monitor is configured to transmit at least one data packet to the network device on the at least one wavelength used for the test signal, the data packet representing the at least one characteristic of the first optical fiber.
