Patent ID: 7315668

Claim:
An optical signal distribution point, comprising: an optical testing device operative to provide a test optical signal for testing a network connection between a bidirectional optical coupler and a processor; and the bidirectional optical coupler, comprising: a first port operative to communicate bidirectional optical signals to the processor external to the optical coupler, a second port coupled to the first port, the second port operative to: connect only with the optical testing device, receive the test optical signal from the optical testing device, and transmit the test optical signal to the first port, the test optical signal having a first wavelength, a third port coupled to the first port, the third port operative to: receive a first non-test optical signal having a second wavelength, and transmit the first non-test optical signal to the first port, and a fourth port coupled to the first port, the fourth port operative to: receive a second non-test optical signal having a third wavelength, and transmit the second non-test optical signal to the first port.
