FTTH Testing

A testing method, based on simultaneous upstream/downstream measurement techniques, that is applied to a network whose fiber is deployed from the central-office telephone switch all the way to a subscriber's premises or home. From installation to activation to troubleshooting, the basic test sets include optical loss testing, optical line mapping, optical time-domain reflectometry, as well as power meters and inspection probes.
