Abstract
A passive remote loop-back method and apparatus for optical circuit verification is described. The apparatus may be remotely controlled through either of a dial-up or a data connection. The apparatus is adapted to: perform loop-back of received optical signals; verify status on loss of carrier; and, verify the status of its dual power supplies. The apparatus is also adapted to report alarm conditions by dialing a predetermined telephone number. The advantage is a versatile apparatus that may be monitored by a remote manager, and which automatically reports alarms using a dependable alternate communications medium.
Claims16
Apparatus to enable remote testing of a first fiber optic circuit between a first end point and the apparatus, and a second fiber optic circuit between the apparatus and a second end point, comprising:
- a) a first transceiver for terminating the first fiber optic circuit between the first end point and the apparatus;
- b) a second transceiver for terminating the second fiber optic circuit between the apparatus and the second end point;
- c) a high speed multiplexer interconnecting the first and second transceivers;
- d) a control unit for controlling the high speed multiplexer and monitoring other predetermined functions of the apparatus;
- and
- e) at least one communications port for remotely communicating with the control unit to permit a remote administrator to perform remote testing of the fiber circuit and monitoring of the other predetermined functions of the apparatus.
