摘要： A method of monitoring fiber optic circuits. Included is manipulating a first switch between a first state, with first connection points optically linked along a first optical signal pathway and second connection points optically linked along a second optical signal pathway, and a second loopback state, with the first and second connection points of a first pair of connection locations in communication along a path along a portion of the first and second optical signal pathways. With the first switch in the first state, a third pair of connection locations are linked to the first optical pathway and the optical throughout observed. The third pair of connection locations are then linked to the second optical pathway and the optical throughout observed. These steps are repeated as long as the first and second optical pathways transmit the optical throughout normally.

摘要： A fiber optic circuit provides signal access and monitoring. A module housing the circuit and the module is mountable to a chassis. The module housing includes mounting flanges for mounting the module to the chassis; and a plurality of exposed adapters along at least one of the front and rear faces. Each of the plurality of adapters is connectable to a fiber optic connector external to the module. The plurality of adapters define first and second transmit signal ports and first and second receive signal ports. A transmit signal pathway is between the first and second transmit signal port. A receive signal pathway is between the first and second receive signal ports. A first switch, such as a 2×2 switch, is between the transmit and receive signal pathways wherein the switch has first and second states, the first state being a normal through state wherein the first and second transmit signal ports are in communication along the transmit signal pathway, and wherein the first and second receive signal ports are in communications along the receive signal pathway, and a loopback state wherein the first transmit signal and the receive signal port are in communication along a first loopback path along a portion of the transmit and receive signal pathways, and wherein the second transmit and receive signal ports are in communication along a loopback path along other portions of the transmit and receive signal pathways. A second 2×2 switch or a 1×2 switch allows access for testing with test equipment and a 1×N optical switch. The various switches can be remotely controlled.

摘要： An apparatus for non-blocking event reporting from event reporting units to a monitoring circuit includes a first and second common wire coupling the units to the monitoring circuit. A constant level signal is generated on the first wire and a pulse signal is generated on the second wire. The monitoring circuit detects the level and pulse signals and reports multiple overlapping events occuring at the event reporting units.
