Abstract
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 l…
