Systems and methods for preventing service interruption when troubleshooting a passive optical network

A method performed by a passive optical network (PON) testing device, the method comprising:

• receiving a plurality of fiber optic cables in a plurality of slots of the PON testing device,
• wherein each fiber optic cable, of the plurality of fiber optic cables, is received in a respective slot of the plurality of slots,
• wherein the PON testing device includes a plurality of light sources, and
• wherein each light source, of the plurality of light sources, is associated with a respective slot of the plurality of slots;
• causing, by a plurality of protruding members of the PON testing device, the plurality of fiber optic cables to bend, in the plurality of slots, to emit light;
• filtering, by a light detection unit of the PON testing device, the light emitted by the plurality of fiber optic cables;
• determining, by the light detection unit, whether light emitted by a fiber optic cable, of the plurality of fiber optic cables, is detected after filtering the light emitted by the plurality of fiber optic cables;
• and
• providing, by the light detection unit, an indication regarding the fiber optic cable based on determining that the light emitted by the fiber optic cable is detected.

A system comprising:

• a testing light source configured to emit test light and to be connected to one of a plurality of fiber optic cables,
• wherein each fiber optic cable, of the plurality of fiber optic cables, is connected to a respective port of a plurality of ports of a passive power splitter;
• and
• a passive optical network (PON) testing device comprising:
• a first portion comprising a plurality of slots configured to receive the plurality of fiber optic cables,
• wherein each fiber optic cable, of the plurality of fiber optic cables, is received in a respective slot of the plurality of slots;
• a second portion comprising a plurality of protruding members configured to bend the plurality of fiber optic cables, received in the first portion, to cause the plurality of fiber optic cables to emit light;
• and
• a light detection unit comprising a plurality of light sources,
• wherein each light source, of the plurality of light sources, is associated with a respective slot of the plurality of slots, and
• wherein the light detection unit is configured to:
• determine whether the light, emitted by a particular fiber optic cable of the plurality of fiber optic cables, is the test light, and
• provide an indication regarding a particular port of the plurality of ports based on determining that the light, emitted by the particular fiber optic cable, is the test light,
• wherein the particular fiber optic cable is connected to the particular port.
