Abstract
Mapping of ports to other network components is generated by physically bending a fiber optic cable and then determining which optical network terminals experience a signal power loss (or receive attenuated signals) based on the bending. The physical bending can be done using a bending tool and the optical network terminals that experience the signal power loss can be identified using a back-end database operation. Generally, the correspondence between the physical bending and the power loss at the downstream components and or upstream components of the network is used to create the mapping of the ports at the splitter level.
Claims18
A method of mapping ports in a passive optical network, the method comprising:
- bending, manually on a fixed groove within a housing of a non-instrument mechanical tool, an optical fiber at a port of a passive component of the passive optical network to cause signal leakage at a bent portion of the optical fiber;
- receiving indications of power losses at downstream and or upstream components caused by the signal leakage;
- and
- mapping at least one downstream component to the port based on the received indications of the power losses.
A system of mapping ports in a passive optical network, the system comprising:
- a non-instrument mechanical tool comprising a housing with a fixed groove that is configured to be used to bend an optical fiber manually at a port of a passive component of the passive optical network to cause signal leakage at a bent portion of the optical fiber;
- a non-transitory storage medium storing computer program instructions;
- and
- at least one processor configured to execute the computer program instructions to cause operations comprising:
- receiving indications of power losses at downstream and or upstream components caused by the signal leakage;
- and
- mapping at least one downstream component to the port based on the received indications of the power losses.
