Fiber Optic Network Test Set

Abstract

An optical fiber network test device comprising an actuator that is manually operable, without manual handling of optical fibers, firstly to direct light from a light path of the optical network so that test equipment associated with the network can be operated to test the quality of the said light path, and secondly to return the light path to its previous state after completion of the test.

Description

technical field [0001] The invention relates to an optical fiber network testing device used when testing the quality of light paths in an optical fiber network. It will be understood here that the expression "light path" is not necessarily limited to the transport of electromagnetic radiation in the visible range. Background technique [0002] Fiber monitoring methods are currently well established to allow testing of fiber links using a variety of Optical Time Domain Reflectometers (OTDRs), and these methods have been widely adopted to check the quality of long distance fiber links. With the ever-increasing deployment of fiber-to-the-home (FTTH), there is a growing need for low-cost monitoring methods to check the quality of fiber optic links within highly branched networks. From WO2007 / 096584 of TycoElectronicsRaychemNV it is known that for a technician who is installing a fiber optic drop cable from the main fiber optic loop to the subscriber's home, before completing t...

Problems solved by technology

In cases where it is later desired to test for faults within a highly branched passive optical network, without skilled personnel, a test pulse injected into the fiber from the central office of the telecommunication system is reflected back to varying degrees from all the different network branches, so that It is very difficult for central office OTDR equipment to identify which reflection is from which network branch
