Optical Cable Survey Instrument OCID

An Optical Cable Identifier (OCID) is a non-destructive instrument used to identify, trace, and verify specific optical fibers or cables in live networks without cutting or bending the fiber.Working PrincipleOCID instruments operate by detecting mechanical vibrations or tapping signals on optical fibers, converting these perturbations into measurable optical signal changes. Devices like the TFN GP200 and TK200 use the photo-elastic effect and coherent demodulation technology to transform external vibrations into visual waveforms (ECG or bar charts) and audio prompts, allowing technicians to identify target fibers quickly and accurately without service interruption or fiber damage . The laser beam is split into directional beams, and interference signals caused by vibration are processed into intuitive visual and audio feedback .Key FeaturesNon-destructive testing: No cutting, bending, or freezing of fibers is required .High accuracy: Capable of identifying specific fibers even in dense cable arrangements or long-distance networks up to 100 km (TK200-100/N), .Visual and audio feedback: Waveform displays and synchronized audio signals help technicians quickly locate the target cable .Connector compatibility: Supports FC/APC, SC/APC, PC/APC joints, and broken-end fibers .Environmental adaptability: Suitable for manholes, tunnels, aerial lines, pipelines, and other complex environments .Extended operation: High-capacity lithium batteries allow long field operation, often exceeding 10 hours .User-friendly interface: Touchscreen and physical buttons for reliable operation in various field conditions .ApplicationsOCID instruments are widely used in telecommunications and power communication networks for:Fiber identification in live networks: Quickly locating a target fiber without interrupting service .Maintenance and fault detection: Detecting and tracing fibers in dense ODF racks, cable trenches, or overhead lines .Construction and acceptance testing: Ensuring correct fiber connections during installation and network upgrades .Emergency repair and cut-over operations: Reducing risks of service disruption by providing fast, accurate identification .AdvantagesOCID devices provide a safe, efficient, and reliable solution for fiber network management. They minimize downtime, prevent fiber damage, and simplify the identification process in complex or high-density cable environments. By combining non-invasive detection, long-distance sensing, and intuitive feedback, OCID instruments have become essential tools for engineers and technicians in modern optical communication systems .
