The technique is based on the extraction of the temperature profile of the fiber by using a fiber Bragg grating (FBG) array. We propose here a liquid level sensor using a long period fiber grating (LPFG) in which direct liquid level measurement is carried out by utilising an LPFG, 100mm in length and a periodicity of 1mm. The LPFG was exposed to liquids with varying levels and the wavelength shift of a selected loss band.

The Fiber Development Index (FDI) tracks and benchmarks fiber development across 93 countries and territories. Especially since the COVID-19 pandemic, governments around the world now understand the social and financial benefits of investing in high-quality broadband networks. Since the pandemic, broadband access has become more important than ever for the consumer, with activities such as working/schooling from home, video communication, smart home use cases, and online entertainment becoming a standard part of everyday life in many countries. This has several advantages, from reducing the cost, internal compute power, and batery size of devices, to consistently using the latest software version and being able to support advanced technologies such as big data analyics and new cloud-based applications/use. As enterprises turn to digital technologies and ways of working, their capacity needs to increase exponenially over the next five years. The goal is to collect, store, and analyze data, generating valuable information for the organization to make faster, be er decisions.

In this paper we describe a probing method, referred to as Fiber Deflection Probing (FDP), for use on Coordinate Measuring Machines (CMM). Examples include the inner surfaces of micro-drilled holes, narrow gaps or complex free-form surfaces. The optical inspection technique offers a fast, contactless and wear-free way of measuring micro-structures and distances. Measurement of diameter and form of small holes is of great importance in applications such as fuel injector nozzles, fiber optic ferrules, wire drawing dies, holes in printed circuit boards and medical apparatus such as syringes, etc.

At its heart, a cable pulling winch is a specialised machine built for one crucial job: installing heavy electrical and fibre optic cables through ducts, pipes, or trenches. Hydraulic drives offer infinitely variable speed control, which is a critical benefit of using a hydraulic winch for cable pulling, as it allows for smooth starts and stops, preventing sudden kinetic shocks to the cable core. a tensiometeris incorporated into the conventional winch to limit the pulling torque of the winch to an amount below the tensional strength of the fiber optic cable. They supply the steady, controlled power needed to pull these cables over long distances safely and without damage. Working with client NGE, Thorne & Derrick have supplied a custom engineered Telecoms Cable Winch for the pulling and installation of fibre optic cables to the Liverpool Backhaul project – the cable winch will support the high-speed fiber infrastructure project which will connect all 6 local. Fiber optic cable is surprisingly strong, durable and pliable; however, several best practices should be followed to ensure a successful cable installation.

An Optical Time Domain Reflectometer (OTDR) is a specialized device used to test the integrity of optical fibers. It works by sending pulses of light into the fiber and analyzing the backscattered and reflected light to detect faults, measure loss, and determine fiber length. OTDR testing analyzes fiber optic cable performance from end to end by testing components along the cable, including connection points, bends, and splices.
