Reflection Spectral Analysis of Fiber Bragg Gratings
We present a detailed experimental study of Bragg grating reflection spectra around the wavelength of λB = 1560 nm for different tilt angles set between the fiber and the phase mask. An optical Bragg grating is a transparent device with a periodic variation of the refractive index, so that a large reflectance (less precisely: reflectivity) may be reached in some wavelength range (bandwidth) around a certain wavelength which fulfills the Bragg condition where λ is the vacuum.

Fire Retardant Analysis Methods for Optical Cables
Flame retardant performance standards define the minimum requirements that optical fiber cables must meet to ensure adequate fire resistance. These standards specify test methods, performance criteria, and acceptance criteria for evaluating the flame retardant properties of cables. Corning Optical Communications manufactures quality flame retardant optical fiber cables for indoor applications, which comply with the requirements of the National Electric Code® (NEC® 2023) published by the National Fire Protection Agency (NFPA). Its structure is mainly composed of cable core, longitudinal covering a layer of two-sided synthetic mica tape outside cable core, inner sheath packed with ceramic sheathing. The cable has a design that ensures operation for more than 3 hours in fi es up to 1000 °C.

Analysis of Armored Optical Cable
During a series of towed array trials, it was observed that the metallic armoured cable had lost its circularity and became flattened during deployment and retrieval from ship.

Analysis of Relay Protection Failure to Trip
This paper focuses on developing a fault tracking model and process for the RPS-CB (relay protection system and corresponding CB), aiming to investigate the relationship between system faults and the incorrect operation of the PR and CB. Abstract A distance relay, which is widely used for pro-tecting a power transmission line as the primary as well as remote backup device, may be affected by the power dis-turbances such as power swings and post-faults. To improve protection quality, it is useful to identify and record perfo of electromechanical, solid-state, and digital relays. Specific system quality measurements include relay misoperations; relay failures to operate; relay delayed.
