Temperature drift of fiber optic grating temperature sensor
In this paper we review the literature related to the long-term wavelength drift of FBGs at high temperature and provide our recent results of more than 4000 h of high temperature testing in the 900–1000 °C range. The regenerated fiber Bragg grating was produced by annealing a “seed” fiber Bragg grating recorded on SMF-28 hydrogen-loaded.

Principle of Fiber Optic Lossless Splitter
At its core, a fiber optic splitter relies on the principles of light reflection, refraction, and waveguiding to divide signals. A fiber optic splitter is a passive optical component that divides a single incoming optical signal into two or more outgoing signals, or combines multiple incoming signals into one. They are devices that split an incident light beam into several light beams at certain splitting. Bandwidth is shared amongst customers in a PON, and the bandwidth received by a customer is not related to the power received at the optical network terminal (ONT) as long as the power is high enough so the ONT can operate. It plays a vital role in optical fiber communication systems, especially in passive optical networks (PONs).
