Are the signals the same for the same optical splitter
Splitters share signals equally. Optical splitters play a crucial role in Fiber to the Home (FTTH) Passive Optical Network (PON) systems, efficiently distributing a single optical signal to multiple destinations. The split ratio and insertion loss are two key parameters defining their performance. As passive devices, they do not require an external power source to operate, relying solely on the properties of light transmission through fiber. Instead of running separate cables for each user or device, a central piece of equipment—called an Optical Line Terminal (OLT) —sends data down the line to multiple Optical Network Terminals.

What is the optical fiber head of a sensor
The sensor head is external to the optical fiber and is based on miniature components that are used to modulate the properties of light in response to environmental changes associated with physical perturbations of interest. Fibers have many uses in remote sensing. The light beam travels through the core by. Radiation absorption excites an orbital electron to a higher energy level. Heating the material enables the trapped states to interact with phonons and decay into lower-energy. A fiber optic sensor measures a physical quantity by modulating the intensity, spectrum, phase, or polarization of light traveling through the optical fiber system. Think of it like a photoresistor, which changes its resistance based. Intrinsic sensors (upper part of Figure 2) directly use an optical fiber as the sensitive material (sensor head) and also as the medium to transport the optical signal with the information measured.
