  • Spanish optical line terminals are resistant to high temperatures

    Spanish optical line terminals are resistant to high temperatures

    While showing excellent heat resistance at 200 ̊C, it has microbending resistance and dynamic fatigue properties superior to those of conventional heat-resistant optical fiber. We have developed a new heat-resistant optical fiber coated with ultraviolet (UV)-curable silicone resins. Fiber-optic high-temperature sensors are gradually replacing traditional electronic sensors due to their small size, resistance to electromagnetic. Optical line terminals, also called optical line terminations (OLTs), serve as endpoints for passive optical networks (PONs). They convert electrical signals from equipment managed by a service provider to fiber optic signals readable by a PON. The OLT is responsible not only for transmitting data from the core network to user terminals but also for managing bandwidth.
