Can fiber optic cables be sealed in plastic
Coating is an outer plastic layer applied to the cladding of a fiber optic cable for mechanical protection. Many NEMA and IP-rated potted seals, grommets and cable glands can shield fiber optic components from water spray or temporary submersion at a limited depth, but they fall short of a moisture-tight hermetic seal and will allow gases. However, the sealing method used inside these closures largely determines the long-term reliability of the fiber connection.

Plastic fiber optic communication distance
POF has been called the "consumer" optical fiber because the fiber and associated optical links, connectors, and installation are all inexpensive. Due to the attenuation and distortion characteristics of PMMA fibers, they are commonly used for low-speed, short-distance (up to 100 meters) applications in digital home appliances, home networks, industrial networks (,,, ), and car networks (). POF is typically effective for distances of up to 100 meters, making it more suitable for short-range applications. These efforts have led to the development of PMMA-core POFs with attenuation values below 150 dB/km at a wavelength of 650 nm. Giok Djan Khoe at Eindhoven University of Technology and Yasuhiro Koike, a polymer scientist at Keio University pioneered in high transmission speed over graded index. Limited Transmission Distance: One of the main drawbacks of POF is its limited transmission distance compared to glass fiber.
