The PMMA Plastic Optical Fiber jacketed in PE, PVC, or PUR sheaths serves to shield the PMMA Fiber Core from harsh environments in Series of Duplex PMMA Plastic Optical Fiber-POF Cable.
For transmissions over 100 meters or less, the DC series POF Duplex cable is typically used in place of well-known brands.
The Global Halogen-free Duplex POF Cable market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Richard Skipper came up with the first commercially available thermoplastic LSZH material for cable jacketing, and Raychem Corporation patented it.
This invention solved the problem of incorporating enough inorganic filler, aluminum trihydrate (ALTH), into the right thermoplastic matrix to suppress the fire and allow for the formation of char.
This reduced the emission of poisonous carbon gases as well as smoke and carbon particles while still maintaining the electrical insulation properties and physical properties needed by the final application.
Aluminum trihydrate (ALTH) is still the most widely used inorganic filler for achieving flame retardation. This material goes through an endothermic chemical reaction in the event of a fire. When the compound reaches a certain temperature, it absorbs heat energy and releases steam.
It is absolutely necessary for the polymers that carry the filler to decompose at roughly the same temperature. The steam prevents the evolved gases from burning and contributes to the formation of a char layer that shields the remaining material and collects particulates.
The base polymer is also replaced by the high level of filler, which reduces the total amount of fuel that can be burned.
Low smoke zero halogen link significantly lessens how much harmful and destructive gas produced during ignition.
A zero-halogen low-smoke cable releases smoke at a slower rate and with less optical density when burned. A low-smoke cable is desirable during a fire because it reduces the amount and density of smoke, making it easier for occupants to escape a room and increasing the safety of firefighting efforts.
Aircraft, rail carriages, tanks, subsea and offshore installations, submarines, and ships are all common applications for this kind of material. It is also used a lot in the rail industry, where track signal or high voltage wires need to go through tunnel systems.LSZH cables have also been and will continue to be used in the nuclear industry.
LSZH cables have been produced by major cable manufacturers for nuclear facilities. LSZH cable will almost certainly be used a lot when building new nuclear plants.
Because of this, there will be less of a chance of toxic gases building up in areas where employees are working, and there won’t be as many corrosive gases in computer-controlled systems, which will make it less likely that fire will damage wires and cause a short circuit.
