Plastic optic fiber

Plastic optical fiber are light, soft and more resistant to damage (vibration and bending).Plastic fiber has excellent tensile strength, durability and small footprint.These advantages make the successful application of plastic Optical fiber in automobile especially important.A typical luxury car interior consists of at least a few kilometers of copper wire and copper cable, greatly increasing the weight and cost.The same is true of planes, trains and all other forms of transportation.
Due to the large diameter and numerical aperture of plastic optical fiber, the light conduction ability is large.Plastic optical fibers have much higher bandwidth capacity than copper transmission media (twisted pair and coaxial cable).The higher the transmission frequency, the lower the cost of using plastic fiber.
Plastic fiber cutting, wiring, bonding, polishing and other processing is easy.Due to its large diameter, plastic fiber installation and connection with devices, light sources, detectors, etc., is easy and low-cost, and can be performed by non-specialists.It takes no more than 1 minute to prepare the plastic fiber connection, and no special tools are required.Even the simplest scissors can be used to cut plastic optical fibers.The plastic fiber transceiver module uses a 650nm wavelength of red light, making it very safe for users to see and easily judge whether the connection is successful.In addition, the connection of plastic optical fiber is not sensitive to dust and debris stored in the end face.
Plastic optical fibers emit no radiation and are completely immune to electromagnetic and radio frequency interference and noise.This is especially important when it comes to video and audio streaming, which obviously affects the quality of the image and service.Plastic optical fibers can be placed in the same pipe as copper cable or in the same harness.Plastic fiber optics do not produce noise and will not negatively affect the current network.
The cost of POF systems is low.It is said to cost less than $20 per connection for home consumer electronics, home networking and cars including stereos, DVDS, VCRS, etc.So these devices can be bought in general stores.
Data transmission through plastic optical fibers can't be eavesdropped, making them ideal for high-security applications.
Although quartz fiber is widely used for long-distance trunk communication and fiber to the home, plastic fiber is referred to as "civilian" fiber due to the low total cost of plastic fiber, associated connection devices and installation.In the overall scheme of optical fiber to the home and optical fiber to the desktop, plastic fiber is the supplement of quartz fiber, which can jointly build an all-optical network.
Compared with quartz fiber, POF has the following advantages: low modulus, large core diameter (0.3-1.0mm), simple POF connector can be used for connection, even if the deviation of fiber connection center alignment is 30μm, the coupling loss will not be affected;Large numerical aperture (NA0.5 or so), light Angle up to 60°, quartz fiber only 16°, available cheap LED, and high coupling efficiency;Good flexibility, easy to process and use;Low loss window in visible region;Light weight;Low cost and processing expenses.
Compared with other transmission media, POF network also has obvious advantages in LOCAL area network system: POF is not sensitive to electromagnetic interference, no radiation, constant attenuation at different data rates, predictable bit error rate, can be used in electric noise environment;Its long size can reduce the requirement of tolerance control in joint design, so the net cost is low.[2]
