An important application of plastic fiber is for various digital audio jumpers. In 1987, the Japan Electronics Industry Association established the digital audio jumper standard. At short distances of generally 5 meters, the signal is transmitted at 6Mbps between the power amplifier and the built-in digital analog converter and the digital audio such as the CD/MD/DAT player and the BS tuner. Plastic fiber is free from any noise and helps to create high-quality sound. TOSLINK is the abbreviation of Toshiba Link, and is also a standard optical digital audio interface, which is widely used by Japanese manufacturers in CD players and MD machines.
It is used to transmit digital audio signals (left and right channels or multiple channels) between various devices through a photoconductor that uses light as a carrier. TOSLINK can use plastic fiber to make plastic fiber audio jumpers. The commonly used standard PMMA core plastic fiber with a diameter of 1.0 mm and a numerical aperture (NA) of 0.5, and the jacket is (flame retardant) PVC, the color is black, red, blue and other colors, and the outer diameter of the jacket is mainly 2.2 mm; 4.0 mm; 5.0 mm; 6.0 mm, the length of the jumper is usually less than 10 meters.
High data transmission efficiency, small transmission loss, small bit error rate (about 2%). Eliminate radio wave and electromagnetic interference, non-conductive, stable performance, high confidentiality. Small size, light weight, soft and good winding, impact resistance. Easy to install and low cost.
Scope of application Multimedia audio system Digital cameras, camcorders, monitoring systems high-definition audio and video playback systems, MD players Internet TV, digital TV, 3D, 4D high-definition digital cinema, digital imaging systems Multimedia entertainment systems for automobiles, aircraft, ships, etc.
