The FOS line of fiber optic linked, power-by-light communications earplugs provides a communication earplug without electrical wiring and connections. Power and the communication signal are provided by an optical signal delivered through a fiber optic cable.
The fiber optic delivery is insensitive to EMI effects, does not radiate signal information and can be run over very long distances without electrical power for amplifiers or repeaters.
The fiber optic earplug is available for fiber optic operation at either 980nm or 1550nm.
The earplug speaker is driven with a provided driver in a class-d drive configuration using laser diodes of either 980nm or 1550nm to match the earplug wavelength chosen.
Slightly larger earplug with spectral response K. Standard fiber length 30m. Others available on request Uses earplug tips compatible with Shure Model E2 earplugs available in both foam and flanged eartips. Use requires driver Model FOSD900-Mono or Model FOSD900-Stereo
