The Patton Model FOI-2170-ST provide complete electrical isolation for composite video communications. The units are compatible with several video broadcast standards. The units are transparent to all monochrome, color, and closed circuit video.
The FOI-2171 has an AGC (automatic gain control) to stabilize the video output for different fiber optic cable lengths. Adjusting the AGC potentiometer will also increase or decrease the overall scene brightness.
The units can be used in areas of high electrical noise or in and out of RF shielded enclosures. The fiber optic cable is not susceptible to interference caused by impulse noise, crosstalk, or EMI. Privacy of communications is also enhanced because the fiber optic cable does not radiate any emissions. In addition, fiber optic cable offers much longer transmission distances than traditional telephone line cord wiring.
Multimode optics on the units can extend the distance to 2km.
