Packed in rugged military style metal enclosures, the FOI-2172 Series support Unidirectional Composite Audio and Video over Fiber.

The FOI-2172 and FOI-2173 both provide complete electrical isolation for composite video and audio communications. The units are compatible with NTSC, PAL, and SECAM video broadcast standards. The units are transparent to all monochrome RS-170, color RS170A, and closed circuit RS-330 video. The FOI-2173 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 FOI-2172 can accept a wide level of audio input because clipping can be adjusted by the LVL potentiometer, while the FOI-2173 LVL potentiometer controls the volume. 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. FOI version units can be mounted in several redundant powering chassis; rack and wall mount options including Tempest and NEMA alternatives.

A typical link consists of a FOI-2172 connected to the Video Source and a FOI-2173 at the Video Monitor with a duplex fiber optic cable in between. The FOI-2172 is the Optical Transmitter, while the FOI-2173 is the Optical Receiver.
