Unidirectional Composite Video

Model #: FOI-2170 | FOI-2171

FOI-2170

The FOI-2170 and FOI-2171 both provide complete electrical isolation for composite video 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-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. A typical link consists of an FOI-2170 connected to the Video Source and an FOI-2171 at the Video Monitor with a duplex fiber optic cable between them.

Flexible Mounting and Powering Options

The FOI-2170 and FOI-2171 are part of the FOI line of products designed for ruggedized mil applications. They are housed in the familiar FOI shielded can enclosure. For standalone applications they can be powered by adding a PSQ‐2909 AC supply or a PSQ‐2920 DC power supply (not included). Optionally, up to 8 FOI units can be mounted on CMA chassis adapters and installed in an RMC‐3101 or RMC‐2101 rack mount chassis. The units are powered redundantly by a common back plane connection.
