Communications Specialties, Inc. (CSI) designs & manufactures the Pure Digital Fiberlink® line of fiber optic transmission systems for video, audio and data. In addition we design & manufacture products that bridge the gap between computer video and television video technologies, including the award-winning Scan Do scan converters and Deuce video scalers.

Fiber Optics

CSI offers an extensive selection of fiber optic transmission systems for video, audio and data.

The new Pure Digital Fiberlink® line employs all digital processing and signaling, delivering state-of-the-art performance at unparalleled pricing.

Included are systems for multiple channels of composite, component or S-Video, some combined with audio or data.

In addition, the all new, Pure Digital Fiberlink® Flex System provides tremendous flexibility by offering custom configuration of various signal types for transmission in one or two directions.

CSI also offers a variety of systems as part of the original Fiberlink® line.

These products employ traditional analog signaling techniques but, like the Pure Digital Fiberlink systems, offer customers a reliable, affordable fiber optic alternative to transmission over coax or copper wire.

Video Scalers

Our award-winning intelligent video scalers are a state-of-the-art alternative to traditional line doublers and quadruplers, offering superior performance and far more versatility at a substantially lower price.

Deuce converts NTSC, SECAM and PAL to a wide range of non-interlaced resolutions and refresh rates that match the native resolutions of LCD, DLP and plasma projectors and displays, resulting in a crisp, film-like image.

Deuce also may be used with CRT projectors and monitors for a greatly enhanced picture quality.

Scan Converters

For high-quality conversion of computer video to NTSC or PAL video, the Scan Do family includes the widest range of feature-rich and versatile scan converters on the market.

Every Scan Do model sets the industry standard for unsurpassed performance in its price range.

All models work with both VGA and Mac computers in all operating environments and support high resolutions and refresh rates.

Component output, optional SDI output, support for workstation resolutions (up to 1600 x 1280) and video processing controls are offered on some models.

Distribution Amps & Switchers

CSI offers the most extensive line of splitters available, with 12 application-specific models for VGA, 13W3, RGB, S-Video and Video.

These units may used to distribute a single video or computer signal to multiple monitors at distances of up to 250 feet.

CSI's Quadswitch® for VGA is a 4x1 switcher that allows four VGA video sources to be routed and switched to a single output.

QuadSwitch for VGA is an active switch, compatible with any VGA signal, and provides wide bandwidth buffer amplifiers and advanced sync processing.

All CSI Splitters and Switchers may be used as standalone units or as part of a rack system.

Extender Products

CSI's line of extension products facilitate the use of PCs from a remote distance. Designed to work with VGA and SVGA computers, they are ideal in a wide range of applications. The VGA ExtenderTM II and TwinSplit® E.D. are especially applicable to industrial environments, factory automation, R&D and security systems.


CSI offers both coax cable and fiber optic cable, in standard lengths with terminations already attached or in custom lengths with terminations priced separately. Fiber optic terminating kits are also available, for use with either single mode or multimode fiber.
