Press Release Summary:
VT1930WDM Cohu video transmitter and data receiver mounts in Cohu 3920 i-dome(TM) cameras. Module replaces traditional power, data, and coaxial cable connections, allowing simultaneous transmission of video and bi-directional control data over one multimode optical fiber. Optical fiber eliminates ground loops while offering secure medium that is virtually impossible to tap into. Optical output of dome is compatible with company's VR1930WDM and VR1930WDM-CC receivers.
Original Press Release:
IFS Introduces Integrated Fiber Optic Video and Data Transmitter for Use in Cohu® 3920 i-dome(TM) Dome Cameras
New VT193OWDM COHU mounts directly in to a Cohu 3920 i-dome(TM) to
make Camera Fiber Optic Transmission Ready
Minneapolis, MN. May 22, 2003 - International Fiber Systems Incorporated (IFS), a leading manufacturer of fiber optic transmission equipment, has announced the introduction of its VT1930WDM Cohu video transmitter and data receiver. The VT1930WDM Cohu video transmitter and data receiver is designed for use in the Cohu 3920 i-dome(TM) dome system providing a fully integrated solution. This module mounts directly into the camera's dome unit, replacing the traditional power, data and coaxial cable connection. The VT1930WDM Cohu changes the 3920 i-dome(TM) camera from a standard coaxial cable connected dome to a direct-to-fiber connection. The optical output of the dome is compatible with the standard IFS VR1930WDM or VR1930WDM-CC receiver. The IFS VT193OWDM Cohu allows for the simultaneous transmission of video and bi-directional control data over one multimode optical fiber. It also utilizes FM fiber optic transmission for longer distances typically required for the i-dome's use in traffic management applications. When mounted in the Cohu i-dome camera, the IFS VT1930WDM Cohu can transmit video and data up to 69 kilometers. The unit supports the RS-422 data protocol that Cohu utilizes for camera pan, tilt and zoom control. In addition, an added feature built into the VT1930WDM Cohu is the addition of a contact-closure input. Now an additional device such as a dome tamper switch or internal pressure-loss alert can be added and its signal transmitted back to the monitoring location. This feature eliminates the need for additional wiring to support the contact closure alert.
The VT1930WDM-Cohu is designed for quick and easy installation into the 3920 i-dome(TM) dome unit and utilizes multimode
optical fiber. In addition, the VT1930WDM-Cohu transceiver is designed to be an integral part of the 3920 i-dome(TM) system,
there are no external electrical connections, and the fiber module requires no external power source and no additional hardware at the camera site. According to Nhu Dang, IFS Product Manager, "Installing the VT1930WDM Cohu is incredibly easy.
Simply press the fiber optic module directly into the data converter connector of the 3920 i-dome(TM) within the dome. Then,
tighten and connect the fiber optic cable, supply line voltage and attach the camera module."
The benefit to using optical fiber is to eliminate ground loops while offering a secure medium that is virtually impossible to
tap into. It also offers superior signal transmission even in environments that are subject to hostile Electromagnetic
Interference (EMI) or Radio Frequency Interference (RFI).
"With more installations utilizing a fiber optic backbone, many consultants are specifying equipment that is fiber ready.
We're very excited to add Cohu to the growing list of companies that IFS offers direct to optical fiber interfaces for," said
Bruce Berman, IFS ITS Sales Manager. "We believe that more and more camera and traffic control product manufactures recognize the benefits of signal transmission over optical fiber and will offer direct to fiber interfaces. We at IFS are ready to assist any or all that would like to take advantage of our expertise in fiber optic technology and product development." said Berman.
The VT1930WDM Cohu is designed for ease of use and to be maintenance free. These modules will operate in extreme
climates and have a operating temperature range of -40°C to 74°C. The unit can support distances of up to 42 miles (69 km)
And like all IFS fiber optic transmission products, the VT193OWDM Cohu is backed by the IFS exclusive Lifetime Product
Warranty. In the rare occurrence that there should be a problem, IFS will repair or replace the VTI930WDM Cohu for the life of the installation.
Established in 1989, IFS is at the forefront of advances in fiber optic technologies. The company offers more than 300 analog and digital fiber optic products for commercial and industrial applications, which include CCTV, access control, data transmission, fire and alarm system applications, intelligent transportation systems, facility and building automation, and broadcast systems.
