Distinguishing features:

The ULTIMODE V-204DAO video converter uses the latest optical technology. It ensures transmission via single optical fiber of 4 video channels and 1 one-way RS-485 data channel (in opposite direction - from the video receiver to the video transmitter). It is possible due to the use of wavelength-division multiplexing technology (WDM) - different wavelengths (colors) of laser light to carry different signals, over one strand of fiber. It significantly lowers installation costs. The L2423 set contains 2 modules - video transmitter marked "T" and video receiver marked "R" - and 2 power supplies (12VDC/3A).

One of the devices transmits optical signal in the III transmission window (1550 nm), whereas the second uses the II window (1310 nm). Sensitivity of the receiver and output power of the transmitter is adapted to transmit information up to 20 km. In the case of shorter distances (up to 2 km), it is required to use additional 2dB attenuators by the receivers. They will protect them against "burning". Durable laser diode with Fabry-Perot resonator ensures the mean-time-between-failure (MTBF) at least of 100.000 hours (more than 11 years).

The set is compatible with NTSC/PAL/SECAM systems and ensures high quality transmission of live video over distances up to 20 km, much longer than those offered by standard devices. The possibility of sending control signal (RS-485) from the video receiver to the video transmitter allows to use PTZ cameras. Alarm channel provides possibility of using alarm sensors.

NOTICE!! It is not allowed to look directly at the fiber port when the device is plugged. The radiation invisible for the human eye can damage the retina!

ULTIMODE video converters are widely used for the transmission of CCTV signals over long distances and in areas exposed to harsh weather conditions. Optical fibers provide full electrical insulation and resistance to electromagnetic interference. Below there is a sample application of ULTIMODE converters.

Example application of ULTIMODE media converter

Video converters of ULTIMODE series can cooperate with all CCTV cameras. They are designed for indoor operation. Our offer also includes video converters with 1 video input and data channel (L2121), with 8 video inputs and data channel (L2821), and a model with 4 video inputs and data channel (L2421).
