5 FIBER OPTIC VIDEO TRANSMITTER AND RECEIVER
This section describes all the controls and connections of your fiber optic device.
5.1 Getting to Know Your 611T and 611R fiber optic transmitter and receiver
The Kramer 611T is a high performance composite video to fiber optic transmitter, and the 611R is its
receiving unit which converts the fiber optic signal back to standard video. Transmission via fiber carries
signals much farther than ordinary coax cable, and is lighter. Another advantage of fiber transmission is
complete ground isolation between source and display.
A simple system consists of a 611T located at the video source, and a 611R at the display device.
Standard units use “multimode” technology allowing transmission up to 5 kilometers. A 12V power supply is
provided with each unit. Both units are part of the Kramer TOOLS family of compact, high quality, and cost
effective solutions for a variety of applications.
Front/rear panel features of the 611T are described in Figure 1 and Table 1.
