GENERAL INFORMATION

The Pure Digital Fiberlink® 7223, 7225 and 7227 receiver units for
RGBHV video with stereo audio provide a combination of multiple
baseband outputs and optical loop-through capabilities for drop-and­repeat system configurations. All three models are compatible with any
transmitter unit within the 7220 Series. They operate at 1310 nm wave­length and work with either single mode or multimode fiber. Following
are general descriptions of each unit:

7223 Receiver: 4 baseband outputs of high-res RGB with stereo audio

7225 Receiver: 1 baseband output of high-res RGB with stereo audio,
plus one optical loop-through output

7227 Receiver: 4 baseband outputs of high-res RGB with stereo audio,
plus one optical loop-through output

The units’ all digital encoding delivers noise-free transmissions that
retain all of their initial parameters, regardless of fiber optic cable at­tenuation. System operation may be easily monitored using integral
LEDs on each unit that continuously signify the presence of baseband
video and audio signals.
