Evertz 7708LT Wideband RF Fiber Transmitter, 88–3000 MHz

Evertz 7708LT Wideband RF Fiber Transmitter, 88–3000 MHz 

The Evertz 7708LT is a wideband RF-over-fiber transmitter that converts one 88–3000 MHz coaxial RF input into an optical signal for transmission over fiber. Its protocol-independent design transports extended L-band, off-air DTV and other RF signals regardless of modulation format.

The 7708LT provides manual gain control and automatic gain control, with an adjustable 0 to +30 dB range in 0.5 dB steps. A dedicated RF monitor output supports satellite signal peaking or additional signal distribution. Selectable 13/18 VDC LNB power, 22 kHz tone control, current monitoring and short-circuit protection are also included.

SmartMON technology relays incoming RF strength, LNB current and other operating data over the fiber link to a compatible receiver, eliminating the need for a separate monitoring connection. When installed with an appropriate frame controller, VistaLINK PRO provides SNMP-based remote monitoring and control.
