The 7707CVT-8 is a VistaLINK® -capable, composite analog video fiber transmitter for broadcast quality video signals. This single card module accepts up to eight NTSC or PAL analog video inputs, performs analog to digital conversion and transmits them over a single fiber. The companion 7707CVR-8 Analog Video Fiber Receiver demultiplexes the signals and converts them back to analog form.
The fiber optic output of the 7707CVT-8 is available in an assortment of optical wavelengths, accommodating 1310nm/1550nm, CWDM and DWDM transmission schemes.
The 7707CVT-8 occupies two card slots and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.
Features
