The 7707CVTA is a VistaLINK® capable, composite analog video and analog audio fiber transmitter for broadcast quality video and analog audio signals. This single card module accepts one NTSC or PAL analog video input with up to four analog audio inputs, performs analog to digital conversion and transmits them over a single fiber. The companion 7707CVRA Composive Video and Analog Audio Fiber Receiver demultiplexes the signals and converts them back to analog form.
The 7707CVTA-2 Dual Composite Video and Analog fiber transmitter is a dual channel version that digitizes and multiplexes two analog video and up to four analog audio signals and converts them to an optical signal for transmission. The companion 7707CVRA-2 Dual Composite Video and Analog Audio Fiber Receiver accepts a fiber optic input, demultiplexes the signals, performs D to A convertsion and output two NTSC or PAL analog video signals and up to four balanced analog audio signals.
The fiber output of 7707CVTA and 7707CVTA-2 is available in an assortment of optical wavelengths, accommodating 1310/1550nm, CWDM and DWDM transmission schemes. The 7707CVTA and 7707CVTA-2 occupy one card slot 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.
