7700ADA-ETSI
High Amplitude Analog Distribution Amplifier
The 7700ADA-ETSI High Amplitude Distribution Amplifier is a general purpose amplifier with an equalizing function for distributing a wide range of digital and analog signals. It has been designed to distribute pulses and signals up to ±3.5V amplitude as well as analog video signals. The 7700ADA-ETSI can transport ITU-T G.703 E12 (physical/electrical characteristics of hierarchical digital interface at 2048kb/s) signals. The 7700ADA-ETSI features one balanced equalized input with four outputs.
The 7700ADA-ETSI occupies one card slot and can be housed in the 1RU 7701FR frame which holds up to three single or 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.
