7800DA2T-3G, 7800DA2T-HD

3G/HD/SD-SDI Bypass Protected Distribution Amplifier 1x6 / 2-1x3

Product ManualManual
  • VistaLINK® enabled
  • New
  • 3Gb/s enabled

The 7800DA2T Dual 3G/HD/SD-SDI Reclocking Distribution Amplifier provides high quality distribution of facility 3G/HD/SD-SDI signals. HD versions support SMPTE ST 292-1 and SMPTE ST 259 signals while 3G versions also support SMPTE 424M signals. This module features dual auto-sensing equalized inputs with unparalleled cable equalization, making it the most-cost effective and ideal solution for long cable run environments. The included dual bypass relays offer failure proof protection for critical paths.

For maximum flexibility, the module can operate in a dual input to three outputs each configuration or as one input to six output configuration.

The 7800DA2T is VistaLINK® enabled, offering remote monitoring, control and configuration capabilities via Simple Network Management Protocol (SNMP) giving the flexibility to manage operations, including signal monitoring and module configuration from SNMP capable control systems (Manager or NMS).

The 7800DA2T occupies one card slot and can be housed in the 3RU 7800FR frame which has a 15 slot capacity, or the portable 3RU 350FR frame which has a 7 slot capacity.
