DA-DHREO6803+D

Dual Fiber Transmitter, Coaxial In, Dual 1x4 or Single 1x8

The DA-DHREO6803+D/DX dual-channel distribution amplifier (DA) with fiber output provides two channels of coaxial HD/SD/ASI signal distribution with cable equalizing and reclocking and is designed for use with the 6800+™ modular core processing platform. This DA uses an SFP LC-type fiber dual transmitter with built-in electrical-to-optical (E-to-O) conversion.

The DA-DHREO6803+D is configured to function as a dual-channel DA with four outputs for each input (two 1x4). It can also be configured to function as a single-channel 1x8 DA with built-in automatic changeover (ACO). One output for each input is fiber. The DA-DHREO6803+D can be ordered without the SFP transmitter installed (+DX) to allow for expansion into fiber connectivity when ready.

The DA-DHREO6803+D provides 20 channels of 1x4 or 10 channels of 1x8 HD/SD/ASI distribution in a 2RU 6800+™ frame with low power consumption and non-inverting ASI compatibility on all outputs.

The DA-DHREO6803+D/DX can protect your signal path with built-in ACO. The user can select which input is designated as primary and which is designated as secondary. This further leverages your investment and allows a backup to feed directly on this DA.

The DA-DHREO6803+D/DX features broadcast-quality performance that exceeds SMPTE specifications. Software configuration of all parameters and remote indication of signal presence and alarms are standard.
