DA-DHROO6804+D
The main features for the DA-DHROO6804+D are listed below. Figure 1-8 shows
a basic signal flow diagram for this distribution amplifier module.

 Operates with dual slot, 3SFP optical distribution amplifier back module (see
page 14)
 Passes signals at data rates from 5 Mb/s to 3 Gb/s
 Four selectable channel configurations:
 1×8_ACO: 1 optical input (In_A) to 4 electrical outputs and 4 optical
outputs with auto changeover
The optical signal on In_A is distributed to 4 electrical outputs and 4
optical outputs. If the signal at In_A disappears, the outputs are switched
to In_B (if an optical signal at In_B is detected).
When the signal is reappears In_A, the outputs are automatically switched
back to In_A from In_B.
 1×8_ In_1: optical In_A to four electrical outputs and four optical outputs
 1×8_ In_2: optical In_B to four electrical outputs and four optical outputs
 2_1×4: 2 independent 1×4
 Optical In_A to OUT_A1/A2 (optical outputs) and A3/A4 (electrical
outputs)
 Optical In_B to OUT_B1/B2 (optical outputs) and B3/B4 (electrical
outputs)
 Input signal presence detect and report
 Optical input status for optical input (by CCS)
 Reclockable for 270 Mb/s, 1.485 Gb/s, or 2.97 Gb/s SMPTE and DVB-ASI
signals
 Three selectable reclocking modes (automatic, manual, enforce bypass)
 Automatic bypassing reclock stage if not relockable
