PORC-7223 3G/HD/SD SDI/DVB-ASI optical receivers with auxiliary HDMI output

PROFLEX™ PORC-7223 series 3G/HD/SD SDI/DVB-ASI optical receivers accept the single-mode optical fiber signal to demodulate the 3G/HD/SD SDI/DVB-ASI signal.
The optical input of PORC-7223 is based on the hot-swappable SFP module with the RX power monitoring facility.
The PORC-7223 module occupies one slot in the PROLFEX 1U/3U racks so that up to four receivers fit into a 1U rack and up to fifteen into a 3U rack.
The PORC-7223 receiver is WDM/CWDM/single-signal compatible.
The PORC-7223 is featuring the monitoring HDMI output with the OSD of the bar-graph audio level meters (quasi-peak and VU).

PORC-7223 simplified schematic diagram:

PORC-7223 accepts the optical signal on it's SFP RX module, which demodulates the input signal down to 3G/HD/SD SDI/DVB-ASI electrical form. The signal is processed by a video/audio processor. The video/audio processor deembedds the audio data streams. The audio may be monitored at the analog output. The 3G/HD/SD SDI/DVB-ASI video is available on two reclocked outputs.

Features:

  • 3G/HD/SD SDI/DVB-ASI compliance
  • electrical (3G/HD/SD SDI/DVB-ASI and HDMI) outputs are available simultaneously
  • user configurable reclocked or raw SDI/DVB-ASI outputs
  • hot-swappable SFP module as optical input device
  • the APD sensor modification available
  • high optical sensitivity
  • realtime optical RX power monitoring
  • signal loss indicator
  • EDH/CRC status indicators
  • automatic detection and indication of an embedded audio
  • audio group selection for the OSD bargraph audio level meter
  • bargraph audio level meter (quazi-peak and UV) OSD on HDMI monitor output
  • dBU or dBFS user-selectable scale with adjustable reference level
  • 3G Level B only: stream#1 or stream#2 selection for monitoring on HDMI output
  • compatibility with a single-signal, WDM and CWDM optical systems

Note: Always use the LC-type attennuator(s) at transmitters' output or receivers' input if the receivers' input optical power exceeds the -3dBm (for PORC-7223SFP) or -9dBm (for PORC-7223SFPA) level to avoid the receivers' sensor damage and sensitivity loss.

The indicators:

  • LOSS - lit when SDI input is lost
  • EDH/CRC/ASI ERROR MIN/HOUR - lit if two or more SDI EDH, 3G/HD SDI CRC or ASI errors were detected within one hour/minute interval
  • RX FAULT - lit when an optical input is at fault or no optical signal detected
  • ASI - lit when an input signal is recognized as ASI
  • EDH DET - lit when an input SDI signal contains the EDH packets
  • AUD DET - lit when an input 3G/HD/SD SDI has the embedded audio
  • the main graphical display shows the current parameter value. Contents is organized as twelve pages scrollable by the MODE button
