INTRODUCTION
The HD1500 / HD-3000 Series of Stand-alone Serial Digital Interface (SDI) Video
Fiber Optic Transport Systems for standard and high definition DTV have been designed to
ease the engineering and financial difficulties associated with the migration to DTV. The
system will transport digital signals from 143 Mbps up to 1.485 or 2.970
1
Gbps. The
supported standards include SMPTE 259M-C, SMPTE 292M, SMPTE 424
1
SDI, working at
270 Mbps, 1.495 Gbps and 2.970
1
Gbps, and compatible with DVB/ASI, and SMPTE 297M
interfaces at the defined rates. The units include a Digital Re-clocking DA and Repeater for
the SMPTE SDI standards mentioned above. For other standards, the signal is passed thru
without reclocking. For the electrical SDI interfaces, if you need to go beyond the 350-meter
limit, the HD1500 / HD3000 can be used to repeat and re-clock the signal multiple times with
minimum loss or jitter. The units include automatic cable equalization based on the data rate
detected. Applications include transmission links for high definition or digital television, studio
to transmitter; studio-to-studio, studio to CATV head-end and backhaul feeds from special
events. The transmit and receive units are available in portable or stand-alone and modular
configurations ideal for both field and studio applications.
FEATURES and OPERATION
TRANSMITTER, HD-1500-FTX or HD-3000-FTX
The transmitter module, designated by model number HD-1500-FTX or HD-3000-FTX,
includes a fiber output ST or SC connector and a serial digital video 75 Ohm input BNC
connector. The unit also includes a re-clocked 75 Ohm serial video output BNC connector
for a loop-through connection. The front of the module displays RATE LEDs for 270 Mbps,
1.485 Gbps, or 2.970
1
Gbps, Carrier Detect LED and Power LEDs that indicate the status of
the unit.
The rate LEDs indicate that a valid SMPTE rate is locked by the re-clocker PLL. The
Carrier LED indicates that a signal has been applied to the input. Carrier Detect is sensitive
to digital carriers from 19Mbps and above.
The Loop-through SDI output is an active regenerated version of the signal in the
transmitter SDI input that can be used to feed other transmitters or SDI complaint equipment.
RECEIVER, HD-1500-FRX or HD-3000-FRX
The receiver module, designated by model number HD-1500-FRX or HD-3000-FRX,
includes a fiber input with ST or SC connector, and two re-clocked serial digital video 75-
Ohm output BNC connectors. The front panel includes LEDs with the same functionality as
the transmitter, described above with the exception of Carrier Detect that is a PLL Lock
indicator for the fiber signal.
