INTRODUCTION 1

INTRODUCTION

The HD3500 Series of stand-alone SMPTE 3G video High Definition Serial Digital
Interface (HD-SDI) with audio and data transport systems extends the range limits of
electrical interfaces, and combines audio and data along with the HD-SDI signal in a single
optical fiber link. The system will transport digital signals from 5 Mbps up to 2.970 Gbps,
analog audio, AES digital audio, serial data, intercom, tally, and General Purpose I/O (GPIO)
signals.

Applications include transmission links for high definition or digital television, studio to
transmitter; studio-to-studio, robotic studio cameras, studio to CATV head-end and backhaul
feeds from special events. The transmitter and receiver units are available in portable or
stand-alone and modular configurations ideal for both field and studio applications.

FEATURES and OPERATION

The HD3500 supports all popular standards for digital video transport such as SMPTE
259M-C, SMPTE 292M, and SMPTE 424, working at 270 Mbps, 1.495 Gbps, and 2.970
Gbps respectively. In addition, the HD-SDI interface also will transport signals compatible
with DVB/ASI, and SMPTE 297M interfaces at the defined rates. The units include a digital
reclocked DA and repeater for the SMPTE SDI standards mentioned above. For other
standards and rates, the signal is automatically or manually passed thru without reclocking.
For the SDI/HD-SDI input, the units include automatic cable equalization based on the data
rate detected.

Separate from the SMPTE video transport, the HD-3500 also transports 4 analog
audio channels with maximum configurable levels of 4dBu, 10dBu, 16dBu, or 28 dBu; 2
digital AES pairs up to 96Khz that cross convert with the 4 analog channels; and a
bidirectional stereo channel for intercom applications with maximum level of 4dBu. The
system also supports 4 GPIO bidirectional channels with open collector inputs capability and
relay contact for the outputs; 1 bidirectional tally IO with open collector input and contact
relay output; and 3 bidirectional serial data channels compatible with RS232 or RS422
transport up to 3Mbps.

To accomplish SMPTE video with bidirectional audio and data transport, 3
wavelengths are multiplexed over a single fiber using a CWDM module, a 1310nm optic used
for SMPTE video, and 1490nm and 1550nm optics are used for the bidirectional audio and
data transport. The SMPTE video input and output use standard BNC connectors while the
audio and data use a DB44 connector with either a special breakout cable assembly or a
diving board. See appendix A for pin-out information.

FEATURES and OPERATION 2

TRANSMITTER, HD-3500-FTX

The transmitter module front and back is shown in figure 1. In the back and from left to
right it includes a DB44 connector for all audio and data IO; two serial digital video SMPTE
75 Ohm input BNC connectors, one for input and one for reclocked SDI / HD-SDI output loop;
a single fiber output ST or SC connector; and a DC Jack power connector. In the front of the
module we see 3 SMPTE SDI lock LEDs for 270 Mbps, 1.485 Gbps and 2.970 Gbps rates;
SMPTE SDI CD (Carrier Detect) LED; 2 audio status LED that indicate channel 1 and 2 level,
peak, or AES presence; 6 data activity LEDs to indicate TX and RX activity in the 3 data
channels; a tally on indicator LED; a link status LED; and a power LED.

SMPTE video transport

5Mbps to 3Gbps. The SMPTE video signal is connected to the 75 ohms BNC input connector
in the back. Signals with rates from 19 Mbps to 3Gbps are then equalized. Equalization is
used to help open the digital video eye pattern that may have been closed or deteriorated
due to long coaxial cable runs. After equalization, the signal is reclocked and sent to the fiber
transport and to a 75-ohm loop output, which is the second BNC connector in the back. The
front rate LEDs indicate that a valid SMPTE rate is locked by the re-clocker PLL. The Carrier
Detect (CD) LED indicates that a signal has been applied to the input. Carrier Detect is
sensitive to digital carriers from 19Mbps to 3Gbps.

Non-SMPTE transport via the SMPTE interface

indicated earlier; however, other signals may need special settings. The SMPTE video input
has a feature that automatically mutes signals as noise or other signals under 19Mbps. If you
need to transport these signals, the auto mute feature can be disabled changing the jumper

The HD-3500-TX receives SMPTE video or other properly encoded data signals from

The HD3500 will operate normally by default with SMPTE video signals at the rates
