How HD-SDI Video to Fiber Transmission Works

The HDSDI-11 system uses a transmitter and receiver connected by a fiber optic link.

The transmitter accepts the HD-SDI video signal through a 75-ohm BNC input and converts the signal for optical transmission. The transmitter also provides a local SDI output for monitoring. At the opposite end of the fiber link, the receiver converts the optical signal back to HD-SDI for connection to a monitor, DVR, or other video equipment.

The system also provides RS-485 return data from the receiver toward the transmitter. RS-485 data is supported at rates up to 300 Kbps.

This makes the HDSDI-11 useful for installations where high-definition video and return control data need to travel between two locations over fiber.

HD-SDI Fiber Optic SFP Options

The HDSDI-11 uses interchangeable fiber optic SFP modules, allowing the system to be configured for different fiber types and transmission distances.

Required fiber optic SFP modules are sold separately. This allows the appropriate optical module to be selected based on the application's fiber type, wavelength, connector configuration, and required transmission distance.

These SFP configurations are specified in the HDSDI-11 product datasheet.

HD-SDI Video Interfaces

The HDSDI-11 uses standard BNC video connections and LC optical connections.

The transmitter provides one HD-SDI input and one local video output, while the receiver provides two HD-SDI video outputs for connection to monitoring or recording equipment. The system uses 75-ohm BNC video interfaces.

• Video input: BNC, 75 ohms
• Video input channels: 1
• Transmitter local output: 1
• Receiver video outputs: 2
• Nominal video level: 0.8 Vp-p
• Input cable equalization: up to -30 dB of cable loss
• Re-clocked rates: 270 Mbps, 1.485 Gbps, and 2.98 Gbps
• Optical connector: LC
• RS-485 connection: screw terminal strip

HD-SDI Standards Supported

The HDSDI-11 supports a range of digital video standards used in professional video and surveillance applications, including:

• SMPTE 424M
• SMPTE 292M
• SMPTE 259M
• DVB-ASI
• ITU-R BT.601
• ITU-R BT.1120

The system supports video data rates from 270 Mbps through 2.97 Gbps, providing compatibility with a range of SDI video applications.

Standalone or Rackmount Installation

The HDSDI-11 can be deployed as a standalone transmitter and receiver system or installed in a centralized FVC18 18-slot rackmount chassis.

The hot-pluggable design allows modules installed in the FVC18 chassis to be replaced without powering down the chassis, simplifying maintenance and system expansion.

This provides flexibility for both individual HD-SDI fiber links and larger video transmission installations.

Applications of HD-SDI Over Fiber

HD-SDI fiber optic transmission is well suited for applications requiring reliable, high-quality digital video over longer distances.

Typical applications include:

• Video surveillance
• Professional video monitoring
• Broadcast and production facilities
• Digital video distribution
• Control rooms
• Recording systems
• Remote video monitoring
• Security systems
• Large-screen video displays
• Government and industrial video systems

The fiber optic link is particularly useful when video must be transmitted beyond the practical distance of conventional copper cabling or through electrically noisy environments.
