Reliable, Long-Distance Camera Fiber Extension for Broadcast, Sports, OB Trucks, and Studio Production

Traditional SMPTE hybrid camera cables combine optical fiber and copper conductors in a single connection. While these are standard for professional cameras, long cable runs are heavy, expensive, and difficult to deploy. More importantly, SMPTE hybrid cables have distance limits that restrict flexibility when covering large venues, stadiums, campuses, or remote sites.

The MultiDyne SMPTE-HUT Series eliminates these constraints by enabling all camera signals—including video, audio, control, intercom, and tally- to travel over standard single-mode fiber between the camera and its control unit (CCU).

Depending on configuration, cameras can be powered locally or remotely using a short SMPTE hybrid cable at the camera end. The HUT Series allows camera and CCU separation of up to 10 kilometers using only two strands of standard single-mode fiber.

This solution enables SMPTE studio cameras to operate over long distances, reduces cable weight, streamlines deployment, and leverages existing fiber infrastructure.

Why Choose the MultiDyne SMPTE-HUT Series?

Conventional SMPTE camera chains work well for short distances. Over longer runs, however, hybrid cables present significant drawbacks.

Long SMPTE hybrid runs present several drawbacks:

• Heavy to transport
• Expensive to purchase
• Slow to deploy and retrieve
• Difficult to route through venues
• Vulnerable to grounding concerns
• Impractical for use with existing campus or building fiber

The SMPTE-HUT Series replaces long hybrid cable runs with lightweight single-mode fiber, drastically reducing weight and complexity.

A short hybrid cable connects the camera or CCU to the HUT device, while standard fiber handles the long-distance link. The CCU operates as if directly connected to the camera, preserving standard workflows.

This approach maintains familiar workflows while overcoming the weight and distance limitations of copper-based cabling.

Extend Camera Connections up to 10 Kilometers

The SMPTE-HUT platform enables camera-to-CCU separation of up to 10 kilometers over only two strands of single-mode fiber.

This extended reach makes the system ideal for:

• Stadiums and arenas
• Racetracks
• Golf courses
• College campuses
• Convention centers
• Large worship campuses
• Outdoor festivals
• Remote broadcast compounds
• Permanent venue fiber backbones

Instead of deploying thousands of feet of SMPTE hybrid cable, production teams can rely on existing tactical or installed single-mode fiber for the majority of the run.

Actual maximum distance and power delivery depend on HUT configuration, fiber quality, camera model, and the length of camera-end cabling.

Preserve Full SMPTE Camera Workflow

SMPTE studio-camera systems carry much more than the main camera image.

A typical camera chain may include:

• Camera video
• Return video
• Intercom
• Tally
• Camera control
• Genlock or synchronization
• Audio
• Prompter feeds
• Manufacturer-specific data

The SMPTE-HUT Series preserves the complete camera-to-CCU interface, not just basic video transport, ensuring all critical signals are maintained.

This allows camera operators and production teams to continue using the manufacturer’s standard workflow, including the original CCU and control interfaces.

Flexible Power Options: Powered and Unpowered Modes

The SMPTE-HUT system supports two primary deployment options for power delivery.

Passive or Locally Powered Mode

In passive mode, the camera is powered locally at the remote site.

This mode is ideal when:

• AC power is already available
• The camera uses local batteries
• The fiber distance is very long
• Remote power is not required
• The production wants the lightest possible optical link

Camera signals are transmitted via single-mode fiber while the camera is powered by local infrastructure.

Remote-Powered Mode

In powered mode, the camera-end device supplies power to the camera via a short segment of SMPTE hybrid cable.

Camera power can be delivered over up to 1,000 meters of 9.2 mm SMPTE hybrid cable, depending on system configuration and camera load.

This arrangement allows the long-distance backbone to remain standard fiber while maintaining remote camera power at the camera position.

HUT-APE Advanced Power Extension

The MultiDyne HUT-APE advances the SMPTE-HUT platform with enhanced remote camera power support.

It frees professional camera chains from reliance on long hybrid cable runs, enabling camera-to-CCU separations beyond 10 kilometers using standard single-mode fiber.

HUT-APE is particularly relevant when the production requires:

• Long-distance camera placement
• Remote camera power
• Reduced hybrid-cable deployment
• Lower truck and shipment weight
• Integration with installed venue fiber
• Faster setup and teardown

By relocating power conversion closer to the camera, productions can use lightweight fiber for the main run while retaining full camera-power functionality.

Minimize RF, EMI, and Grounding Issues

Copper conductors can introduce electrical issues over long distances, such as:

• Ground loops
• Electromagnetic interference
• Radio-frequency interference
• Differences in electrical potential

The SMPTE-HUT uses optical fiber for long-distance links, providing complete electrical isolation between locations.

Reducing RF, EMI, and grounding issues is a major advantage of HUT systems compared to long hybrid cable runs.

This benefit is especially valuable in stadiums, outdoor venues, temporary sites, and facilities with complicated electrical environments.

Leverage Installed Single-Mode Fiber Infrastructure

Many venues already contain single-mode fiber between:

• Control rooms
• Camera positions
• Equipment rooms
• Broadcast compounds
• Production studios
• Campus buildings

The SMPTE-HUT Series enables existing infrastructure to support professional camera chains.

Rather than installing new SMPTE hybrid cables, engineers can connect HUT devices directly to the existing fiber backbone and use short hybrid jumpers only where needed.

This approach significantly reduces installation costs and makes camera placement possible in locations that would otherwise be impractical.

Accelerate Setup and Teardown

Large hybrid camera cables demand significant labor to unload, route, safeguard, retrieve, and repack.

Replacing the long-distance segment with lightweight tactical fiber can reduce:

• Cable handling
• Crew time
• Truck weight
• Shipping weight
• Storage requirements
• Setup complexity

MultiDyne highlights accelerated setup and teardown as a key operational benefit of the SMPTE-HUT Series.

For mobile production companies and event crews, these time and labor savings accumulate significantly over a full season of events.

Reduce OB Truck and Cable Weight

Camera cabling represents a major weight factor in mobile broadcast operations.

Covering large venues often requires multiple long hybrid cables, each adding to the need for reels, cases, and transportation space. By using single-mode fiber for long runs, SMPTE-HUT significantly reduces the amount of heavy hybrid cable needed by:

• OB trucks
• B-units
• Flypacks
• Rental systems
• Air and ground shipments

MultiDyne positions the SMPTE-HUT platform as a solution to reduce cable weight and simplify transport logistics.

Flexible Optical Routing and Multiplexing

With optical long-distance transport, SMPTE-HUT signals integrate seamlessly into broader fiber infrastructures.

The two optical fibers can be routed through the EOS-4000 Optical Router. For greater efficiency, the FS-6000 CWDM system can combine signals from up to three camera systems onto a single fiber when properly configured.

These capabilities can help larger facilities:

• Centralize camera routing
• Use limited fiber more efficiently
• Reassign camera paths
• Build scalable venue infrastructures
• Reduce the number of dedicated strands

Optical system design should be tailored to distance, loss budget, connector type, redundancy requirements, and the number of camera systems supported.

Versatile Optical Connectivity

The SMPTE-HUT Series supports a range of optical connector options for maximum compatibility.

This allows the system to align with:

• Existing venue panels
• Tactical fiber assemblies
• Installed fiber backbones
• Broadcast truck interfaces
• Field-deployable fiber systems

Choosing the right connector type is critical for reliable performance and streamlined field operations.

Plug-and-Play SMPTE Camera Extension

The SMPTE-HUT platform integrates directly with existing cameras and CCUs, eliminating the need to replace any camera-control systems.

At the CCU end, a compact adapter accepts the hybrid cable. The long-distance connection then travels over single-mode fiber to the camera-end system.

This lets production teams retain familiar:

• Cameras
• CCUs
• Remote-control panels
• Intercom workflows
• Tally systems
• Return feeds
• Operational procedures

This familiarity reduces training and integration time compared to rebuilding the camera chain with third-party converters.
