Hollyland Spares - SDI Cable (1000mm) (for Mars4k/400S Pro)

The Hollyland 1000mm SDI Cable (Model: HL-SDI1000) is an official factory-spare BNC video interconnect built specifically to feed high-definition digital signals to and from systems like the Mars 4K, Mars 400S Pro, and Cosmo C1 wireless video transmitters and receivers.

When rigging a camera, standard length SDI lines (like 3-meter or 5-meter cables) result in massive, hazardous loops of excess wire that can snag on limbs or equipment. This custom-length cable cuts down on-set clutter while maintaining professional-grade signal integrity.

Core Hardware & Signal Performance Features

• True 3G/6G-SDI Broadcast Throughput: Rated to comfortably handle high-bandwidth digital data rates. It carries everything from standard 1080p high-frame-rate feeds to compressed 4K data streams without dropping frames, inducing digital noise, or causing signal dropouts.

• Optimized 1000mm (3.28 Feet) Form Factor: The 1-meter length is the sweet spot for medium-scale camera rigging. It provides just enough slack to cleanly route from a camera body's SDI output through your stabilizer arms or cage structures up to a high-mounted Mars 4K transmitter, without leaving a dangerous bundle of extra wire.

• Low-Profile BNC Terminals: Fitted with slim-profile, male-to-male bayonet locking BNC connectors. This design makes it easier to twist-lock the cable into the deeply recessed, tightly clustered IO panels common on modern production monitors and wireless video docks.

• Industrial Strain Relief & Flex Protection: Both connector heads are encapsulated in molded rubber strain-relief boots. This shielding absorbs twisting and bending forces right at the termination joint, preventing internal core snapping during heavy run-and-gun operations.

System Interoperability

This broadcast patch cord is universally compatible with standard BNC connections but is specifically stocked as an official accessory for:

• Hollyland Mars 4K (TX/RX)

• Hollyland Mars 400S Pro (TX/RX)

• Hollyland Cosmo C1 (TX/RX)

• Professional production monitors, electronic viewfinders (EVFs), and cinema cameras from RED, ARRI, Sony, and Blackmagic Design.

Technical Specifications Matrix

On-Set Coaxial Routing Advice: To maximize the lifespan of your HL-SDI1000, avoid bending it at sharp 90-degree angles around tight camera cage corners. Coaxial broadcast cables contain a solid internal copper center conductor surrounded by insulation; kinking the cable tightly compresses this inner core, permanently changing its 75-ohm impedance profile and causing mysterious digital data errors or black screens. Wrap it in loose, gentle loops instead.
