The Fujinon CFC-990 is a high-precision, heavy-duty flexible mechanical drive cable specifically engineered for professional broadcast and studio operations. It provides a direct, zero-latency mechanical linkage between a Fujinon broadcast lens control panel or manual focus unit and the servo drive unit on compatible Fujinon HDTV box lenses, such as the HA, XA, and ZA series. This cable transmits rotational torque to control the lens's focus, zoom, and iris functions with absolute tactile feedback, allowing camera operators and focus pullers to execute smooth, repeatable adjustments. Its robust, multi-core steel wire construction within a durable, flexible outer sheath ensures reliable torque transmission even when the cable is repeatedly bent or routed through tight spaces on a camera rig, studio pedestal, or outside broadcast vehicle.

The cable is designed for maximum durability under continuous professional use. The outer jacket is made from a high-grade, abrasion-resistant polymer that protects the internal drive shafts from physical damage and contaminants like dust and moisture. Each end of the cable is terminated with a proprietary, precision-machined brass connector that features a threaded, screw-lock coupling mechanism. This positive locking system guarantees a secure connection that will not vibrate loose during transport or operation, which is critical for maintaining precise control. The connectors are keyed to ensure proper alignment and to prevent damage to the delicate gearing within the lens and control unit.

As a critical interface component in high-end broadcast systems, the CFC-990 enables the ergonomic placement of control surfaces away from the camera body. This allows operators to position a lens control panel on a tripod handle or a focus controller on a follow-focus rig for optimal comfort and efficiency during long shoots. The purely mechanical nature of the cable makes it completely immune to electromagnetic interference and requires no power, offering fail-safe operation. By ensuring a direct, reliable, and high-fidelity mechanical connection, the Fujinon CFC-990 upholds the standard of precise, responsive, and intuitive manual control that professional cinematographers and broadcast engineers demand for critical focus and zoom operations.
