Designed for professional broadcast camera connectivity, this hybrid connector system integrates fiber optics, power, and signal transmission in one compact push-pull interface.
Designed for Next-Generation Broadcast Camera Connectivity
This SMPTE 304 hybrid connector system is engineered for HDTV and broadcast camera applications where optical signal integrity, power reliability, and mechanical robustness are critical. It supports secure, stable performance in both studio and outside broadcast environments.
The optimized internal structure reduces component count while maintaining SMPTE 304 interface compatibility, improving assembly efficiency and helping reduce installation risk.
Key Advantages
- SMPTE 304 interface compatible for HDTV camera and broadcast systems
- Push-pull self-latching for fast, secure mating and unmating
- Hybrid design combining fiber optic, power, and signal contacts
- Optimized structure with fewer components and improved internal routing space
- Easier fiber handling and fiber length adjustment during cable assembly
- Reduced optical epoxy curing time to speed up production
- Robust performance for field operation, vibration, and repeated mating cycles
Hybrid Contact Configuration
The connector supports a hybrid insert layout commonly used in broadcast applications:
- 2 × Fiber optic contacts (single-mode 9/125 μm)
- 2 × Power contacts (HV)
- 2 × Signal contacts (LV)
Precision alignment supports stable optical performance across frequent mating cycles and demanding environments.
