Multi-channel Adjacent Channel Modulator (16-channel / 32-channel)
As the core device of analog headend systems, this unit converts AV/HDMI signals into RF radio frequency signals, supporting a global universal frequency range of 50~1000MHz. It comes with a built-in hybrid amplification module, high-efficiency heat dissipation system and stable power supply module, adopting a standard 19-inch rackmount design for easy installation.
Suitable for hotels, resorts, shopping malls, schools, hospitals and other premises, it enables customers to easily build multi-channel analog TV systems.
1. Signal Combiner (16-channel / 24-channel)
This professional signal mixing device adopts imported chips. It features low insertion loss (20±2dB) and high isolation loss (≥30dB), enabling interference-free mixing of multi-channel signals with clear and stable output, compatible with mainstream global analog TV frequency standards.
2. Optical Transmission Equipment (1310nm / 1550nm Optical Transmitters & Optical Receivers)
Supporting the analog headend system, these optical transmission devices feature long transmission distance, low signal attenuation and strong anti-interference performance.
