2-CH DMX512 Fiber Optic Modem XLR 3-Pin Lighting Extender over Single Fiber 20KM FC/SC Interface Zero Delay Anti-Interference
The 2-Channel DMX512 Fiber Optic Modem is a professional solution for extending DMX512 lighting control signals over long distances using fiber optic transmission. Designed with a Transmitter (Console Side) and a Receiver (Lighting Fixture Side), it ensures stable and interference-free signal transmission even in complex environments. Compared with traditional copper cables, fiber optic transmission effectively prevents lightning damage, surge interference, and electromagnetic noise, making it ideal for large-scale and outdoor lighting systems.
★ Features ★
• 2-Channel DMX512 Control: Supports 2 independent standard DMX512 data interfaces with transmission rates up to 250Kbps for stable and reliable signal control.
• Standard XLR Interface: Equipped with 3-pin XLR connectors (female for transmitter, male for receiver), fully compatible with professional lighting systems.
• Ultra Long Distance Transmission: Supports up to 20KM over single-mode fiber.
• Strong Anti-Interference Capability: Fiber optic transmission eliminates electromagnetic interference, ensuring stable performance in complex environments.
• High-Level ESD Protection: Built-in ±15KV (HBM) and ±8KV contact discharge protection for industrial-grade reliability.
• Zero Delay Transmission: Automatic signal rate detection with real-time transmission ensures perfect synchronization of lighting effects.
• Point-to-Multipoint Support: Can be used with optical splitters to achieve one transmitter to multiple receivers for large lighting networks.
• Flexible Fiber Compatibility: Supports single-mode and multi-mode fiber without manual configuration.
• Wide Temperature Operation: Stable performance in extreme environments from -40°C to +85°C.
• Durable Industrial Design: Metal housing (145×100×35mm), strong and reliable for engineering installations.
