This document provides information about the Infinova 3793 series ten-node optical terminal unit, including product description, ordering information, installation guide, and system connection diagram. The product is a high-quality and high-reliability fiber optic transmission system that can transmit 10 channels of digital encoded video signals, supporting up to 16 channels of independent bidirectional data and 2 channels of shared reverse data. Each node transmitter can transmit up to 5 channels of video, 4 channels of independent bidirectional data, and 2 channels of shared reverse data. The system also supports 10/100M adaptive Ethernet signal transmission.
The Infinova 3793 series ten‑node optical fiber terminal provides high‑reliability transmission of video, data and Ethernet over single‑mode fiber. Each transmitter can handle up to 5 video channels, 4 independent bidirectional data channels and 2 shared reverse data channels, while the receiver supports up to 10 video and 8‑16 data channels depending on the model.
The manual details safety precautions, mechanical installation, power requirements, panel connections, system wiring, network management functions, keyboard switching setup, and optional optical‑path protection. It also lists ordering information for various transmitter (TA) and receiver (RA) configurations and provides wiring diagrams for both keyboard and network‑based configuration. This manual is written in Chinese.
| Fiber type | 9/125 µm single‑mode fiber |
|---|---|
| Transmitter power supply | 1.5 A @ 24 V AC (120 V or 220 V input) |
| Receiver power supply range | 110 V – 230 V AC |
| Supported interfaces | RS232, RS422, RS485 (full/half‑duplex), Manchester/Biphase, 10/100 M Ethernet |
| Maximum independent data channels per transmitter | 4 bidirectional data channels |
| Maximum shared reverse data channels per transmitter | 2 channels |
The system supports up to ten nodes, with ten transmitters and one receiver chained together.
The transmitter uses a 1.5 A @ 24 V AC plug‑in power supply, compatible with 120 V or 220 V input.
Press a numeric key (0‑9) followed by the Run key; for video switching press ‘1’ then ‘Run’, and select the source with ‘Mon’ and ‘Cam’ keys as described.
If a transmitter fails, the system automatically bypasses the faulty unit, keeping the rest of the link operational.
