Product Overview
The VGA‑series optical transceivers are independently developed by our company and feature proprietary intellectual property. Drawing on the strengths of comparable products both domestically and internationally, they have been designed to meet real‑world market demands as multi‑function VGA optical transceivers. This equipment can transmit, over a single‑fiber link, one VGA video signal with local video loop‑out, one keyboard‑and‑mouse channel, one pair of bidirectional 3.5 mm audio channels, one pair of bidirectional RS‑232 data channels, one reverse IR channel, and one reverse digital‑input/output channel. Featuring an SFP‑based optical module design, the device offers greater flexibility and practicality on site, allowing users to perform upgrades and maintenance themselves. It supports resolutions up to 1920×1080p at 60 Hz, with backward compatibility, delivering high‑definition images and distortion‑free long‑distance transmission—particularly well suited for demanding environments that require stringent performance in areas such as image quality, latency, EMI resistance, interoperability, stability, reliability, and consistency. The product has undergone extensive commercial deployment; field experience confirms its robust performance and seamless compatibility with signal and display terminals from leading brands. Installation is straightforward, maintenance is convenient, and it is ideal for large‑scale commercial applications. It is especially well‑suited for high‑performance remote computer operations, including broadcast‑grade recording, medical systems, projection‑based visualization, stage‑rental services, video conferencing, multimedia education, and municipal or military command‑and‑control scenarios. Lossless image quality and real‑time, high‑bandwidth fiber‑optic transmission deliver a user experience that closely mirrors local operation.
Product Features
1. Supports VGA video with local loop-out.
2. Supports one independent 3.5mm two-way audio channel.
3. Supports one KVM (keyboard and mouse) port.
4. Supports one bidirectional RS232 (or RS485) serial port for data transmission—choose one.
5. Supports one-channel reverse digital input.
6. Supports one-way reverse IR infrared functionality.
7. The optical port supports multimode or single-mode, and can be configured with either a single-fiber or dual-fiber LC connector.
8. Plug and play—no configuration required.
