Product Overview
The GQ3008N-1FE telephone optical terminal can transmit eight voice channels and one 100 Mbps Ethernet channel over fiber optic cable. This device employs a dedicated digital multiplexing chip that integrates nearly all of the digital logic functions, thereby significantly enhancing performance while reducing costs. The unit delivers excellent overall performance, operates with stable and reliable operation, features low power consumption, high integration, a compact footprint, and is easy to install and maintain.
Guangqiao is one of the earliest domestic manufacturers of telephone optical transceivers. Our entire product line is independently developed, manufactured, and sold directly by our company. We possess core technologies, employing PCM pulse-code modulation to deliver crystal-clear voice quality and stable, reliable communication. Each voice channel is equipped with a three-level overcurrent and overvoltage protection circuit, setting our products apart from devices that use video‑optical transceivers, which often produce muffled audio and unreliable calls. Our solutions are widely deployed across major private and public networks, including government agencies, the power sector, public security, the military, civil aviation, maritime services, mining operations, and highway systems.
Product Features
1. Provides eight telephone ports and one 100 Mbps network port, with lossless compression and excellent voice quality.
2. The optical port supports multimode or single-mode, and can operate over a single fiber or dual fibers.
3. The device supports FXO and FXS interfaces: the FXO port connects to a PBX, while the FXS port connects to user terminals.
4. The voice interface supports caller ID and fax.
5. Compact size, aesthetically pleasing design, and easy installation and operation.
6. Enhanced status display functionality for easier maintenance and management.
