Product Overview
The GQ3032N-16E1-6FE-2GE-V optical telephone terminal can transmit 32 voice channels, 16 E1 interfaces, six 100-Mbps ports (physically isolated), and two 1-Gbps ports (physically isolated) over fiber optic links. This device employs a dedicated digital multiplexing chip that integrates nearly all of its digital logic functions, significantly enhancing performance while reducing costs. The unit delivers excellent overall performance, operates stably and reliably, consumes low power, boasts high integration, features 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 networks and public networks in government agencies, the power sector, public security, the military, civil aviation, maritime operations, mining, highways, and more.
Product Features
1. Provides 32 telephone channels, 16 E1 interfaces, 6 Fast Ethernet ports (physically isolated), and 2 Gigabit Ethernet ports (physically isolated), with no compression and excellent voice quality.
2. The optical port supports multimode or single-mode, and can operate over a single fiber or dual fibers; it also features 1+1 optical protection.
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.
