Product Overview

The GQ3032N-2GE telephone optical terminal can transmit 32 voice channels and 2 Gigabit Ethernet ports over fiber optic cable. This device employs a dedicated digital multiplexing chip that integrates nearly all of the digital logic functions, 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 form factor, 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 unstable calls. Our solutions are widely deployed across major private networks and public networks, including government agencies, the power sector, public security, the military, civil aviation, maritime services, mining operations, and highway systems.
