Products Introduction: |
The optical transmission products mainly consist of GD8-12, GD8-17, and GD34-16 series optical transmission system. The Compactness optical transmission system with our independent intellectual property rights realizes transmission of digital, data and audio signal. They are widely used in telecom offices relay transmission of point-to-point switching system, and also be fit 2Mb/s transmission supported by fiber for base stations and data network, Telecom, etc.. |
Main Features: |
• High integration |
• Strong stability |
• High environment adaptability |
• Low power consumption |
• Easy maintenance Complete outstanding monitoring system |
Currently, the equipment contains of four capacities (8M,12M,16M,34M), four structures (wall-mounted type, desktop type, 19-inch cabin, 19-inch frame), so that it can satisfies customers' different needs for its functions and structure designs. In the central office, many system can be installed in one frame to realize the one point to multi-point transmission, with interfaces for RS232,V.35, 10/100M Ethernet, business and monitoring. The optical transmission includes working modes such as double-fiber single wave, single-fiber double wave. For easy maintenance, the equipment has the closing switch,
loop switch, as well as the end-to-end alarm indicator switch. |
