1、 Overview
The GD8-12, GD8-17, and GD34-16 series optical terminal products are high-performance small fiber optic transmission equipment independently developed by Guangzhou Tianwei Telecom Technology Co., Ltd., which can achieve the transmission of digital, data, audio, and other signals. The device is suitable for various capacity point-to-point switch inter office relay transmission, as well as several 2Mb/s transmission scenarios that require fiber optic support such as mobile base stations and paging stations. Users include telecommunications, mobile, China Unicom, China Netcom, Jitong, power, railway, water conservancy, oil fields, banks, etc.
The GD8-12, GD8-17, and GD34-16 series optical terminals were first launched in China in June 1995. They won the Guangdong Province Excellent New Product Award in 1998, passed the technical testing of the former Ministry of Posts and Telecommunications Optical Communication Product Quality Testing Center in June 1999, and obtained the network access certificate from the Ministry of Information Industry in November 2002.
The product has been listed as an online selection device for optoelectronic transmission by mobile, telecommunications, China Unicom, China Netcom, power, and new operators across the country.
2、 Main features
The characteristics of this device are high integration, stable performance, low power consumption, strong environmental adaptability, maintenance free, and a complete network management system that can centrally monitor the entire network. At present, this device series has four capacities (8M, 12M, 16M, 34M) and three structures (wall mounted, 19 inch chassis, 19)
The inch unit frame can meet the different usage needs of customers for device functions and external structures. Multiple systems can be installed in one frame at the local end, achieving
Point to multipoint transmission, with multiple interfaces such as audio, RS232, V.35, 10M Ethernet port, official and monitoring. Fiber optic interfaces include dual fiber single wave, single fiber dual wave, and single fiber single wave. For the convenience of maintenance, the equipment is equipped with a blocking loop switch and a terminal alarm display switch.
