China took the lead in two key GPON equipment to achieve interoperability
A few days ago, the Ministry of CATR letter communications Standards Institute and work closely with China Unicom, the first time in the global GPON (Gigabit Passive Optical Network) equipment, two key OLT (Optical Line Unit) and ONU (optical network unit) the exchange, and developed the industry's first GPON interoperability testing instrument. This will greatly speed up the process of commercial GPON technology to reduce the cost of GPON equipment effectively to promote the size of the deployment of broadband optical access network. The two exchange more than two years after the test were the basis of the first three stages of testing and test the fourth stage of testing, now's GPON-based data services, VoIP services, multicast and integrated multi-service bearer in the GPON physical Layer four levels of interoperability. The test also has been the mainstream of seven at home and abroad GPON equipment manufacturers, chip manufacturers an active participation and cooperation.
At present, the broadband speed and broadband deployment of optical access network has become the basis of China's three major telecom operators of the development strategy, GPON technology because of its higher capacity, higher optical link budget, a good multi-service load-bearing capacity, improve security features such as the QoS will be one of the major FTTx technology. Since the recent period, GPON products, constantly improve the functionality and performance, the industry chain are becoming increasingly mature, and declining prices, interoperability issues have been resolved, have the conditions for commercial applications.
