Using a unified global standard system, SDH applies the internationally accepted STM-1, STM-4, STM-16, STM-64 and other standard interfaces, allowing devices from different manufacturers to communicate over optical networks and eliminating the need to convert a digital signal to another standard for cross-regional communication.
Fully transparent circuit
IPLC provides customers with fully transparent, high-speed, end-to-end digital signal transmission service, carrying voice, video, IP and other services. Customers can select network equipment and protocols according to their specific business needs.
Effective Global Networking
China Telecom’s EPL network is built on partnerships with over 100 carriers worldwide and leverages terrestrial and submarine cable networks with access to more than 80 countries and regions across five continents
The digital circuit network is a synchronous transmission network that uses cross-connecting technology and circuit-switching technology to allow for flexible circuit scheduling and fast response to customer demands.
Improved network management
SDH frame structure sets aside a wealth of overhead bits (accounting for about 5% of the signal), greatly enhancing the network’s OAM capabilities.
Our network architecture is highly reliable, cost effective, and well adapted to the development needs of modern web applications.
Bottom-layer circuit, fault locating, and simple treatment enable easy maintenance and speedy business recovery.
Diversified speed rates
Communication speeds include 155Mbps, 622Mbps, 2.5Gbps and 10Gbps to support your specific applications.
