Transmission Systems

SDH (Synchronous Data Hierarchies) A high-speed international transmission system which capable of carrying digital signals at different capacities. SDH uses fiber optic links to take advantage of the high bandwidth and reliability of the fiber optic environment.

SDH SPEEDS;

STM1- 155Mbps

STM4- 622Mbps

STM16-2.4Gbps

STM64-10Gbps

PDH (Plesiochronous digital hierarchy) is a system for transporting data over telecommunication networks in large dimensions. This synchronous system is specifically designed to provide a simple and flexible network infrastructure. This system has changed significantly in terms of performance and cost in telecommunications networks based on optical fibers.

Some of the most enjoyable advantages of using SDH are;

1- Optical interfaces

2- Strong orientation capacity

3- In world standard format

4- Flexible synchronous structure

5- Reduced network density due to cross compatibility

SDH-PDH PRODUCTS;

Huawei OSN 3500

The OptiX OSN 3500 can be use in packet mode (MPLS / MPLS-TP based) or TDM mode. data service and conventional SDH service can be handled in the most appropriate way.The OptiX OSN 3500 delivers voice and data services on the same platform with high efficiency.
