Fiber Coverage

 

Our fiber optic network is designed based on SDH & Ethernet over SDH. And we are the almost nationwide connectivity provider. Our SDH netrwok is a reliable STM-1/STM-4 optical transmission system, which is fully compliant to ITU-T and SDH recommendations. It enjoys high flexibility, modularity and scalability in configurations.

 

SDH has powerful network management system that supports

 

  • Supporting multiple network configurations: Point to point, chain, ring, star, tree, multi-ring, ring crossing, etc.
  • Providing sub-network connection protection and 1+1 multiplex section protection
  • Providing multiple service interfaces of E1, T1, E3, DS3, STM-1o/e, STM-4, 10M/100M Ethernet interfaces, etc.
  • Huge interface capacity: Up to XXX (i.e. 128) T1 interfaces, up to XXX E1 interfaces, up to 12 E3 interfaces, up to 16 T3 interfaces, up to 16 100Base-T interfaces, up to 4 STM-4 interfaces, up to 10 STM-1 interfaces
