An Upgrading to 10G DWDM Network Solution for ISPs to Access Multi-type Business


With the increased service needs, like HD video and live streaming, fiber exhaust, and layered bandwidth management, many original networks couldn't meet the demand in the access network and network capacity for ISPs. FS’s client, one famous ISP (Internet Service Provider) wanted to upgrade its WDM network and the access services capability simultaneously in order to offer a better experience for their customers.


  • The main problem of the client was that they needed to improve the ability to accommodate more access services and expand the bandwidth of the existing network infrastructure. Equipment compatibility and network management simplified were also needed to take into consideration.


In this multi-sites DWDM network upgrade solution, FS M6200 series multi-service WDM platform was deployed in the data center of three sites, which used 40CH DWDM Mux Demux to expand existing network capacity and could realize up to 400G data transmission.

The distance between the three sites was 90km and 110km, the optical signal dispersion of them must be considered. In this solution, the pre-amplifier, booster amplifier, and dispersion modules were used to balance the optical link power and ensure a stable transmission performance.

Additionally, OLP (optical line protection) was used to protect the whole link. And the M6200 series adopted a whole set of software operating systems, which could simplify the network operation and maintenance. Its high availability helped to upgrade the legacy network and allowed adding multiple services for different applications.


Customer Benefits

  • Multiple service access capability : this solution deployed FS M6200 series multi-service WDM platform, which used unified switching of multiple protocols like 10G WAN/LAN, Ethernet 100M, STM-16/64, OTU2/2e, etc., it could not only achieve the access, aggregate of the Ethernet service but also take various applications demands thoroughly of customers into consideration.

  • High-reliability WDM network solution : the core units like power supply and network management unit are 1+1 redundant to protect the whole link and ensure stable data transmission.

  • Unified & simple network management : the powerful management capability could offer fault, alarm, and configuration management to provide effective assurance for daily management and maintenance so that faults could be handled in a timely manner.
