Modular Design

Modular design of all components in FONST Long Haul solution enebles flexible expansion of network node capacity as well as configuration through seamless, smooth upgrade.
 
Take FONST W1600 as an example, this node can realize smooth upgrade from 32 channels to 160 channels on the basis of the process of network construction. Also, it can achieve smooth upgrade of OLA > OMT > OADM > OXC. At the same time, smooth evolution from DWDM network to intelligent optical network ASON is supported. Concept of low-risk "Pay as you grow" is truly realized.
