FS Optical Transport Network System

We focus on providing our customers the best technical support, engineering cost effective and
scalable solutions for metro and long-haul DWDM network.

Long-haul Transport for Multi-Service

Long-haul networks carry huge loads of information between cities, through mountains, or from coast to coast,
creating challenges to keep the signal clear and the loss minimal. FS.COM understands the challenge and strives to
help customers to solve these issues and build the most cost-effective networks.

Successful Case Studies

FS strives to provide more solutions with the highest standards of design, flexible application
and cost-saving products for you.
