FS WDM Solution Paves The Way to
Connect Multi-Type Fibres

Who Sends One Demand to FS for Helping?

The customer works for a Canadian ISP company, whose purpose is to support clients need to flawlessly orchestrate the delivery of the applications. His new project was to connect three sites which have a long distance between each other.

Q (The customer):
We are looking for a suitable solution to carry data over 2 links. What makes me confused is that there are two kinds of fibres in the first link. Will this affect the whole link?
A (FS):
Different fibres in the link means the signal would suffer from more signal degradation and optical dispersion. A cost-efficient solution is needed to solve this problem to keep the existing fibre working.

How to Meet the Customer's Demand?

Both G.655 and G.652 fibre can support DWDM. While G.652 has higher chromatic dispersion than G.655, which may cause the nonlinear effects in WDM systems, such as four-wavelength mixing (FWD). In this case, we fix the problem by emptying one band in the middle of each band when choosing the wavelengths of Mux Demux.

Key Point

For such a long distance, EDFAs are needed for amplifiying signals. While combined with optimized OSNR Raman amplifiers and high performance DCMs, amplification is achieved with reduction of nonlinear impairments and also signal quality is guaranteed.

DWDM system supports flexible expansion. For this project, more signals can be added to the link without deploying additional EDFAs or DCMs in the future. It provides a great degree of flexibility and significantly reduces OPEX and CAPEX.
