Description

Optical link performance calculator based on the Polynomial Closed-Form GN/EGN model (PCFM)

The main file is Matlab, the others are mostly MEX files, compiled for Windows/Intel systems and for Linux systems.

The software is capable of fully characterizing the GSNR of each channel of a multi-band, multi-span link, in the presence of ISRS and Raman amplification (both forward and backward).

Version 1.1: the graphical output of the provided use-case example has been improved. More information is provided, including a breakdown of NLI into SCI and XCI. A dialog lets you choose which span output, of the provided 10-span example of a C+L+S systems, you are interested in.

Version 1.2: several new system examples have been added. Now the full suite of examples include:

  • a 1000 km C+L+S system with Raman amplification optimized for throughput (same as in Version 1.1)
  • a 1000 km C+L+S system with Raman amplification optimized for throughput and GSNR flatness (new)
  • a 3000 km C+L system with Raman amplification optimized for throughput (new)
  • a 3000 km C+L system with Raman amplification optimized for throughput and for GSNR flatness (new)
  • a 7000 km C-band system optimized for throughput (new)
