v2.12

New Features

• Documentation Updates:

  • Moved and updated documentation on equipment types and amplifiers for better organization and accessibility.
  • Improved documentation for script options, providing clearer guidance for users.
  • Added a list of collaborative PSE publications to the documentation.

• Enhanced Configuration Management:

  • The default values for EDFA configuration, including frequency range, gain ripple, noise figure ripple, or dynamic gain tilt are now hardcoded in parameters.py and are no longer read from the default_edfa_config.json file.
  • Introduced the ability to read a list of optional extra equipment files, allowing for more flexible configuration.
  • Users can now input their own default configuration file with the new default_config_from_json attribute for fixed and variable gain amplifiers.

Refactoring:

• Refactored methods to avoid unnecessary returns when modifying equipment dictionaries, streamlining the code.
• Defined defaults in common parts to be utilized by both CLI and API, enhancing consistency across interfaces.

v2.11.1

Release Notes

New Features

• Enhanced Warning System for Amplifiers: Added more warnings when user settings do not match the library, improving user awareness of potential issues.
• ROADM Excel Sheet Input Documentation: Comprehensive documentation has been added for the ROADM Excel sheet input, aiding users in understanding the input requirements.
• Per Degree Impairment Reading from Excel inputs: The program now supports reading per degree impairment from the ROADM sheet, allowing for more detailed impairment management.

Bug Fixes

• Plot Functionality: Resolved an issue where the plot function would overwrite the path variable, causing errors in plotting.
• Tilt-Target Default Value: Adjusted the handling of the tilt-target to maintain a None value when not specified by the user, rather than defaulting to 0 dB.
• UID Information in Logs: Restored UID information in warning logs for better traceability.
• Multiple Multiband Amplifiers: Fixed a case where multiple multiband amplifiers matching the sub amplifier type could cause issues.
• Offset Handling: Corrected the offset handling for reversed paths to ensure accurate calculations.
• Autodesign File Saving: Ensured that the autodesign file is saved correctly after the autodesign process.
• Linter Issues: Addressed various linter issues across multiple files, improving code quality and maintainability.

These updates enhance the overall functionality and user experience of the program. Thank you for your continued support!

Full Changelog: v2.11...v2.11.1

v2.11

This release enables the definition of a multiband amplifier site composed of multiple amplifiers, each for a separated band (a typical application is C+L transmission).

The release also includes autodesign for links (Optical Multiplex Section, OMS) composed of multi_band amplifiers. Multi_band autodesign includes basic tilt and tilt_target calculation when the Raman flag is enabled with the --sim-params option.

The spectrum is demultiplexed before propagation in the amplifier and multiplexed at the amplifier output before the propagation in the output fiber.

A preturbative Raman solution and an approximated GGN model are introduced for a faster evaluation of the Raman and Kerr effects, respectively. These implementations are intended to reduce the computational effort required for multiband transmission simulations.

v2.10

This release introduces detailed impairments for ROADMs:
ROADM impairments can be defined per degree and roadm-path type (add, drop or express).
Minimum loss when crossing a ROADM is no more 0 dB. It can be set per ROADM degree with roadm-path-impairments.

The transceiver output power, which was previously set using the same parameter as the input span power (power_dbm),
can now be set using a different parameter.

GNPy v2.9

GNPy v2.9

This release introduces a major refactor that enables
a clear separation of design and propagation functions.
It also introduces some behaviour correction and bug fixes.

• fix frequency scaling for fibers
• fix documentation on readthedocs.io
• possible to freeze a design and propagate on it without automatic changes
• checking for power saturation during design for all cases

GNPy v2.8

This new release adds some improvements in existing features,
and some new features:

• Spectrum assignment now supports multiple slots assignments
  in a single request.
• Logs are now generalized in the library instead of bare
  prints. Default verbose is "WARNING".
• Chromatic dispersion, effective area, Raman Gain coefficient,
  and nonlinear coefficient can now be defined with a scaling
  along frequency.
• Power equalization now enables defining a power offset
  in transceiver library to represent the deviation from the
  general equalisation strategy defined in ROADMs.
• Propagation now includes a latency calculation
• The library now supports of python 3.12

GNPy 2.7 -- OFC 2023

Starting with this release, the users can define a mixed load of channels to be propagated in the input spectrum. To better support real-life workloads, ROADM equalization strategies are now configurable, and there is also the usual set of bugfixes and performance optimizations.

GNPy 2.6

GNPy 2.6 — ECOC 2022

Greetings from a sunny day in Basel, Switzerland. This is a general bugfix release with some preparations for the upcoming features (mixed-rate simulations and the YANG interface). Please stay tuned while we stabilize these, and try out our patches under review:

GNPy 2.5

Hello from OFC 2022. Release highlights:

• CD, PMD and PDL tracking
• Improvements for OpenROADM
• Extended vendor support
• Performance optimization
• Bugfixes

If you're interested in what's coming next, be sure to check the patches and changes that we are currently working on.

GNPy 2.4

Hailing from the sunny Bordeaux, France, where ECOC 2021 is taking place, here's a new version of GNPy, an optical route planning library.

Released just three months after the v2.3, we've improved support of OpenROADM networks, fixed bugs, and extended our test suite. As was
previously announced, this is also the first release to require a more recent Python, the 3.8.

If you're interested in what's coming next, be sure to check the patches and changes that we are currently working on.
