OptiSystem 13.0.3 Release Notes
IMPORTANT - PLEASE READ ME
Installation Notes:
•
It is highly recommended that all previous versions of OptiSystem or
OptiSys_Design are removed from the Optiwave Software Programs folder before
starting the installation of OptiSystem 13.0.3
•
If the length of the installation directory path is too long, it can cause the installation
to fail. To avoid this, it is recommended that you not exceed the length of the default
installation path
•
Back up your data before installing OptiSystem 13.0.3 if you are a current user of
OptiSystem 12 or earlier. The software installation program supplies a complete set
of samples. These samples could overwrite the contents of the samples directory
from previous versions of OptiSystem found on your computer. If you have data in
the OptiSystem samples directory you want to keep, please make a copy of your
samples directory before installing OptiSystem 13.0.3 to avoid losing your data.
Minimum hardware and software requirements
OptiSystem requires the following minimum/recommended system configuration:
•
Minimum PC configuration: PC with Pentium 4 processor or equivalent with 2G MB
RAM.
•
Recommended PC configuration: PC with a clock speed > 2 GHz with 2-4 cores
(e.g. Intel i7 3rd/4th Gen, AMD Athlon/Athlon II) and 8MB RAM.
•
Operating Systems: Microsoft Windows 7 & 8.1 (32-bit/64-bit)
For optimum software performance, we recommend the 64-bit version of OptiSystem (64-bit version) installed on a Windows 7 (64-bit) or Windows 8.1 (64-bit)
operating system.
Note: OptiSystem 13.0.3 is only available in the 64-bit version. If you have a 32-bit
operating system please contact info@optiwave.com for further assistance.
•
400 MB free hard disk space
•
1024 x 768 graphic resolution, minimum 65536 colors
•
Internet Explorer 5.5 or higher (to enable VBScript functionality)
Application execution
•
When running OptiSystem under a Restricted User Profile, place all sample files in
the Restricted User's folder, or wherever the user has Read/Write access. It may
also be necessary to remove the Read-only flag from the file after the copy is made.
This has to do with file permissions - OptiSystem needs to open the file in a read/
write mode. Please contact your network administrator if you need assistance. Also
when opening an OptiSystem project it will be necessary to open OptiSystem using
the “Run as Administrator” command (right click to see this menu option command)
•
There are some MATLAB files (.m) included that are necessary to make the samples
work properly. Another important point - the path in the MATLAB search path (Main
tab of the MATLAB component) has to be updated with the path to the MATLAB files,
otherwise the samples will not work.
•
The path to the Scilab/bin folder has to be added to Scilab component (a parameter
field has been created for this purpose), otherwise the Scilab component library will
not work.
•
For the OptiSystem Help feature to function properly, Adobe Acrobat Reader must
be installed. To get the latest version please visit the Adobe website at http://
www.adobe.com/.
•
Some computers provide a power saving feature, Hibernation. If available, this
feature is controlled by opening Power Options in Control Panel. Clicking the
Hibernate tab, and then selecting the Enable hibernate turns it on. After the
computer goes into hibernation, it won't find the Optiwave protection key, and the
simulation will stop with a message that the protection key can't be found. Disable
the hibernation feature of the computer in order to avoid this problem.

Improvements were made to the User-defined IQ map
feature, including adding the ability to perform sweep
iterations of I-Q amplitude files. Issues related to the
loading and visualization of binary sequence data
(MxN parameters properties) were also fixed.

The calculation for Shot noise has been improved by
allowing for direct control over the time interval used to
calculate the photon count. Also the Noise parameters
properties have been re-organized, including a new
menu parameter which allows users to select the
source of the noise bandwidth for thermal and shot
noise calculations
Dual Port WDM
Analyzer
Visualizers/Optical
A new parameter option was added to allow users to
select the noise input option for the NF calculation:
EDFA with shot-noise limited input, From external
input noise
Multimode Generator

New parameters were added to the Multimode
Generator to allow for the generation of LP fiber
modes.

A minor update was applied to the naming of
parameters, specifically the “Peak Amplitude”
parameter was renamed to “Amplitude (wrt DC)”: NRZ

OptiSystem Version 13.0.3 issues and outstanding items
Components
•
Optical Switches. The control signal function for the optical switch components is not
working as defined. When the control signal is changed (from 1 to 0 or from 0 to 1),
the switch is not changing from its first state condition (of 0 or 1). This defect affects
the follows components: Digital Optical Switch, Optical Y Switch, Optical Y Select,
Ideal Y Switch, Ideal Y Select, Ideal Switch 2x2, Ideal Y Switch1x4, Ideal Y Select
4x1, Ideal Y Select Nx1, Ideal Y Switch1x8, Ideal Y Select 8x1, and Ideal Y Switch
1xN. Target release for fix: TBD
•
PIN and APD photodiodes. The PIN component was updated to include new
calculations and results for noise and transfer function analysis. These changes
were not captured for the APD component. Target release for update: OS 14.0.0
