The latest version of OptiSystem features a number of requested enhancements to address the design of passive optic network (PON) based FTTx, optical wireless communication (OWC), and radio over fiber systems (ROF).

Comprehensive Multimode Library

The Multimode Component Library of OptiSystem 6.0 includes an exciting new feature empowering users with the option to load multimode fibers measurements of modal delays and power-coupling coefficients using the Cambridge file format. As result, users now can calculate the MMF link frequency responses faster allowing extensive statistical modeling of multimode-fiber links.

Sophisticated Amplifier Library

Design a variety of waveguide and fiber optic amplifiers using OptiSystem. Determine the tradeoffs between EDFAs, EYDFs, EYDWs, YDFs, SOAs and Raman amplifiers cost and performance. OptiSystem 6.0 automates the analysis of laser pulses by plotting autocorrelation and FROG (Frequency Resolved Optical Gating) graphs directly from the optical time domain analyzer.

New Component Libraries

Bidirectional Optical Fibers: A new discretization parameter for broadband sampled signals offers improved performance, accuracy, and convergence for doped amplifier gain and Brillouin calculations.

Wideband Traveling Wave SOA: Flexible selection between a static or dynamic model.

AWG NxN Bidirectional: A sophisticated new AWG model facilitates the design of AWG based PON using the unique bidirectional capabilities of OptiSystem.

Optical Sources: VCSEL Laser and Laser Rate Equations: A new adaptive step engine allows for fast convergence of high frequency analog signals.

CATV Carrier Generators: New parameters include the ability to enable or disable specific channels, facilitating the measurements of carrier to noise ratio (CNR).

Carrier Generator Measured: A new list of pre-defined set of standard carrier spacing allows for easy setting up of PAL GB (up to 97 channels), NTSC (up to 157 channels) and L (up to 58 channels) systems.

Microwave components

180 and 90 Degree Hybrid Couplers, DC blockers, power splitters and combiners: A new component library geared for ROF applications. Applications include mixers, power combiners, dividers, modulators, and phased array radar antenna systems. Control amplitude and phase balance of different components.

Measured components: Bidirectional S-parameters components allow users to load s1p, s2p, s3p and s4p file formats, including s2p with noise figure data.


Polarization Delay and Phase Shift components: New components which control the delay and phase shift for each polarization. Control the delay calculation, by using linear or discrete delay.

Periodic Optical Filter: A new multi-band optical filter with user defined transmission function.


MLSE (maximum likelihood sequence estimate) Electronic Equalizer: Introducing an advanced component feature using the Viterbi algorithm to equalize the input signal through a dispersive channel.

Free Space Optics

OWC (Optical Wireless Communication) Channel: A subsystem of two telescopes and the optical wireless channel between them facilitating the simulation of intersatellite communication links. FSO is a telecommunication technology that uses light propagating in free space to transmit data between two points. The technology is useful where the physical connection of the transmit and receive locations is difficult, for example in cities where the laying of fiber optic cables is expensive.
