ModeSYS Product Overview

ModeSYS™ supports the design and simulation of multimode optical communication systems. With a primary focus on data communication applications, ModeSYS allows users to evaluate both temporal and spatial attributes of optical signal propagation. ModeSYS can be used as standalone tool or combined with OptSim to form a comprehensive single mode and multimode optical communication system design suite.

Modeling of Electronic Dispersion Compensation (EDC) in ModeSYS. 
ModeSYS and OptSim include FFE- and DFE-based EDC with MMSE-based optimization.

Benefits

  • Simulates both temporal waveform and spatial modes of multimode systems combining system-level speed with device-level representation accuracy.
  • Virtual prototyping of the multimode optical communication system for increased productivity and reduced time to market.
  • Fully supports yield analysis through statistical models of multimode fiber defects such as Cambridge 81 and 108 fiber models.
  • Interfaces with device-level tools such as RSoft's BeamPROP to simulate at the system level custom components designed at the device level.

Applications

ModeSYS is ideally suited for computer-aided design of multimode optical communication systems including, but not limited to:

  • Gigabit Ethernet, e.g. 1GbE, 10GbE
  • 10GBASE- systems, e.g. SX, LX-4 and LRM
  • Serial / WDM
  • TTx / PON
  • EDC
  • Optical Interconnects
  • FSO

Features

  • Multimode fiber model includes Helmholtz equation solver supporting arbitrary index profile and index profile perturbations.
  • Extensive set of measurement tools enables the user to analyze key characteristics of multimode optical communication systems, such as:
    • Transverse mode profiles
    • Effective modal bandwidth (EMB)
    • Signal over time
    • Differential Mode Delay (DMD)
    • Signal spectra
    • Encircled Flux (EF)
    • Eye diagrams
    • Radial power distributions
    • BER
  • Mode-propagation model supports modal dispersion and Differential Mode Attenuation (DMA).
  • Comprehensive spatial model using distinct transverse mode profiles supports launch-condition, optical-coupling, and alignment-tolerances analysis.
  • Mode coupling effects to model random exchange of powers between modes due to microbends and geometric irregularities in a real fiber.
  • Extensive library of predefined manufacturer components makes it easy to model commercially available devices.
  • Deterministic and statistical component parameter sweeping.
  • Powerful encryption capabilities make protecting your schematics and model parameters easier than ever.
  • Application Programming Interface (API) for programming languages such as C/C++ for the development of custom user models.
