Where is OptSim used?

Uses of OptSim

Uses of OptSim• Used to design Optical Communication Systems

and simulate them to determine their performance given various component parameters.

• To understand the working of Fiber Optic Communication Systems and its applications.

• To simulate Fiber Optic communications over a very wide area in order to calculate costs, efficiency and success rate, etc.

What can be accomplished using OptSim?

OptSim Case Studies

Er-Yb-Based Master-Oscillator Power Amplifier • This example demonstrates a master-oscillator

power amplifier using an EDFA and an Er-Yb (Erbium- Ytterbium-) co-doped fiber amplifier (EYCDFA).

MOPA output power versus pump powerSource Wavelength=1550nm

DWDM Ring with OADM (Optical Add-Drop Multiplexer) Nodes• The DWDM ring consists of six nodes and six fiber spans.

Total number of wavelengths used is eight, with 3 head-end nodes adding/dropping five channels and 3 serial OADM nodes adding/dropping two channels.

Real-time Optical Performance Analysis

Interferometric Fiber-Optic Gyroscope (I-FOG)• The interferometric fiber-optic gyroscope (I-FOG)

is today an important option for many civilian and military applications such as:• Inertial navigation and guidance systems for automotive,

aircraft, and space industries.• Satellite antennas pointing and tracking.• Mining and tunneling operations.• Helicopter altitude control.

• It brings the advantages of solid-state technology (guided-wave optics and low- voltage low-power electronics) with a cost reduction that enlarges its domain of application.

Interferometric Fiber-Optic Gyroscope (I-FOG)• The optical source is represented by an SLD centered at

1531 nm.• The multifunction integrated optical circuit (MIOC) includes

two phase-modulators in a push-pull configuration.

I-FOG OutputThe same received signal can be used to feed the feedback section for both analog and digital signal processor -based closed-loop detection schemes

Interferometric Fiber-Optic Gyroscope (I-FOG)• OptSim's advanced optical components and

analysis tools enable the user to design and simulate next generation I-FOG.

• The various optical sources and rare-earth doped fiber components can model broadband and SLD sources.

• The comprehensive fiber model takes into account the signal propagation and polarization effects.

• The Monte Carlo analysis capabilities enable the user to study phase and polarization non-reciprocity effects.
