Intern, Digital Twin of DWDM Transport Optical Networking

Coherent Corp. • Santa Clara, CA

31d • Onsite

About The Position

Develop and implement digital twin models of DWDM optical transport systems, including fiber propagation, optical amplification, ROADMs, and coherent
transponders.
• Build simulation frameworks to model physical-layer impairments, including
OSNR degradation, nonlinear effects, dispersion, and channel interactions.
• Investigate advanced modeling approaches for network performance prediction
and optimization using system-level simulation and data-driven techniques.
• Analyze large-scale network scenarios to evaluate capacity, reach, and
reliability under varying system configurations.
• Collaborate with optical system architects and research engineers to refine
modeling methodologies and validate results against experimental or system data.
• Document research methodology, modeling framework, and results.
• Deliver a final technical report and presentation summarizing the digital twin
architecture, simulation results, and research insights.

At Coherent, interns are valued members of our team and have the opportunity
to contribute to cutting-edge research and technology development. Interns in
the CTO organization work closely with leading experts in optical
communications and photonics to explore innovative ideas that may shape
future products and systems. In addition to hands-on project experience, the
internship program includes opportunities to connect with fellow interns and
colleagues across the organization through networking events, team-building
activities, and technical seminars.
