Yenista Optical Test Equipment Repair and Calibration Services

Simbol Test Systems provides professional in-lab repair, calibration, and troubleshooting services for Yenista optical and photonics test equipment, including tunable laser sources, optical spectrum analyzers, and fiber optic measurement systems.

Yenista Optics S.A., founded in 2003 in France, developed a range of fiber optic test and measurement instruments for telecommunications and photonics applications. The company is particularly known for products such as Tunics tunable laser sources (TLS), optical spectrum analyzers, tunable filters, and multi-function test platforms. Yenista was later acquired by EXFO in 2017.

Photonetics and Tunics Platform Expertise

Many Yenista products are based on earlier designs from Photonetics, and were later rebranded across multiple platforms including EXFO, Anritsu, and NetTest. Simbol Test Systems has extensive experience supporting these legacy platforms, particularly the widely used Tunics tunable laser source series.

This cross-platform expertise allows us to service a broad range of instruments sharing similar optical and electronic architectures.

Supported Yenista Equipment

• Tunics Tunable Laser Sources (TLS)
• Optical Spectrum Analyzers (OSA)
• Tunable filters and optical components
• Fiber optic test and measurement systems
• Multi-function photonics test platforms

Service Capabilities

• Calibration using traceable optical standards
• Wavelength accuracy and stability verification
• Troubleshooting of drift and performance issues
• Repair of optical and electronic subsystems
• Functional testing and diagnostic evaluation

If your Yenista equipment exhibits wavelength drift, instability, communication faults, or general performance issues, our technicians can evaluate the condition and provide detailed service recommendations along with a repair quotation.

Service Scope

Due to the shared heritage between Yenista and Photonetics platforms, Simbol Test Systems can often support multiple equivalent or rebranded systems. This includes instruments branded under EXFO, Anritsu, NetTest, and Photonetics that share similar designs.

We encourage customers to provide model details and a description of the issue so we can determine the most appropriate service approach.

Traceable Calibration

All calibration services are performed in a controlled laboratory environment using documented procedures and precision instrumentation. Traceability is maintained to N.I.S.T. or C.N.R.C. standards where applicable.

Maintain Precision in Optical Testing

Regular calibration and timely repair help ensure accurate wavelength control and reliable optical performance. Simbol Test Systems supports customers across telecommunications, aerospace, photonics, and research industries.
