Telecom/Sonet Fiber Optics

Your industry, our focus

Eurofins E&E North America utilizes fully automated test systems for long-term reliability testing of optical fiber components under environmental and mechanical stress conditions.

Fiber optic components require performance and reliability testing in accordance with numerous Telcordia and other standards. Eurofins E&E also has extensive lab capabilities dedicated to SONET testing.

These systems can perform in-situ monitoring of many optical parameters of over 200 channels simultaneously. In addition to testing, Eurofins E&E offers compliance consulting and test plan development.

Testing includes:

Product geometry
Cross-sectioning
Geometric tolerances
Mechanical testing (vibration, shock, etc.)
Fiber integrity (tensile loading, fiber flex and twist testing)
Environmental simulation (thermal cycling, thermal shock, life aging)
Airborne contaminants
Salt spray
Fungus resistance testing
FIT rate assessment
Digital optical component testing (BERT, eye diagram, etc.)

SONET Testing

Eurofins E&E is fully capable of testing to Fiber Optic design standards such as GR-253-CORE for SONET equipment as well as its equivalent international standards for SDH equipment.

Testing of SONET/SDH equipment involves a variety of areas, such as:

Network Compatibility and verification of Network Interface design
Verification of STS-n/STM-n frame structure, Synchronous Payload Envelope/Administrative Unit
Timing and Synchronization
Jitter and Wander Testing

Physical Parameter Testing involves:

Transmitter Characteristics, including Operating Wavelength Range, Extinction Ratio, Side-Mode Suppression Ratio, Eye Diagram Mask and Spectral Characteristics
Receiver Characteristics, including Receiver Sensitivity, Overload and Reflectance
Characteristics
Pointer Adjustment
Automatic Protection Switching (APS) Testing
Tandem Connection Monitoring (TCM)

The general list of international standards for SDH Equipment is as follows:

ITU-T G.703
ITU-T G.707
ITU-T G.783
ITU-T G.957
ITU-T G.958

There are various other standards that could apply depending on the function of the Optical Product to be tested. Countries like Brazil, Japan, Switzerland, Poland, and Singapore have their own standards for SDH-type equipment.

Eurofins E&E is able to test against these standards as well as vendor-driven requirements. Our GR-253-CORE testing capability, coupled with our existing capability to test fiber optic components to GR-326-CORE, GR-910-CORE, GR-1073-CORE, GR-1209-CORE and GR-1221-CORE allows Eurofins E&E to satisfy all testing aspects of your Optical Product.

Additionally, Eurofins E&E offers protocol analysis/system level testing to:
