Fiber Characterization (CD/PMD)
Fiber characterization" is performing a comprehensive suite of tests that determine all of the key performance attributes of installed fiber infrastructure. A comprehensive suite of measurements that is carried out on a fiber optic cable link to determine the key performance attributes of that link which may affect current or future applications that operate over that link. Fiber characterization also allows the quality of the fiber optic cable link to be assessed, including the identification of the type and grade of fiber installed." Full fiber characterization includes:
- Connector end face inspection
- Insertion loss measurements
- Return loss measurements
- OTDR testing
- Chromatic dispersion testing
- Polarization mode dispersion testing
- Spectral attenuation
Results and analysis
The results of the characterization need to be documented and an important and valuable part of the process is the analysis and interpretation of the results.
This analysis will include an assessment of the infrastructure quality and its ability to support particular systems.
Jitter & Wander Testing/Analysis
Jitter and Wander provides the most comprehensive, easy-to-use measurements for both SDH and PDH equipment and networks. With its wide-ranging and comprehensive generation, analysis, pointer movement, automated jitter output, transfer, and tolerance testing, it is the complete solution for your current and future test requirements. Now you can fully test and qualify the timing and synchronization of your new PDH/SDH equipment and networks. Jitter history histograms can be correlated with simultaneously-acquired Wander TIE data so troublesome conditions can be quickly diagnosed.
IP Load Testing
IP Load testing helps ensure your web applications and web sites can handle the load conditions that it will face in production. It helps ensure that critical information and services are available at speeds your end-users expect.
It provides flexible user scenarios and realistic load types to help application load test. The load tests can help simulate real time user activities and load test hundreds or even thousands of concurrent users under dynamic load conditions.
