Fiber network testing

The method and a general approach with TeleSol Group are that we would make sure even before testing, we have taken the necessary steps to make the test succeed on the first go. During the build of a fiber-optic network, we ensure any connection is scoped and cleaned (if necessary) even before the links are created. Entire networks (ISP and OSP) are being scoped. The OSP is tested through a CD/PMD test. That will show you the state of  our OSP. DWDM systems are being scoped and cleaned (if necessary). That way, we reduce faults in complex networks even before testing.

The OTDR measures distance and loss between the two markers. This can be used for measuring the loss of a length of the fiber, where the OTDR will calculate the attenuation coefficient of the fiber or the loss of a connector or splice. We make sure that the reflection and attenuation stay within acceptable parameters.

That is the first wave of testing and preparation. Once all connections are made, and the light changes the name of the dark fiber, we step to another group of testing and analysis.

AN OPTICAL SPECTRUM ANALYSER (OR OSA) is a precision instrument designed to measure and display an optical source’s power distribution over a specified wavelength span. An optical analyzer spectrum trace shows power on the vertical scale and the wavelength on the horizontal scale. It is used to determine the power alignment of all waves.

ETHERBERT OR ETHERNET BIT ERROR RATE TEST is a testing method for telecommunication circuits that uses predetermined stress patterns consisting of a sequence of logical ones and zeros generated by a test pattern generator. ALBERT typically consists of a test pattern generator and a receiver that can be set to the same pattern.

RFC 2544 IS THE INDUSTRY-STANDARD SERVICE ACTIVATION TEST for single-service Ethernet and IP (i.e. “pipe test”). The test measures  critical performance indicators and bandwidth profiles such as throughput, latency, packet Jitter, frame loss, and committed burst size (CBS). We would offer it on all bandwidth.

ITU-T Y. 1564 IS AN ETHERNET SERVICE ACTIVATION TEST METHODOLOGY, the new ITU-T standard for turning up, installing, and troubleshooting Ethernet-based services. The only standard test methodology allows for complete validation of Ethernet service-level agreements (SLAs) in a single test.
