Increased transmission speed of 10 Gbps or more is limited by dispersion phenomenon, specifically, polarization mode dispersion (PMD) and chromatic dispersion (CD). These parameters must be considered when deploying or upgrading to 10 GigE capabilities.

Fiber’s increased penetration in next-generation networks coupled with its negative potential when contaminated makes systematic proactive inspection essential to next-generation network performance, and it makes the current practice of using only an OPM when testing fiber obsolete. Adoption of a fiber handling best practice will eliminate the installation of contaminated fibers and optimize the performance of next-generation networks.

The JDSU Reference Guide to Fiber Optic Testing is written for fiber optic installers, project managers, telecom technicians, and engineers who need to understand, apply, and correctly measure and record the performance of fiber infrastructures.
This first volume reviews the basics in systems, standards, and network architectures and focuses on how to make the most of Optical Time Domain Reflectometers (OTDRs) to install, turn-up, and maintain fiber optic networks. The book covers:
Basic system and fiber infrastructure design
Basic fiber infrastructure testing
Basic OTDR testing
Advanced OTDR testing

While network-centric turn-up testing verifies the L2/L3 components of
the carrier SLA, it does not guarantee customer satisfaction. To further
ensure that the customer applications perform satisfactorily, service
providers must also conduct application-centric turn-up testing to
qualify their networks.

Video service quality of experience (QoE) is a perceptual environment
whose components are difficult, or near impossible, to directly measure
in a practical operational manner. Yet, service providers can make
objective measurements of a set of parameters, or quality of service
(QoS) metrics, which can be used to evaluate the performance of the
network and its delivery of an acceptable QoE. A model for mapping these
key parameters to important QoE indicators provides the basis for a good
overall end-to-end video quality assurance program.

Installing and upgrading CWDM equipments in the field requires several steps to guarantee that systems are set up correctly and are working error free when brought into service. Field testing serves as an important component in the turn-up and upgrade process and must be conducted at several stages during the process.

Function and Measurement Tasks - Fiber-to-the home (FTTH) promises unlimited bandwidth, however, new and economically viable concepts must be developed and delivered to the customer. As demand for bandwidth increases, WDM-PON will make gradual expansion possible.

Testing the fiber physical characteristics is necessary to determine the magnitude of loss in the water peak area, which is the most significantly changing parameter. Several methods or test solutions can perform this measurement in the field, even after the fiber plant has been installed.
