Generic Requirements for Hand-Held Stabilized Light Sources, Optical Power Meters, Reflectance Meters, and Optical Loss Test Sets
Document Number GR-198
Issue Number 02
Issue Date Dec 2011
Replaces TA-NWT-000198 Issue04
ABSTRACT: This document presents the Telcordia view of proposed generic requirements and objectives for Stabilized Light Sources (SLSs), Optical
Power Meters (OPMs), Reflectance Meters, and Optical Loss Test Sets (OLTSs). Each of these test sets is part of the optical loss
testing family of test equipment. This document should be used as a reference for all three types of test sets.
This family of test sets is used to characterize (generally loss and reflectance) optical fibers in the inside and outside plant
portions of a service provider's optical network. In the Telcordia view, these requirements should be met in order to provide for
satisfactory operation in a communications service provider's environment under normal conditions.
This document includes generic functional design criteria, generic mechanical and optical requirements, desired features, and test
methods for comparing the product against the stated generic requirements. The specified test methods are intended to reflect the
service provider's operational conditions for these optical test sets.
- Covers the new generation of test sets that are smaller in size and weight and that are almost exclusively single-use battery
- Includes modifications to the performance criteria for these test sets and increased support of multiple wavelength testing
- Provides the ability to use the same test set for both the indoor and outdoor fiber plant
- Contains a listing of features, functions, and performance criteria for hand-held, portable fiber loss measurement equipment used
by fiber installation technicians in indoor and outdoor applications.
