Problems solved by technology

Both three-line and two-line reference procedures can be employed with fiber-pigtailed detectors, but they are known to introduce small biases in insertion loss measurements (see ANSI / TIA-526-14-B-2010B.5 and C.5)
However, because OLTS power detectors are fiber-pigtailed, the one-line referencing procedure is not applicable and the two- and / or three-line referencing procedures suffer from the small deviations described above

Embodiment Construction

[0026] The methods and systems described herein can be used to characterize fiber optic links or other optical devices, to reference OPLM systems, and to determine insertion loss values ​​for DUTs using the referenced OPLM systems.

[0027] An OPLM system may be provided in the form of two OPLM devices optically coupled to each other by a test link comprising a DUT. For example, these OPLM devices may be provided in the form of an OLTS or in the form of two multifunction loss testers. Components and configurations of OPLM devices and systems will be described below, however, it should be understood that these OPLM devices of the OPLM system can be configured to measure multiple global values ​​of the DUT, including: bidirectional loss of the DUT, bidirectional optical return loss (ORL) and length. These bi-directional measurements are allowed if each of these OPLM devices has a pigtailed light source and a fiber pigtailed detector. These pigtailed assemblies are optically co...

Abstract

Computer readable memory recorded on it is used to use instruction code performed by a computing device to measure with a optical power loss measurement (OPLM) system.This instruction code usually includes: a code for displaying a first instruction set, which includes a first power value of the test light from a first reference to the output of the Optical Wave Guide; it is used to display a second instruction set.The code of this second instruction includes a second power value of the test light from a reference waveguide link output.It is used to display a third instruction set. The third instruction set includes a reference power value that measures the OPLM system.The reference power value and based on the first and second power values determine a coding of a corrected reference power value.

Description

[0001] References to related applications [0002] This application claims priority to US Provisional Application Serial No. 62 / 089581, filed December 9, 2014, the contents of which are incorporated herein by reference. technical field [0003] The improvements relate generally to the field of measuring insertion loss values ​​of devices under test (DUTs), and more specifically to the use of two optical power loss measurement (OPLM) devices, such as optical loss test sets (OLTS), to measure insertion loss values. field. Background technique [0004] Optical power loss measurements are critical to properly manage network communication systems. To this end, the Telecommunications Industry Association (TIA) and the American National Standards Institute (ANSI) established standard procedures for measuring power loss values ​​using a light source and a power meter, known as the Light Source Power Meter (LSPM) method. The ANSI / TIA-526-14-B-2010 standard proposes different method...
