  • Fourier Transform Optical Spectrum Analyzer, 350 - 1100 nm

    OSA201C - Thorlabs, Inc.

    Thorlabs' Optical Spectrum Analyzers (OSAs) perform highly accurate spectral measurements. Compatible with fiber-coupled and free-space light sources, these compact benchtop instruments suit a wide variety of applications, such as analyzing the spectrum of a telecom signal, resolving the Fabry-Perot modes of a gain chip, and identifying gas absorption lines. Many commonly available OSAs use grating-based monochromators, which have slow acquisition times due to the need to mechanically scan the grating and average out noise at each wavelength. Thorlabs' OSAs acquire the spectrum via a Fourier transform using a scanning Michelson interferometer in a push/pull configuration. This approach dramatically improves the acquisition time, enables a high-precision wavelength meter mode with 7 significant figures and ±1 part-per-million accuracy, and allows the included software to provide robust statistical analysis of the acquired spectra, as explained in the Design tab.

  • Gas Filter Correlation CO Analyzer

    Model T300 - Teledyne Advanced Pollution Instrumentation

    DescriptionFeaturesSpecificationsApplicationsDownloadsMaintenanceThe Model T300 measures low ranges of carbon monoxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high energy IR light source is alternately passed through a CO filled chamber and a chamber with no CO present. The light path then travels through the sample cell, which has a folded path of 14 meters. The energy loss through the sample cell is compared with the span reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing extreme sensitivity.

  • OTDR

    AQ1000 - Yokogawa Meters & Instruments Corporation

    Yokogawa Meters & Instruments Corporation will add an entry-level model, the AQ1000, to its range of OTDR (Optical Time-Domain Reflectometer) test instruments. The new model will be launched for sale outside Japan on April 13th. The new instrument complements the company’s mid-range AQ1200 Series and the high-end AQ7280 Series, and is specifically designed to increase the productivity of field personnel working on the installation and deployment of optical access networks such as Fiber To The Home (FTTH): the so-called “last mile” to consumers’ premises. The worldwide use of these optical access networks is increasing dramatically as the FTTH network structure is more and more adopted by the telecom operators, and optical fibers replace the copper cables in each household. Consequently, more and more installers will be working on fiber-optic deployment over the last mile. These installers will not need high-end OTDRs capable of measuring over hundreds of kilometers in the core network. Instead, they will need affordable OTDRs equipped with all the features which can make their job easier and faster: instruments like the Yokogawa AQ1000.

  • Polarization Controller

    8169A - Keysight Technologies

    The 8169A Polarization Controller, with single-mode fiber input and output, is used to change light from any polarized or unpolarized light source into any well-defined state of polarization. The design based on bulk-optic zero-order waveplates and a high-performance linear polarizer at the input provides optimum determination and repeatability of polarization states over a wide wavelength range. The 8169A is especially well suited for use together with a tunable laser to make swept-wavelength measurements of the polarization dependence of fiberoptic devices, by setting a set of relatively orthogonal polarization states for Mueller Matrix analysis. These measurements are supported by a Plug&Play driver and coordinated operation of the 8169A with a Keysight tunable laser and power meters can be enhanced with the Photonic Foundations Library software package. The fundamental basis of this flexible instrument also supports many general applications requiring polarization control and analysis.

  • OTDRs and Fault Locator

    AFL

    AFL optical time domain reflectometers (OTDRs) and fault locators are used to certify new fiber installations and locate faults in deployed fiber optic networks. OTDRs and fault locators are available for both multimode and single-mode networks, including FTTx PONs. OTDRs scan fiber optic networks from one end of the fiber, displaying a trace and reporting detected events such as splices, connectors, micro- or macro-bends and fiber end. Fiber length is reported along with location, loss and reflectance of detected events. Several OTDRs are available with an integrated visual fault locator (VFL), optical light source (OLS), and/or optical power meter (OPM). OTDR results can be saved and uploaded to PC for further analysis and/or archiving.
