Lab and production measurement technology

The PDL multimeter PolaChex simultaneously measures the Polarization Dependent Loss (PDL), Insertion Loss (IL), and optical power of a device under test (DUT) in just 30 ms.

The ERM-202 is a dual channel polarization extinction ratio (PER) meter specifically designed to simultaneously measure the PER and power ratio of a device with two polarization maintaining (PM) outputs, such as a Y-branch fiber gyro IOC, PM coupler (PMC), or polarization beam splitter (PBS), as well as evaluate the performance (output DOP) of depolarizers.

The OCA-1000 is a multi-channel optical component analyzer capable of performing simultaneous insertion loss (IL), polarization dependent loss (PDL), and optical power (P) measurements on multiple optical paths.

The DOP-201 measures and displays the Degree of Polarization (DOP) of a light source in real time with high accuracy and wide dynamic range.

GPCs' 4-axis Polarization Scrambler Module uses a breakthrough all-fiber technology to effectively randomize polarization states. Depolarizing by polarization scrambling has many important applications:

GPCs' high-speed polarization state generator (PSG) module provides the ability to generate 6 states of polarization (-45°, 0°, 45°, 90°, RHC & LHC) across the Poincaré Sphere in less than 250 ?s, with an impressive repeatability of less than 0.1 degrees.

This module integrates a General Photonics all-fiber dynamic polarization controller with miniature piezo driver card, so that the SOP of the signal can be directly controlled either by a 0-5V analog control signal or a 12-bit TTL digital control signal. Because there is an on-board HV DC/DC converter, no external high voltage power supply is required.

The PolaRITE III is a low profile polarization controller for system integration with significantly reduced height and size.

The FPS-003 all fiber phase shifter/modulator combines a wide modulation bandwidth (up to 60 kHz) with low half-wave voltages to create a long-range device that can be driven by standard function generators.

InsideView(TM) is an optical coherence domain reflectometer (OCDR- 1000) designed to obtain space-resolved reflection information inside a fiber optical component, such as a Photonic Integrated Circuit (PIC), for diagnosing quality or design issues.

OCT- und Sensorsysteme erfordern hochleistungsfähige ausgewogenePhotodetektoren, um das Signal-Rausch-Verhältnis des Systems zu verbessern. Die BPD-003 wurde speziell für OEM-Anwendungen in solchen Bereichen entwickelt, die auf niedrige Kosten und geringe Größe sowie hohe Leistung ausgelegt sind.

PMD and PDL are important considerations in many applications, especially high data-rate communications. With the development of high precision test equipment and tighter-tolerance systems, a need has arisen for extremely precise calibration standards.
