PMD Source
PMD-1000
The PMD-1000 is a flexible, digital PMD source that deterministically generates precise 1st order PMD up to 180 ps and 2nd order PMD up to 8100 ps2. Its quasi-continuous operation mode enables independent generation of first order and wavelength independent second order PMD for uniform coverage of the PMD space.

Polarization Synthesizer/Analyzer
PSY-201
The PSY-201 generates and maintains any state of polarization (SOP), regardless of the input SOP. It combines General Photonics’ patented controller, polarimeter, and control algorithms into an instrument that functions as both an SOP generator and a polarization analyzer.

product
PDL Emulator
PDLE-101
The PDLE-101 is specially designed for such PDL-related tests. This PDL source/ emulator can generate individual PDL values between 0 dB and 20 dB, with a resolution of 0.1 dB for PDL tolerance testing. It can also generate variable PDL with user defined range, waveform, and speed for PDL tracking speed and recovery time tests. The instrument can be controlled via the front panel keypad or by remote control via USB, RS-232, GPIB, or Ethernet interfaces. The residual PMD of the unit is less than 0.1 ps.

Polarimeter
POD-201
The POD-201 is an FPGA powered polarimeter designed for high speed polarization analysis and monitoring. The instrument simultaneously measures the four Stokes parameters to yield the instantaneous state of polarization (SOP) and degree of polarization (DOP) of an input light beam. The unit is controlled with FPGAs that support sampling rates of up to 4MS/s.

Polarization Measurement System
PSGA-101
The PSGA polarization measurement system is the most accurate product on the market for analyzing PMD, PDL and other polarization related properties of light sources and optical materials. The patented design utilizes magneto-optic crystals for high accuracy and repeatability.

product
Polarization Scrambler
PCD-104
The PCD-104 Scrambler uses patented all-fiber technology to randomize polarization states. Specifications include low insertion loss and low back reflection as well as minimal phase and amplitude modulation. The instrument can be used in automatic test systems under remote control through digital interface options.

product
PDL/IL Multimeter
PDL-201
The PDL-201 uses a patented maximum and minimum search method compliant with TIA/EIA-455-198 to simultaneously measure the Polarization Dependent Loss (PDL), Insertion Loss (IL), and optical power of devices in just 30 ms. Unlike PDL meters that use the polarization scrambling method, the PDL-201's max-min technique is useful for both low and high values of PDL. And unlike instruments that use a Mueller Matrix technique, the PDL-201 has a wide wavelength range without calibration.

Distributed Polarization Crosstalk Analyzer
PXA-1000
The PXA-1000 Distributed Polarization Crosstalk (X-Talk) Analyzer is an enhanced white light interferometer that measures space-resolved stress by analyzing stress-induced polarization cross-coupling along a length of polarization maintaining (PM) fiber. The patented design eliminates strong zero-order interference and reduces the multi-coupling interference common in traditional white light interferometers, both of which can cause “ghost” peaks in the measured signal. The removal of the “ghost” peaks enables the PXA-1000 to unambiguously identify the magnitudes and locations of actual x-talk peaks, resulting in higher measurement sensitivity, higher dynamic range, and higher spatial measurement accuracy.

Degree of Polarization Meter
DOP-201
The DOP-201 measures and displays the Degree of Polarization (DOP) of a light source in real time on the front panel display. The instruments incorporates a patented maximum & minimum search technique that accurately measures both low and high DOP. This technique is superior to polarimeter-based methods that are inaccurate at low values of DOP as well as scrambler-based methods which are less accurate at high values of DOP.

product
Polarization Stabilizer, 3 Port
POS-203
The POS-203 has optical ports for signal input and output and a third port for an optical feedback signal. It automatically optimizes the output SOP to either maximize or minimize and optical or electrical feedback signal. It also allows the operator to control the step size, feedback delay, activation threshold, and search algorithm (maximum or minimum) from the front panel as well as remotely via one of the digital interfaces.

Extinction Ratio Meter
ERM-202
The ERM-202 is a single or dual channel polarization extinction ratio (PER) meter. When used with a broadband source, it directly measures PER. Single and dual channel models are available. The single channel instrument can be upgrades to two channels version at a later date. By combining low noise circuitry with a high resolution stepper, the ERM series achieves a PER dynamic range of 50 dB.

Advanced Multifunction Polarization Controller
MPC-202
The MPC-202 is an advanced Multifunction Polarization Controller specially designed to meet the requirements of coherent receiver performance tests. It combines General Photonics' award winning PolaRite™ II/III polarization controller with proprietary polarization control algorithms to achieve a wide range of polarization control functionalities, including high speed quasi-uniform rate polarization scrambling, random-rate polarization scrambling with Rayleigh rate distribution, discrete-state polarization scrambling with high slew rate, sine, square, and triangle-wave SOP modulation, and manual polarization control functions.
