Introduction

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.

The generated SOP and the corresponding Poincaré representation are displayed on a PC via USB interface.

Output SOP can be defined by Stokes parameters, by manually tuning the SOP to any point on the Poincaré sphere or by optimizing a polarization-dependent metric. Once a desired output SOP is found, the instrument maintains the SOP against input SOP fluctuations.

Introduction

The POS-202, POS-203 and POS-204 polarization stabilizers maintain stable output states of polarization (SOP) against rapid input SOP fluctuations, compensating for an input polarization discontinuity in as fast as 5 ms, or tracking without resets against a continuous input SOP rotation of up to 32p/s.

The POS-20X architecture includes a polarization controller, in-line polarization monitor, and proprietary algorithms.

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.

Introduction

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.

Introduction

The MPC-201 is an all fiber polarization controller packaged in a full featured instrument with multiple modes of local or remote operation.

Variable Rate Scrambling Mode

• Tornado Pattern: uniform SOP variation for system stress testing
• Rayleigh distribution of SOP for fiber link simulation
• Triangle scrambling for PDL measurement
• Discrete random scrambling for coverage of Poincare sphere

SOP Modulation Mode

• Each polarization control axis is controlled with a sine, square, or triangle wave of defined frequency and amplitude.

Manual Polarization Mode

• Each polarization control axis is controlled by setting the input voltage from the front panel controls or through a remote control interface.

Triggered Scrambling Mode

• Discrete, random SOPs are generated in response to a trigger input.

11896A Emulation Mode

• Control compatibility with the discontinued Agilent 11896A.
