Introduction

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.

Introduction

The MPC-203 is a High Speed Multifunction Polarization Controller specially designed to meet the high SOP scrambling requirements needed for stress testing coherent receiver’s polarization tracking performance.

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 variable high speed polarization scrambling up to 400,000 revolutions/s.

Unlike other high speed polarization scramblers found in the market, this all-fiber, pass-through fiber design comes with the lowest IL, PDL, PMD and activation loss

Introduction

High speed fiber optic transceivers, including those deploying coherent detection technology for 40Gb/s and 100Gb/s data transmission, must meet stringent PDL tolerance specifications. In addition, the PDL tracking speed and response time of the PDL mitigation algorithm of a coherent detection receiver must be quantified.

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.   

Introduction

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.

The PMD-1000 uses high speed ternary magneto optic crystals to generate PMD. The PMD switching time is as little as one millisecond, making the PMD-1000 the fastest PMD generator on the market.
