DGD-1000 First Order PMD Source/Emulator
Brand：DGD-1000

PRODUCT INTRODUCTION
DGD-1000
First Order PMD
Source/Emulator
The DGD-1000 is a first order polarization mode dispersion (PMD)
source that generates precise amounts of differential group delay (DGD) of up
to 400 ps, with no second order PMD.
MAIN SPECIFICATIONS
PRODUCT DESCRIPTION
Polarization mode dispersion (PMD) can seriously degrade
the quality of high-speed fiber-optic data transmission. High-speed
transceivers must meet stringent standards for PMD tolerance. The DGD-1000
accurately and repeatably generates both high and low values of differential
group delay (DGD) or first-order PMD. Both the DGD and PDL are very stable over
time and wavelength within the performance band. The instrument is available in
different versions to accommodate the need for different wavelengths and DGD
ranges.
PRODUCT SOLUTIONS
The DGD-1000 is designed to generate
accurate values of DGD over a large range for PMD tolerance testing of coherent
detection systems.
