Increasing the VCSEL wavelength from 850 to 1060 nm reduces chromatic dispersion
of fibers by approximately two thirds," says Dr.
In addition, the test demonstrated that the system could compensate automatically when adding chromatic dispersion
and polarization mode dispersion to actual transmission circuits, which could happen over a variety of networks.
Concerning chromatic dispersion
, NIST has developed two systems to measure relative group delay which broadens pulses and limits the system data rate.
The module is equipped with an advanced Digital Signal Processing (DSP) unit that eliminates the need for optical compensation in chromatic dispersion
, and features the lowest power consumption in the optical market today.
Optical Modulation Analysis software is provided for post-processing of the acquired data to perform clock recovery, correct for the effects of chromatic dispersion
, apply receiver equalization, and display a variety of eye and constellation diagrams and measurement parameters.
The N4391A offers measurement and compensation of the link's in-channel chromatic dispersion
and first-order polarization mode dispersion by analyzing the received signals, granting engineers deep insight into the root cause of constellation distortions beyond 32 Gbaud.

The company has Russia's leading fiber optic communications testing laboratory, which is equipped with more than 100 devices for complex measurements during commissioning and start-up of DWDM systems, for the analysis of optical line parameters like chromatic dispersion
, polarization mode dispersion (PMD), for transmission quality testing, GbE measuring and many others.
With its high-performance MLSE DSP engine, the MP1100Q is able to mitigate the chromatic dispersion
found in the deployed metro transport networks.
