DP and SP QPSK Modulator Bias Controllers
Description
DP and SP QPSK Modulator Bias Controllers are compact and powerful devices designed to precisely control the bias positions for QPSK modulators used in 100Gbit QPSK or QAM applications. These controllers enable optimal performance and improved optical transmission properties, such as total reach, dispersion tolerance, and spectral efficiency.
Developed specifically for QPSK modulators, the OZ Optics QPSK Modulator Bias Controllers are feature-rich and offer advanced control capabilities.
