Lightwave Transmitter for QPSK/QAM
The Optilab LT-QPSK-R is a high-performance Quadrature Phase Shift Key (QPSK) lightwave transmitter designed for optical communication up to 80 Gb/s or beyond using polarization maintaining (PM) optical fiber. The incorporated internal PM laser source couples into a dual IQ drive speed MZI modulator for QPSK modulation, with dual broadband modulator drivers which provide high-quality, single-ended voltages to drive the QPSK LiNbO3 modulator, with independent control and monitoring on both amplified signals. Adjustable RF gain and eye crossing through the front panel interface and LabVIEW software can be performed. The LT-QPSK-R has a built-in Automatic Bias Controller (ABC) which allows for stable long-term operation. The LT-QPSK-R can also be used for Quadrature Amplitude Modulation (QAM). Contact Optilab for more information.
