Lightwave Modulator for QPSK/ QAM
The Optilab LM-DPQAM-R is a high performance Dual Polarization Quadrature Amplitude Modulation (DP-QAM) lightwave transmitter designed for Optical Communication up to 400 Gb/s or beyond. The LMDPQAM-R incorporates an internal laser source (DFB, tunable laser) which couples into a four IQ drive speed MZI modulator for DPQAM modulation, with four broadband modulator drivers. The LM-DPQAM-R can also be used for Quadrature Amplitude Modulation (QAM). The LM-DPQAM-R has a built-in Automatic Bias Control board which allows for stable long-term operation, with up to 4 bias operating modes. Adjustable RF gain through the front panel interface and LabVIEW software can be performed. Contact Optilab for more information.
