LM-BPSK-R
Lightwave Modulator for Binary Phase Shift Key, up to 40 Gb/s The Optilab LM-BPSK-R is a high performance Binary Phase Shift Key (BPSK) lightwave transmitter designed for Optical Communication up to 40 Gb/s or beyond. The LM-BPSK-R incorporates an internal laser source (DFB, tunable laser) which couples into a high low drive speed MZI modulator for BPSK/ DPSK modulation, with a broadband modulator driver. The LM-BPSK-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.
