25GHz Lithium Niobate Waveguide Fiber Optical Intensity Modulator

SKU: LNML

The Fujitsu FTM7920FB/301 is a Lithium Niobate Mach–Zehnder optical intensity modulator that uses a push-pull, traveling-wave electrode structure to provide high-speed, low-drive-voltage modulation in the C-band, and it incorporates an internal bias control section with a micro-heater and built-in optical power monitor photodiode for precise bias point adjustment and long-term stability; an optional automatic bias control (ABC) version is available in which the device is mounted on a PCB and delivered fully tested with a slow-feedback stabilization circuit to eliminate DC drift, and compatible single-stage 17 dB (5 V) or dual-stage 40 dB (8 V) RF driver amplifiers can be used to achieve the required modulation voltage for >20GHz for telecom-grade performance.
The device is based on traveling push-pull waveguide electrode design. We offer mounting the device on an automatic bias control PCB option for convenient application.
