DFB Butterfly Fiber Optic Transmitter 3GHz

The FOTR Series Fiber-Optic Transmitters convert high-speed electrical signals into laser output with excellent analog linearity, wide bandwidth, and high dynamic range. Designed for reliability, they feature a hermetically sealed 14-pin butterfly package with a thermo-electric cooler for wavelength stability, an internal power monitor with feedback control for constant output power, and an optical isolator to protect against reflection spikes. Built with a GaAs quantum well structure and grating aligned to ITU grids, they support multi-channel transmission through a single fiber. Each unit undergoes rigorous testing to ensure performance. The FOTR is available in all-in-one benchtop configurations, modules, or driver kits, with feedback control drivers and externally cooled mounting fixtures for precise wavelength stabilization..
