Transmitters & Receivers
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..

System integration
Integration and compatibility
Use these checks to connect DFB Butterfly Fiber Optic Transmitter 3GHz to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Fiber Type: SM28, PM1550, Special · Fiber Buffer: 0.9mm Tube, Special
- Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
- Wavelength and loss budget
- Wavelength: 1550.32
- Check the Transmitters & Receivers passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
