Transmitters & Receivers
35 GHz Plug-Play Electro-Absorption Modulated Fiber Optical Transmitter
The EMTX is a 35 GHz fiber optic transmitter designed for RF-over-fiber, antenna remoting, and broadband digital communication, offering high-fidelity RF-to-optical signal conversion. It features a monolithically integrated distributed feedback (DFB) laser coupled with a high-speed electro-absorption modulator (EAM) for efficiently converting both analog and digital RF signals into optical signals with high fidelity. The module contains a precision laser and a TEC controller, with a built-in DC bias circuit to ensure a linear response. The EMTX operates on a low-noise ±5V DC power supply, available as an optional accessory. The bias T voltage is adjustable via USB to optimize performance.

System integration
Integration and compatibility
Use these checks to connect 35 GHz Plug-Play Electro-Absorption Modulated Fiber Optical Transmitter 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 · Connector: FC/APC
- 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: 1550nm
- 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.
- Control interface
- DC Power Supply: Non, DPPS5V
- Match supply voltage, analog or digital command range, connector pinout and default optical state to the instrument interlock. Confirm the unpowered state explicitly — it decides what happens to the link on a power failure.
Technical FAQ
