Transmitters & Receivers
The EMTX is a 12 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.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
12 GHz Plug-Play Electro-Absorption Modulated Fiber Optical Transmitter: Laboratory optical integration depends on preserving the optical budget through the complete path. The 1550nm wavelength specification sets source and detector compatibility. The fiber/interface entry (SM28) must match the connected components.

Technical FAQ
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: 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.
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.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
