40 GHz EAM Fiber Optical Transmitter

SKU: EMTX

The EMTX is a 40 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 TEC controller and includes a built-in DC bias circuit to ensure a linear response, while a USB interface enables laser power adjustment, bias control voltage adjustment, and status monitoring. The EMTX operates on a low-noise ±5V DC power supply, available as an optional accessory.
