Small-sized welding packaging high power simulation optical module

Abstract

The invention discloses a small-sized welding packaging high power simulation optical module. A simulation laser source inner core, the superfluous external circuit of which is stripped, is disposed in a TO case in a packaged manner, and an optical detector is disposed in another TO case, and the simulation laser and the optical detector are respectively connected with an input optical interface and an output optical interface. A functional circuit comprises a driving circuit and a pre-amplification and limiting-amplification circuit. A transmitting and receiving optoelectronic device, the functional circuit, and the optical interfaces are disposed on the same circuit board, and are disposed in an SFF2*10 for welding and packaging. Welding pins are connected with the corresponding functional pins of the optoelectronic device and the functional circuit. The simulation laser is connected with an automatic power control circuit, a pre-distortion compensation circuit, and an automatic temperature control circuit device. The simulation laser and the optical detector are connected with a digital diagnosis monitoring circuit, and the optical detector is also connected with a signal alarming circuit. The linearity, the spectral characteristic, the temperature stability performance, and the modulation characteristic of the small-sized welding packaging high power simulation optical module are better than that of a digital laser, and the small-sized welding packaging high power simulation optical module has advantages of high optical power, large dynamic range, small packaging, stable linear range, and high reliability.

Description

technical field [0001] The invention relates to the technical field of analog optical module design and manufacture, in particular to a high-power analog optical module that can be miniaturized and welded and packaged.
