Space Amplifiers

One of MPBC's Space-Based Optical Amplifiers

We provide qualified PM and Non-PM Boosters and PreAmplifiers for LEO, MEO, and GEO, where high reliability, low mass and low power consumption are essential. Our customized “New Space” designs use COTS optical components, which have undergone rigorous testing to ensure survivability under vacuum and radiation conditions. Optional radiation tolerant control electronics are available for simplified operation. Our custom mechanical housings are designed around your footprint and mission specific shock and vibration requirements, with additional radiation shielding for missions up to 100 krad.  

With our space qualified building blocks, we can move rapidly from custom EM designs, to successful QM qualification, to full FM serial production.  All quality control processes are in place, making the transition from prototype to serial production ramp up seamless. R&D and manufacturing are conducted in our North American facility.

With over 30 years of experience in providing optical amplifiers for sensing, test systems, submarine and terrestrial communications, we are now launching into space.
