“Within a thousand years, I cannot find a new system to replace optical fiber. When I say this, you should not believe me, because I didn’t believe in experts.”

Father of Fiber Optics & 2009 Nobel Physics Prize Winner, Charles Kuen Kao

Optical Networking

Rafael Micro provides Trans-Impedance Amplifiers (TIA) and Laser Drivers for various optical communication markets. Light transmission is inherently high-speed and secure from eavesdropping. CMOS-based design delivers very low power consumption with excellent sensitivity and energy efficiency providing optimum solutions for data center, 5G telecom, FTTH/PON, smart home and consumer applications.

Data Center

Rafael Micro’s CMOS technology transceivers enable power-efficient  25G/100G active optic cable (AOC) design. A unique passive architecture improves equalizer flatness. High accuracy CDR design utilizing a frequency convolution architecture achieves high accuracy in eye pattern recognition. Built in pre-distortion improves driver efficiency.

FTTH/PON

Rafael Micro delivers 10G PON TIA and combo laser drivers. A passive optical network (PON) is an optoelectronic telecommunications technology delivering broadband network access to end-customers. Its architecture implements point-to-multipoint topology in which a single optical fiber serves multiple endpoints using unpowered (passive) fiber optic splitters to divide the fiber bandwidth among multiple access points.

Satellite RF Over Fiber TIA

The RT113 TIA and RT113M ROSA module is a high-quality device for RF-over-Fiber satellite signal distribution equipment. RT113M consists of a photodiode and a TIA integrated into a TO-can mounted in a FC fiber connector grounded metal housing. Having the TIA co-located with the photodiode provides an absolute minimum noise floor exactly at the point of RF reception for maximized C/N ratio of the ensuing RF signal path. Wide dynamic range with automatic gain control provides exceptional MER performance in real-world installations.
