Abstract
Methods and arrangements for providing compact optical paths between an optical connector, such as an MTRJ connector, and optoelectronic chips contained in TO cans. The methods and arrangements employed for creating the optical paths include the use of fibers that are not prone to fail from bending stresses, or waveguides.
Claims18
