Abstract: Presented herein are a submount architecture for an electro-optical engine, which may be embodied as an apparatus in the form of at least an electro-optical engine and a multimode node, and a method for providing the same. According to at least one example, an apparatus includes a printed circuit board (PCB), a substrate with a finer structuring than the PCB, and electro-optical components. A bottom surface of the substrate is coupled to the PCB and electro-optical components are mounted on or in a top surface of the substrate. The electro-optical components include one or more optical components arranged to emit optical signals towards and/or receive optical signals from an area above the top surface of the substrate.

Abstract: At a controller of an optical module including optical transmitters and optical receivers coupled to the controller and coupled to first and second optical fibers: responsive to a first command, first configuring the optical module to operate in a normal mode in which the optical module operates at a maximum communication capacity by transmitting and receiving a maximum number of wavelengths, that the optical module is capable of transmitting and receiving, on each of the first optical fiber and the second optical fiber; and responsive to a second command, second configuring the optical module to operate in a backward compatible legacy mode in which the optical module operates at a reduced communication capacity compatible with a legacy optical module by transmitting and receiving a reduced number of wavelengths, that is less than the maximum number of wavelengths, on each of the first optical fiber and the second optical fiber.
