High Performance and Volume Manufacturability with the Design Simplicity of Infinera's TROSA

Leveraging a monolithic indium phosphide photonic integrated circuit (PIC), Infinera’s monolithically integrated transmit-receive optical sub-assembly (TROSA) sets a new industry record in the high-density integration of discrete functions into a single submodule, including PIC, radio frequency application-specific integrated circuit (ASIC), and thermoelectric cooling. It provides leading optical performance with 0 dBm, low out-of-band noise for successful deployment over colorless ROADM architectures, high transmit optical signal-to-noise ratio (OSNR), and high receive sensitivity. Infinera’s TROSA is designed around software configurability, simplicity, and high-volume manufacturability for deployment in both coherent pluggables and embedded optical engines, as well as in high-volume units fueled by network edge/access growth.
