IC-TROSA

Integrated Coherent Transmitter & Receiver Optical Sub-Assembly (IC-TROSA)

Implement coherent transmission using the (IC-TROSA) - an optical sub-assembly combining all the elements of a coherent optical front-end with the associated control circuitry.

The IC-TROSA’s miniaturized efficiency enables small form factor Digital Coherent Optics (DCO) transceivers in a QSFP-DD or OSFP format. And since this is a fully calibrated and tested assembly, it reduces costs and testing times compared to discrete components.

IC-TROSA – Some Key Details

This device is full C-band tunable and supports multiple modulation formats such as QPSK, 8QAM, and 16QAM, at symbol rates >60 GBd, enabling data transmission up to 400 Gb/s.

Applications

  • Pluggable Digital Coherent Optics (DCO) transceivers for data rates up to 400G, e.g. OIF 400ZR

  • Very high-density coherent line card designs
