PITTSBURGH, Oct. 2, 2023– Coherent, a leader in optical communications components and subsystems, announced that it would demonstrate next-generation transceiver technology for 100G, 400G, and 800G digital coherent optics (DCO) in ultracompact pluggable form factors for disaggregated systems at ECOC 2023 in Glasgow, Scotland, October 2-4, stand #406. Such advances are critical to sustaining the growth of optical communications networks driven by artificial intelligence and machine learning.

140 GBaud/800 Gbps Optical Engine: a completely calibrated and integrated coherent transmitter-receiver optical subassembly (IC-TROSA) with a fully digital control interface


  • The demonstration showcased the 800 Gbps optical link powered by Coherent's 140 GBaud IC-TROSA, coupled with Marvell's Orion DSP.

  • The 140 GBaud IC-TROSA enabled 0 dBm output power without the need for external amplification or tunable filters to achieve industry-leading performance. The IC-TROSA offered unparalleled levels of integration including narrow-line laser, IQM modulator, receiver, amplification, filtering, and electronics in a hermetically sealed digitally controlled gold box.

  • The IC-TROSA not only contained all the optical components required to support a small-form-factor pluggable (i.e., QSFP-DD and OSFP-DD) with state-of-the-art performance but also achieved it without fiber splicing and at an industry-leading power efficiency.


400ZR and 400G OpenZR+ QSFP-DD DCO transceiver as part of the OIF multi-vendor interoperability showcase

  • Coherent participated in the OIF's 400ZR/400G OpenZR+ and Common Management Interface Specification (CMIS) interoperability demonstrations.

  • Coherent showcased the 400ZR and 400G OpenZR+ QSFP-DD DCO transceivers that feature advanced indium phosphide (InP) photonic integration in a compact OIF Type-2 IC‑TROSA.

  • The CMIS demonstration highlighted Coherent's commitment to simplifying the management of these modules through an industry-standardized common and adaptable management interface.


100G QSFP28 0 dBm DCO transceiver for edge and aggregation networks

  • Coherent showed a live demonstration of the industry's first 100G QSFP28 DCO transceiver, boasting a 0 dBm output power and operating over 100 km of fiber, while still achieving the lowest power density to support legacy QSFP28 ports.

  • The transceiver featured Coherent's Steelerton® DSP, the industry’s first purpose-built DSP for 100ZR applications that enabled best-in-class power efficiency.

  • Optimized for minimal power consumption and a compact form factor, this module paired the Steelerton® DSP with a highly efficient silicon photonics optical front-end and a power-efficient internally developed tunable laser.
