Coherent to Demonstrate Next-Generation Transceiver Technology for Digital Coherent Optics in Ultracompact Pluggable Form Factors for Disaggregated Systems at ECOC 2023

The live demonstrations will include the following:

• 800G coherent optical engine based on the 140 GBaud IC-TROSA from Coherent and the Orion DSP from Marvell
• 400ZR and 400G OpenZR+ QSFP-DD DCO transceiver as part of the OIF multi-vendor interoperability showcase
• 100G QSFP28 0 dBm DCO transceiver

PITTSBURGH, Oct. 02, 2023 (GLOBE NEWSWIRE) — Coherent Corp. (NYSE: COHR), a leader in optical communications components and subsystems, today announced that it will 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 full digital control interface

• The demonstration will showcase the 800 Gbps optical link powered by Coherent’s 140 GBaud IC-TROSA, coupled with Marvell’s Orion DSP.
• The 140 GBaud IC-TROSA enables 0 dBm output power without the need for external amplification or tunable filters to achieve industry-leading performance. The IC-TROSA offers 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 contains 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 achieves 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 will participate in the OIF’s 400ZR/400G OpenZR+ and Common Management Interface Specification (CMIS) interoperability demonstrations.
• Coherent will showcase 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 highlights 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 will show 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 lowest power density to support legacy QSFP28 ports.
• The transceiver features Coherent’s Steelerton® DSP, the industry’s first purpose-built DSP for 100ZR applications that enables best-in-class power efficiency.
• Optimized for minimal power consumption and a compact form factor, this module pairs the Steelerton® DSP with a highly efficient silicon photonics optical front-end and a power-efficient internally developed tunable laser.
