For Immediate Release


PITTSBURGH, March 25, 2024 (GLOBE NEWSWIRE) – Coherent Corp. (NYSE: COHR), a global leader in optical communications components and subsystems, announced today that it will showcase its new products and technologies for next-generation optical communications networks at OFC 2024, March 26-28 at the San Diego Convention Center, Booth #3412. Coherent thought leaders will present at panels, technical sessions, and other OFC events.


Bandwidth improvement in Coherent’s vertical-cavity surface-emitting laser (VCSEL), paving the way for use in next-generation optical interconnects that will operate at 200 Gbps per lane. 200 Gbps VCSELs are expected to power future 1.6 Tbps transceivers.

6-inch InP wafer fabrication introduced in both Coherent’s U.S. and European fabs to significantly reduce die cost for InP optoelectronic devices including lasers, detectors, and electronics.

Industry-first 100G ZR QSFP28 digital coherent optics (DCO) transceiver supporting an industrial operating temperature range; designed for deployment in outdoor environments, this module utilizes Coherent’s Steelerton™ digital signal processor (DSP), a purpose-built DSP component family launched in 2022, in conjunction with an efficient silicon photonics optical front-end and a power-optimized tunable laser.

New uncooled pump laser modules able to deliver, in a compact 10-pin form factor, up to 1000 mW of output power for submarine applications and up to 2x700 mW of output power for terrestrial applications.

Bi-di circulator adaptor based on Coherent’s vertically integrated circulator technology that enables bi-directional transmission over a single fiber between two transceivers in a compact footprint compatible with all transceiver LC connector ports.

A groundbreaking family of advanced, aberration-correcting, high-efficiency grisms and transmission gratings capable of encompassing the entire extended C+L band in a single optic.

Comprehensive and versatile platform for advanced collimation, focusing, and beam-shaping capabilities in a highly compact package: ideal for high-speed communication transceivers and modules, optical circuit switches, and LiDAR systems.



300x300 port Datacenter Lightwave Cross-Connect (DLX™), an optical circuit switch based on the company’s field-proven and ultrareliable digital liquid-crystal technology to enable new AI network architectures that replace traditional packet switches with optical circuit switches.

  • 200G per lane Linear Pluggable Optics for 800G

Demonstration of linear pluggable optics performance with 200 Gbps PAM4 electrical and optical lanes in an 800G-DR4 transceiver platform.

Demonstration of 800G QSFP-DD-DCO in various setups: over an optical link of 450 km fiber, in datacenter router, and at OIF booth with 400G and 800G interoperability demo.

  • 100G ZR QSFP28-DCO I-Temp Module
    Demonstration of the industry’s first 100G QSFP28 ZR supporting an industrial operating temperature range (-40°C to 85°C). The coherent transceiver is integrated with in-house purpose-built DSP, silicon photonics optical engine, and tunable laser.
  • C+L-Band Transport Product Modules

Demonstration of ultrawide-band OCM, C+L-band EDFA, and 3x33 Flexgrid® C+Lband twin wavelength selective switch (WSS) to meet the increasing demand for the expanded transmission bandwidth in DCI, metro, and long-haul applications.
