Coherent Corp. (NYSE: COHR) has unveiled a revolutionary multi-rail optical transport solution that combines high-efficiency pump lasers with resource pooling to increase line system capacity while reducing size and power consumption. The technology will be showcased at OFC 2025.

The demonstration features two independent rails carrying C-Band transmission signals in a single 1RU module, achieving double the density compared to current benchmarks. The solution includes dual-chip high-power uncooled pumps, multi-port optical channel monitoring, and multi-rail dynamic gain equalization technology.

The technology is designed to scale up to provide an eightfold increase in capacity while consuming significantly less space and power compared to traditional single-rail solutions. General product availability is expected in the first half of 2026.

Coherent Corp. (NYSE: COHR) has announced the general availability of the industry's first 100G ZR QSFP28-DCO with 0dBm optical output power, designed for metro and regional ROADM-based line systems. This high-power coherent transceiver features:

- Compact QSFP28 form factor with reduced power dissipation and network footprint
- Eliminates need for costly muxponders and transponders
- Optional Tunable Optical Filter for colorless ROADM configurations
- Built with InP photonic integrated circuits and in-house digital signal processor

The product targets IP-over-DWDM deployments, enabling network operators to upgrade metro DWDM networks from 10G to 100G while addressing capacity bottlenecks for bandwidth-intensive services like mobile video, autonomous cars, and AI inference.

Coherent Corp. (NYSE: COHR) has announced the general availability of its 800G ZR/ZR+ QSFP-DD transceiver, designed for high-speed optical networking applications. The new module supports transmission spanning over 500 km in ZR mode and beyond 1000 km in ZR+ modes, with capabilities extending to 2000 km at lower data rates.

The transceiver features proprietary Indium Phosphide chip technology, delivering transmitter optical output power of -7dBm for OIF 800ZR and 0dBm for ROADM-based systems. Unlike silicon photonics solutions, it operates without additional EDFAs or tunable optical filters, reducing complexity and costs.

The product enables IP-over-DWDM deployments in routers and Ethernet switches, eliminating standalone transport equipment and reducing operational costs. According to Cignal AI, over 70% of coherent bandwidth deployed in 2024 was in pluggables, with growth expected due to AI-driven data center interconnect demands.

Coherent Corp. (NYSE: COHR) has unveiled new pluggable optical transceivers specifically designed for data centers using optical circuit switches (OCSs). The innovation addresses the additional 3 dB insertion loss introduced by OCSs in AI and machine learning applications.

The company has adapted three optical standards to create transceivers that meet both IEEE-defined network insertion losses and OCS-related losses. The new lineup includes 400G FR4, 2x400G FR4, and 2x400G LR4-6 standards in QSFP-DD and OSFP form factors, supporting reaches up to 6 km for hyperscale data centers. Coherent also plans to release an OCS-optimized 1.6T FR8 transceiver in the future.

These new transceivers maintain compatibility with conventional transceivers when OCS is not used, while also working with other OCS-optimized transceivers, providing deployment flexibility.

Coherent Corp. (NYSE: COHR) has unveiled the industry's first 400 Gb/s Differential Electro-absorption Modulated Laser (D-EML) at OFC 2025, advancing high-speed optical networking for data centers. This innovation builds upon their successful 200G D-EML, which received recognition in the 2025 Lightwave+BTR Innovation Reviews.

The differential design doubles signal amplitude while reducing power consumption and minimizing crosstalk, delivering superior OMA and ER performance. The D-EML features integrated on-chip termination network for optimized electrical performance and is designed for low-cost, non-hermetic packaging solutions.

The 400G D-EML will be available under controlled availability, while the 200G D-EML is expected for general release in 2026. Demonstrations will be held at OFC 2025 in San Francisco, April 1-3 at booth #1519.

Coherent Corp. (NYSE: COHR) has announced plans to sell its epitaxial fabrication facility in Champaign, Illinois, as part of its manufacturing footprint optimization strategy. The 65,000 ft² campus includes four buildings and features five G3 epi systems within 15,000 ft² of Class 1000 ballroom-style cleanrooms.
