Coherent Corp. (NYSE: COHR) has launched the first 100G ZR QSFP28 digital coherent optics (DCO) transceiver designed to operate over the industrial temperature range of -40°C to +85°C. The production release addresses the growing demand for robust, high-performance optical networking solutions in outdoor and harsh environments.
The I-temp 100G ZR QSFP28-DCO module operates at 5.5W, leveraging Coherent’s Steelerton™ digital signal processor (DSP) technology, silicon photonics optical front-end, and an Indium Phosphide-based tunable laser. This design achieves exceptional power efficiency in a compact form factor. The transceiver’s seamless integration of DSP and optics underscores the benefits of Coherent’s vertically integrated manufacturing approach, delivering high performance and scalability.
The module supports SFF-8636 and CMIS management interfaces, ensuring compatibility with existing QSFP28-equipped devices and enabling easy upgrades from 10G to 100G in edge and access networks. Features like Flextune™ auto-tuning simplify network deployment and operations. “This I-temp 100G QSFP28 coherent transceiver serves a growing demand from our customers,” said Christoph Glingener, CTO of Adtran. “It enables operators to easily upgrade their edge and access networks in the outside plant from 10 Gbps to 100 Gbps data rates, while lowering both capital and operational expenses.”
