Next-Generation of Optical Ethernet PHY Transceivers Deliver Precision Time Protocol and MACsec Encryption for Long-Reach Networking

CHANDLER, Ariz., Oct. 30, 2025 (GLOBE NEWSWIRE) -- The rise of smart factories, remote monitoring and connected infrastructure are increasing the demand for advanced networking systems that can operate over long distances and in challenging environments. To address the need for reliable and secure connectivity solutions, Microchip Technology (Nasdaq: MCHP) today announces its new portfolio of Optical Ethernet PHY transceivers, available in 25 Gbps and 10 Gbps versions, featuring IEEE® 1588 Precision Time Protocol (PTP) and Media Access Control Security (MACsec) encryption.

Microchip’s optical Ethernet PHY transceivers provide a secure, deterministic and scalable alternative to traditional copper-based Ethernet solutions. They support link lengths of up to 10 kilometers over single-mode fiber for seamless deployments over dispersed infrastructure such as company and college campuses or warehouses. The integration of PTP time stamping delivers sub-nanosecond (
