Overview
IEC 62149-4:2010 is an international performance standard developed by the International Electrotechnical Commission (IEC) that specifies the requirements for 1300 nm fibre optic transceiver modules used in Gigabit Ethernet applications. This standard defines critical product performance parameters and establishes clear testing methodologies and acceptance criteria to ensure reliable operation of transceivers operating at 1.25 Gbit/s in accordance with ISO/IEC 8802-3 Gigabit Ethernet standards.
The 2010 edition represents the second revision, updating performance tables to reflect advances in fibre optic technology. It provides a robust framework for manufacturers and quality assurance teams to validate transceiver devices through prescribed once-off testing, guaranteeing compliance and interoperability in networking environments.
