This part of IEC 62149 covers the performance specification for radio-over-fibre (RoF) transceivers used for mobile fronthaul systems. The performance standard contains a definition of the product performance requirements together with a series of tests and measurements with clearly defined conditions, severities, and pass/fail criteria. The tests are intended to be run on a one-off basis to prove any product's ability to satisfy the performance standard's requirements.

A product that has been shown to meet all the requirements of a performance standard can be declared to be in compliance with the performance standard.
