PD IEC/TR 62721 discusses the reliability of devices used in fibre optic systems. Fibre optic systems are the technology used to transmit information as pulses of light through strands of fibre made of glass or plastic over long distances. PD IEC/TR 62721 provides information on the IEC documents concerning reliability for optical fibres, optical connectors, optical passive components, optical active components, optical amplifiers, and optical dynamic modules used for optical fibre communications.
PD IEC/TR 62721 include summaries of reliability theory and quality management methods, technical information on failure mode analysis and failure mechanisms, lifetime and fit-rate estimates using acceleration tests, test items, conditions, and pass/fail criteria in reliability qualification tests, and tests and measurement methods for optical fibres, optical components, and optical modules. Each SC in TC86 has already created documents on reliability. PD IEC/TR 62721 provides this information in a user-friendly manner.
PD IEC/TR 62721 on the reliability of devices used in fibre optic systems is useful for:
Optic systems are about the diameter of a strand of human hair and when bundled into a fibre-optic cable, they’re capable of transmitting more data over longer distances and faster than other mediums. PD IEC/TR 62721 defines TC86 (Fibre optics) as a group that reviews and implements the standardization of optical fibres and optical cables, optical interconnecting devices, passive and active optical components and modules, and optical sub-systems. As these optical components and modules are used for telecommunications as well as data communications systems, the reliability required for these is extremely high. Since the 1980s, when fibre optic communication systems were first deployed for commercial use, the reliability of optical fibres, optical components and modules has been examined and checked. As a result, reliability theories are nearly completely established for optical fibre, optical connectors, optical passive components, and optically active components.
In addition, the industry has established and uses standard reliability evaluation tests developed for the purpose of commercialisation in addition to the approach of estimating the lifetime by failure mode analysis mentioned. Information on failure mode and lifetime estimates are discussed and summarised in many documents prepared by the Subcommittees (SC) and Working Groups (WG) of TC86. Test items and conditions for reliability qualification tests are described in PD IEC/TR 62721 which is prepared and set forth by each SC. Using PD IEC/TR 62721 you can provide information on the IEC documents concerning reliability for optical fibres, optical connectors, optical passive components, optical active components, optical amplifiers, and optical dynamic modules used for optical fibre communications.
