What this standard covers

This standard specifies the abbreviations, terms and definitions, technical requirements, test methods, etc. of the built-in wavelength selective reflector for ONU optical modules used in OTDR testing. This standard applies to wavelength selective reflectors built into ONU optical modules in passive optical network (PON) systems. The OTDR center wavelengths used are 1490nm, 1625nm and 1650nm. Optical modules of other dedicated telecommunications networks have built-in wavelength selective reflectors, or wavelength selective reflectors that use other center wavelengths such as 1577 nm for OTDR testing.
