See also ITU-T Recommendation G.983.1. 3.1.1 optical access network OAN set of access links sharing the same network-side interfaces and supported by optical access transmission systems Note 1 to entry: The OAN can include a number of ODNs connected to the same OLT. 3.1.2 optical distribution network ODN apparatus or component that provides the optical transmission means from the OLT to the users and vice versa Note 1 to entry: The ODN utilizes passive optical components.
5.4 Absolute limiting rating Absolute limiting (maximum) ratings imply that no catastrophic damage will occur if the product is subjected to these ratings, provided each limiting parameter is in isolation and all other parameters have values within the normal performance parameters. It should not be assumed that limiting values of more than one parameter could be applied at any one time.5.5 Functional specification Electro-optical characteristics for the items in Table 3 shall be satisfied at the operating environmental conditions specified in Table 2. Optical characteristics specified in ITU-T Recommendation G.983.1 should be satisfied. Each electrical and optical characteristic of 5.5 shall be measured under conditions specified in each reference. Each electrical and optical characteristic of 5.5 shall be stated under specified worst-case conditions, with respect to the recommended range of operating conditions as stated. The measuring method of each electrical and optical characteristics specified in Table 3 shall be measured based on the method stated in the reference of each row.
