36、ANDARD Part 031-2: Non-connectorized single-mode 1N and 2N non-wavelength-selective branching devices for Category C Controlled environment 1 Scope This part of IEC 61753 contains the minimum initial tests and measurement requirements and severities which a non-wavelength selective branching device
37、(NWBD) should satisfy in order to be categorized as meeting the requirement of this IEC standard. The requirements cover balanced bidirectional non-connectorized single-mode 1 N and 2 N non wavelength-selective branching devices for use in an IEC Category C environment (N is the number of branching
38、ports), especially but not exclusively used for PON application. For balanced NWBD two attenuation and uniformity performance classes are considered: class A (premium class) which meets more restrictive requirements (i.e. for extended reach PON application) and class B (standard class) for standard
39、application (i.e. normal reach PON application). The requirements also cover unbalanced bidirectional non-connectorized single-mode, non-wavelength-selective branching devices; however, the specifications of unbalanced branching devices are limited to 1 2 and 2 2 devices because they are the most co
40、mmonly used. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
