25、 for Category U Uncontrolled environment 1 Scope This part of IEC 61753 contains the minimum initialisation test and measurement require- ments and severities which a branching device shall satisfy in order to be categorised as meeting the IEC standard. The requirements cover balanced non-connectori
26、sed single-mode 1N and 2N non-wavelength-selective branching devices for use in an IEC Category U environment (N is the number of output ports). The specifications of unbalanced branching devices are limited to 12 and 22 devices because they are the most commonly used. 2 Normative references The fol

Extensions to these windows are covered by classes 2 and 3. Class 2 specifies additional attenuation limits for 1 450 nm to 1 480 nm and
43、 1 580 nm to 1 600 nm. Class 3 devices shall meet Class 2 requirements and additionally have defined attenuation limits for 1 600 nm to 1 650 nm.
