The requirements cover balanced non-co

24、nnectorised single-mode IxN and 2xN 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 1 x2 and 2x2 devices because they are the most commonly used. 2 Normative refer

39、s ferminafed on single-mode fibre for cafegory U - Unconfrolled environmenf 3 Test All test methods are in accordance with the IEC 61300 series of standards. The samples shall be terminated onto single-mode fibres according to Type B1.l of IEC 60793-1-1 in either coated fibres (primary and secondary

40、) or reinforced cable format. Each test defines the number of samples to be evaluated. All tests shall be carried out to validate performance over the optical passbands of 1 260 nm to 1 360 nm and 1 480 nm to 1 580 nm. This is the minimum requirement for devices corres- ponding to Class 1 as describ

41、ed in 5.2. 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 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. O BSI 2
