The work was initiated at CENELEC CLC/TC 86BXA in November 2004 in order to get a clear understanding on the accuracy and r
23、epeatability of the spectral attenuation loss measurements on fixed attenuators. Out of these results some recommendations are made for attenuation tolerance values that can be used in the performance standards. 2 Test samples In total 18 SC/APC plug style fixed attenuators were collected for this r
24、ound robin test: 6 attenuators with nominal attenuation of 1 dB (labelled 1, 2, 3, 4, 5, 6); 6 attenuators with nominal attenuation of 5 dB (labelled 7, 8, 9, 10, 11, 12); 6 attenuators with nominal attenuation of 15 dB (labelled 13, 14, 15, 16, 17, 18). The attenuators were obtained from various su
25、ppliers. The attenuating principle of all devices is based on the use of high attenuating fibre. The performance grade of these attenuators is defined as operating wavelength range: 1 260 nm - 1 360 nm and 1 460 nm - 1 580 nm, attenuation tolerance: 0,5 dB for attenuators 5 dB, 10 % of nominal atten
26、uation value for attenuators 5 dB. 3 Test program All participating test laboratories measured spectral attenuation and polarisation dependent loss for each attenuator. For the sake of decreasing uncertainty all measurement procedures were specified in necessary details. 3.1 Spectral attenuation los
27、s (according to EN 61300-3-5) The measured values were reported for the discrete wavelengths in the full spectral range from 1 260 nm to 1 650 nm with 5 nm step. The spectral width was set at 2 nm. To minimize uncertainty of measured results, measuring equipment specifications and measurement proced
28、ures were clearly stated. Each test laboratory performed the measurements with 2 sets of plugs and adapters: measurements with common reference plugs and adapter (the same references for all the test laboratories); measurements with own Grade B plugs and own adapter. Estimated measurement uncertaint

30、3-2 method 1) PDL was measured at 1 310 nm and 1 550 nm, with common reference plugs. Selected measurements method was “all states method”. The accuracy of each PDL measurement was better than 0,1 dB. 4 Test laboratories involved in this RRT The following laboratories were involved in this round rob
