22、rried out on SC/PC plug style fixed attenuators. The work was initiated at CENELEC TC 86BXA meeting in June 2003 in order to get a clear understanding on the accuracy and repeatability of the spectral attenuation loss measurements on fixed attenuators. Out of these results some recommendations are m
23、ade for attenuation tolerance values that can be used in the performance standards. 2 Test samples In total 18 SC/PC plug style fixed attenuators were collected for this round robin test: - 6 attenuators with nominal attenuation of 15 dB (labelled 1, 2, 3, 4, 5 and 6); - 6 attenuators with nominal a
24、ttenuation of 5 dB (labelled 7, 8, 9, 10, 11 and 12); - 6 attenuators with nominal attenuation of 1 dB (labelled 13, 14, 15, 16, 17 and 18). The attenuators were obtained from various suppliers. The attenuating principle of all devices is based on the use of high attenuating fibre. The performance g
25、rade 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 attenuation value for attenuators 5 dB. 3 Test program All participating test laboratories measured spectral attenuati
26、on and polarisation dependent loss for each attenuator. 3.1 Spectral attenuation loss (according to EN 61300-3-5) For the ease of the data processing the measured values were reported for the discrete wavelengths: 1 260 nm, 1 280 nm, 1 310 nm, 1 330 nm, 1 360 nm, 1 460 nm, 1 490 nm, 1 520 nm, 1 550
27、nm, 1 570 nm and 1 580 nm. The spectral width was set at 2 nm. Some laboratories also reported values with a spectral width of 10 nm. Each test laboratory performed the measurements with 2 sets of reference connectors and adapters: - measurements with common reference connectors and adapter (same re
28、ferences for all the test laboratories); - measurements with own test laboratory reference connectors and adapter. Uncertainty of each loss measurement at the above mentioned wavelength range was better than 0,1 dB. 3.2 Polarisation dependent loss (PDL) (according to EN 61300-3-2, option 1) PDL was
29、measured at 1 310 nm and 1 550 nm, with common reference connectors. 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 robin test (in alphabetic order): - Adamant Kogyo Co. Ltd (Japan); - Diamo
30、nd (Switzerland); - Huber and Suhner (Switzerland); - Telekomunikacja Polska (Poland); - TILab (Telecom Italia Laboratories) (Italy); - Tyco Electronics-AMP (the Netherlands); - Tyco Electronics-Raychem (Belgium).
