31、010 INTRODUCTION This International Standard specifies testing and measuring procedures for optoelectronic properties of asynchronous-transfer-mode passive optical network (ATM-PON) transceivers. The package interface dimensions and optoelectronic performance of the transceivers are defined in IEC 6
32、2148-6 and IEC 62149-5, respectively. g37g54g3g40g49g3g25g21g20g24g19g16g21g29g21g19g20g2062150-2 g148 IEC:2010 7 FIBRE OPTIC ACTIVE COMPONENTS AND DEVICES TEST AND MEASUREMENT PROCEDURES Part 2: ATM-PON transceivers 1 Scope This part of IEC 62150 specifies testing and measuring procedures for fibre
33、 optic transceivers for asynchronous-transfer-mode passive optical network (ATM-PON) systems recommended by ITU-T G.983.1. These testing procedures correspond to methods of examining whether the transceivers satisfy the performance specifications defined in IEC 62149-5. On the other hand, the measur
34、ing procedures correspond to methods of precise measurement for such transceivers. The receiver sections of these transceivers can handle burst signals. Therefore, some procedures described in this standard correspond to the burst signal transmission. 2 Normative references The following referenced
