The test contents of this specification include. ONU PON interface test, PON basic function test, Layer-2 function test, security test, multicast test, ONU Layer-2 function test, OMCI interoperability test, local management and remote management test. 1.1 Equipment profile 1.1.1 OLT Equipment model PON chip Shape (diagram) Dimension (W/H/D mm) Weight Power supply Power Number of Slots Control panel (whether support main and standby redundancy) Rear panel switching capability PON number of ports (single board/entire device) Number of uplink interfaces 10GE GE (optical/electrical) FE STM-1 E1 1.3.2 Version of the tested equipment Description Model Hardware Version Software Version Test Remarks Network management OLT Main control board PON panel PON chip Uplink board Switching chip Optical module Others ONU Optical splitter Indicate manufacturer and type 1.3.3 Networking topology of the testing equipment Refer to Figure 1 for the topology structure of the testing system of GPON equipment. The configuration of such testing system is mainly used for testing the interoperability, basic function, system performance, and network management function. Such system consists of Optical Line Terminal (OLT), Optical Network Unit (ONU), passive optical splitter, and the supporting instruments and equipment; whereof the Optical Distribution Network (ODN) adopts passive optical network structure of passive optical splitter; a trunk optical fiber connects with several optical fibers, communicates with multiple ONUs, which can share the upstream bandwidth through the passive optical splitter. dial-up networking, STP and other equipment  VLAN2 is routing mode, dedicated channel for TR069; the users’ application equipment (e.g. PC, STB, and etc.) can’t access to internet through this channel.  VLAN3 is routing mode, dedicated channel for VoIP, users’ networking equipment (e.g. PC), IPTV device (e.g. STB) can’t access to internet through this channel.  When accessing to the internet, users’ networking equipment (e.g. PC) must visit 1FE+1POTS SFU equipment. The OLT and ONU devices involved into this test can come from different manufacturers. accuracy; 6. Adjust the optical attenuator, so that the power value shown by the PON optical power meter reach about -25dBm; repeat Procedure 3 to verify its measurement accuracy; 7. Adjust the optical attenuator, so that the power value shown by the PON optical power meter reach about -30dBm; repeat Procedure 3 to verify its measurement accuracy; 8. Set the low threshold of optical power received by ONU on the network management to be -20dBm; adjust the optical attenuator, gradually increase the attenuation value; when OLT downstream optical power received by ONU is lower than the setting optical power threshold, observe whether the network management shall generate corresponding over-limit alarm. 9. Read the ONU parameters like operating temperature, power supply voltage, bias current and sending optical power through OLT; verify whether ONU supports the measurement of its own optical module parameters. Expected results 1. In Procedure 2. ONU can support the measurement of the downstream optical power of the OLT.. 2. In Procedures 3~7. within the range of -10dBm~-30dBm, the measurement accuracy of downstream optical power of ONU against OLT is ±2dB. 3. In Procedure 8. ONU supports over-limit alarm when receiving optical power, and the optical power threshold can be set. 4. In Procedure 9. ONU supports the real-time measurement of parameters of its own optical module, like operating temperature, power supply voltage, bias current, sending optical power. Test instruction Record the optical module’s manufacturer, model and serial number. Test results Procedure 3 Procedure 4 Procedure 5 Procedure 6 Procedure 7 Procedure 8 Procedure 9 Optical module’s manufacturer, model, and serial number. Test remarks 3 PON Basic Function Test 3.1 LOID authentication function test of the ONU instrument Test environment Refer to Figure 1 for the test configuration Test procedures 1. Establish test environment according to the test configuration diagram of Figure 1; 2. Disconnect the optical fiber on the ONU interface; 3. Start the LOID authentication function of OLT, and set it to be authenticated according to LOID and password; configure a valid LOID and corresponding password on the EMS/CLI (note that avoid using the same ID saved in ONU currently); 4. After connecting the optical fiber, connect the ONU to OND; 5. Check whether the ONU can be authenticated on the EMS/CLI of the OLT; 6. Disconnect the optical fiber on the ONU interface; 7. Configure the LOID locally on the ONU, its value shall be consistent with LOID configured on EMS/CLI in Procedure 3; check whether the ONU is restarted; 8. Connect the ONU optical fiber, reconnect ONU to the ODN; 9. Check whether the ONU can be authenticated on the EMS/CLI of the OLT; 10. Disconnect the optical fiber on the ONU interface; 11. Configure corresponding password of LOID locally on the ONU, its value shall be consistent with the password configured on the EMS/CLI... ......
