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
 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.
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
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
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.
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.
instruction Record the optical module’s manufacturer, model and serial number.

Test remarks
3 PON Basic Function Test
3.1 LOID authentication function test of the ONU
environment Refer to Figure 1 for the test configuration
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
