This article is mainly to let everyone know how to replace the ONU of the little turtle with a PON; the full name of the ONU is Optical Network Unit, optical node; the full name of PON For Passive Optical Network, passive optical fiber network.▲ NOKIA G-040G-W ▽ PW: 40gw + mac last four yards▲ Alcatel-Lucent ▽ I-040G-W – PW: 40GW + mac last four yards ▽ I-040G-A – PW: 40GA + mac last four yards ▽ I-040G-B – PW: 40GB + mac last four yards▲ DASAN ▽ H660W – PW: 660W + mac last four yards / 60WM ++ mac last four yards ▽ H660WM – PW: 60WM + mac last four yards ▽ H660WM-C – PW: 0WMC + mac last four yards▲ Askey ▽ RTF-8207W – PW: 207W + mac last four yards▲ ZyXEL ▽ PMG4506-T20B – PW: t20b + mac last four yards▲ Chunghwa Telecom Obstruction Declaration ▽ F12, click "Broadband Internet Access Problems" to get the following information – getLineInfo – vendor (OLT model) – splno (line number) – vlan▲ ALCATEL-7360FX-8 – HW_HWVER – OMCI_SW_VER1 – OMCI_SW_VER2 – GPON_PLOAM_PASSWD – GPON_SN▲ ALCATEL-7342 – GPON_PLOAM_PASSWD – GPON_SN ▲ DASAN-V8272 – GPON_PLOAM_PASSWD – GPON_SN – OMCI_FAKE_OK (1/0) # If the verification fails the first time, try a few more times and it should pass, presumably a bug▲ DASAN-V8106 – GPON_PLOAM_PASSWD – GPON_SN – OMCI_FAKE_OK (1/0) # If the first verification fails, try a few more times and it should pass, presumably a bugPON cat stick information used in the test: – DFP-34X-2C2 based on Realtek RTL9601D; – Can successfully replace RTF8207W;▲ Find out the GPON SN of the little turtle ▽ RTF82xx – ASKYxxxxxxxx▲ Insert into SFP or SFP+ interface ▽ If there is no Up – Turn off Auto Negotiation – Specify the speed as 1Gbps-FDX or 2.5Gbps-FDX▲ Enter the PON cat stick WebUI – manually adjust the IP to: 192.168.1.x/24 – connect to the PON cat stick http://192.168.1.1 – admin / admin login▲ The initial state is on the Status - PON page. If the ONU State is found to be "O2", it means that the current authentication fails. There may be a problem with the firmware version. Generally, "O5" will appear if it is normal and no problem; Rx Power has a number.
