Hi everyone, A few days ago, my home was finally upgraded to FTTH from VDSL! Swisscom sent me a SFP module and a patch cable to use with my Internet Box 3. The module is a WTD XGS PON ONU RTXM166-702 SFP+. The fiber optic plug in the wall is green and the Swisscom patch cable is green on the wall side and red on the IB3 side. Internet works fine with the IB3. When the technician came to install the fiber plug in the wall, he tested the connection on an IB3 with a HiSense LTF7225 SFP+ XGSPON ONU. I'm trying to get rid of the IB3 and connect directly my switch/router to the fiber. Mikrotik CRS328-24P-4S+RM: https://mikrotik.com/product/crs328_24p_4s_rm RouterOS 6.48.6 I purchased this SFP module based on a recommendation in some other thread of this forum: https://www.tp-link.com/en/business-networking/accessory/tl-sm321b/ I purchased this patch cable (LC/APC-LC (Simplex) - 1m): https://www.prodimex.ch/lightwin-fibre-optic-cable-singlemode-lc_apc-lc-%2528simplex%2529-1m-lsp-09-lc_apc-lc-1.0-99600.html I have applied the configuration mentioned above: /interface vlan
add interface=sfp-sfpplus1 name=FTTH vlan-id=10
/ip dhcp-client option
add code=60 name=swisscom value="'100008,0001'"
/ip dhcp-client
add dhcp-options=hostname,clientid,swisscom disabled=no interface=FTTH use-peer-dns=no use-peer-ntp=no I plug-in the SFP module in sfp port #1, plug-in the patch cable (blue end in the SFP module and green end in the wall plug): the module is seen by the Mikrotik, it shows send / receive signal, but there's no link and the interface is not reported as running. I also tried plugging into the Mikrotik the Swisscom-provided SFP module, but same result. How do I debug this? PS: For context, I've already browsed the forums extensively and I'm a software engineer by trade very familiar with networking, and I've been using RouterOS for years. However, I do not know anything about FTTH. PS3: When using VDSL previously, I had successfully replaced the IB3 with a VDSL modem in bridge mode so I'm already familiar with the DHCP option 60, going to swisscom/start, etc...
