Which port of the core switch should the OLT connect to
The OLT receives and transmits the Ethernet services to the GPON Encapsulation Method (GEM) ports. Each GEM port is identified by a unique ID called port ID. Application Scenario An apartment wants to use the XM60A to enable Omada equipment to access the OLT for networking and flexible deployment. These ports send data to the end users. An OLT, generally an Ethernet switch, router, or multimedia conversion platform, is located at the central office (CO) as a core device of the whole EPON system to provide core data and video-to-telephone network interfaces for EPON and the service provider. ONUs are used to connect the customer. Each port connects to a splitter (1:8 to 1:64), so a single 4-port OLT can serve up to 256 subscribers.

Can a powered PoE switch be connected to another switch
Yes, you can connect two PoE switches together, and this is a common scenario in many networking setups. The power draw would be too great. While it is quite rare and has power limitations (as incoming power has to be split accross child connections). PoE devices are network equipment that can send out or receive the PoE power along with data, such as PoE switches, IP cameras, wireless access points, while non-PoE devices can only. PoE (Power over Ethernet) technology allows switches to deliver both power and data over a single Ethernet cable—perfect for powering devices like IP cameras, VoIP phones, and wireless access points. But not all devices and switches support PoE.
