PoE power supply distance of the switch
The standard PoE switch distance limit is 100 meters, as defined by Ethernet transmission properties. When the transmission distance exceeds 100 meters, data delay, packet loss, etc. Because the farther the distance, the greater the resistance, the higher the requirements. In PoE (Power over Ethernet) technology, the Ethernet link between the Power Sourcing Equipment (PSE) and the Powered Device (PD) has a clearly defined maximum distance limit—100 meters (328 feet). The pair 1-2 act as the positive polarity, while the pair 3-6 act as the negative polarity.

How many optical modules does an OLT device have
An OLT (optical line terminal), also known as optical line termination, acts as the endpoint hardware device in a passive optical network. The OLT contains a central processing unit (CPU), passive optical network cards, a gateway router (GWR) and a voice gateway (VGW) uplink cards. The OLT is responsible not only for transmitting data from the core network to user terminals but also for managing bandwidth. In general, an OLT is akin to a Network Switch where each port represents one or more client ONT or a node. It aggregates multiple ONUs/ONTs through optical splitters and handles data distribution, management, and synchronization. Optical Network Termination (ONT).
