Does the optical port on the switch have to be LC
Most modern fiber-enabled network switches require an SFP transceiver module featuring a duplex (two strand) multimode OM3 or duplex single mode OS2 connection with LC connectors. Direct attach cables with pre-terminated SFP connections may also be used. Why Fiber Connector Choice Actually. Switch optical modules, which convert electrical signals to optical signals and vice – versa, and optical interfaces, which serve as the physical connection points, play a pivotal role in determining the speed, distance, and reliability of data transmission. Common optical module types such as SFP. Fiber optic adapters serve an important role as “connector translators” between incompatible connector styles while maintaining proper physical and optical alignment. Without the proper adapter, signals can degrade or become unstable, which can dramatically decrease the reliability of a network. During the installation at the point where the fiber cable has to be plugged and/or unplugged you need to switch up your strategy and put a connector of some kind on.

What is the maximum distance for a PoE switch
The standard PoE switch distance limit is 100 meters, as defined by Ethernet transmission properties. 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). This means that a PoE switch can reliably supply power to a compatible device up to this distance. When you use a midspan, you should calculate the distance between the camera and the switch that the midspan is connected to.
