Is it better to use network cables or fiber optic cables for cascading PoE switches
While Ethernet cables are ideal for short-range connectivity and Power over Ethernet (PoE) systems, fiber optics are unmatched in bandwidth and reliability over extensive distances. Choosing between fiber optic cable and Ethernet (copper) cable is critical for network performance, cost, and scalability. Both cable types offer distinct advantages, but their strengths serve different priorities. Fiber optics. When setting up a new network, one question always comes up: Should you use fiber or Ethernet cables? Both carry data. And they don't serve the same needs. Local area networks (LANs) and data centers have long been comprised of both copper and fiber cables to establish backbone links between active equipment and horizontal links to connect a wide range of end devices.

Will optical splitters affect network bandwidth
Splitters only lower the optical power—not the bandwidth. Every endpoint still gets the full data stream; the light is just a little dimmer. And here's where optical networks shine (literally): even with that tiny power drop, a single fiber can carry so much data that performance. Bandwidth is shared amongst customers in a PON, and the bandwidth received by a customer is not related to the power received at the optical network terminal (ONT) as long as the power is high enough so the ONT can operate. Splits are most commonly factors of 2, such as 1x2, 1x4, 1x8, 1x16, 1x32. In the backbone of modern Fiber-to-the-Home (FTTH) networks, optical splitters serve as the unsung heroes that enable cost-efficient connectivity for millions of subscribers. By dividing a single optical signal from a central Optical Line Terminal (OLT) into multiple outputs for Optical Network. With higher split ratios, the PON network has both advantages and disadvantages.
