Can a regular switch be used as a PoE switch
If you need to connect PoE devices using a normal (non-PoE) switch, you must insert a PoE injector between the switch and each device. The injector adds power to the Ethernet line and requires a separate power source. While both serve the same basic function of connecting network devices, a PoE switch offers built-in Power over Ethernet (PoE) capabilities that can significantly simplify deployment and reduce costs in certain scenarios. These switches follow IEEE standards such as 802.

What size clamp should be used for a 24-core fiber optic cable
For 24-core ADSS on spans ≤300 m, preformed rod suspension clamps are the standard choice — they distribute load across the armor rod length and are less sensitive to installation torque errors than wedge types. When managing large cable bundles—whether they include thick Ethernet runs, multi-strand fiber trunks, or low-voltage power cables—the right cable clamp configuration plays a major role in long-term reliability, safety, and organization. Using properly sized and appropriately spaced clamps prevents. That breadth is useful for a general audience, but it leaves a gap: the engineer who only needs to spec clamps for a 24-core ADSS project does not want to scroll past 96-core span tables to find what applies to their cable. This article focuses exclusively on 24-core ADSS — the workhorse fiber. In 4G/5G networking, the telecommunication projects will use more and more combined cable clamps, which need to fix both power cables (DC) and fiber optic cables (FO). Volda supplies a broad spectrum of fiber cable clamps, for example: 4-7mm, 6-9mm, 4.

Intelligent optical circulator used in Greek FTTR
An optical circulator is a three- or four-port designed such that entering any port exits from the next. This means that if light enters port 1 it is emitted from port 2, but if some of the emitted light is reflected back to the circulator, it does not come out of port 1 but instead exits from port 3. This is analogous to the operation of an electronic. Fiber-optic circulators are used to separate optical signals.
