  • Does PoE power supply require an optical module

    Does PoE power supply require an optical module

    Although SFP modules themselves do not support PoE, they can be used in conjunction with a PoE-capable switch or injector to provide data and power to devices that require power supply. Power over Ethernet (PoE) describes any of several standards or ad hoc systems that pass electric power along with data on twisted-pair Ethernet cabling. This allows a single cable to provide both a data connection and enough electricity to power networked devices such as wireless access points. SFP modules are small pluggable optical modules commonly used for fiber optic transmission in network equipment, while PoE is a technology that allows power and data to be transmitted over Ethernet cables. So, does the SFP module support PoE? Let's explore it. While PoE doesn't add Ethernet data capabilities, it does offer expanded options for how and where Ethernet end devices can be. POE allows an Ethernet cable to carry DC power as well as data signals to attached devices. Ethernet cable (CAT 5,6 &7) uses 4 twisted pairs. All in all, this should be required reading for anyone who works with Ethernet, because it's one of those things too often presented as something of a black box.

  • Is it safe to hide a power distribution box

    Is it safe to hide a power distribution box

    Actually, despite the dangers that hiding boxes will cause, the law has also made a clear stipulation. 29, NEC stipulates that all junction boxes must be accessible for convenient maintenance, and parts of their structures and finish materials must remain to. Electrical boxes, which manage the main power supply or house utility meters, are necessary for any building's function and safety. Since these metal enclosures are rarely aesthetic, the desire to conceal them is understandable. Any modification, however, must prioritize safety and accessibility. Blocking or permanently sealing off an electrical panel can create serious safety hazards and might violate. While there are plenty of creative ways to conceal a breaker box, doing it the wrong way can lead to code violations or, worse, fire hazards. Here is everything you need to know about how to hide an electrical panel without compromising your safety. It contains switches, splices, sockets, wire connections, etc.
