O Power over Ethernet é seguro?
Power over Ethernet (PoE) has been around now for several years, starting with Type 1 PoE (IEEE 802.3af) introduced in 2003 that delivers up to 15,4 W, with 13 W available for the device. That was followed by Type 2 PoE (sometimes referred to as PoE Plus) that delivers up to 30 W, with 25,5 W available for the device.

Extending and Testing Cable Runs Beyond 100 meters
In our last article on how to connect end devices beyond copper Ethernet’s 100 meter range, we looked at various solutions to the dilemma of needing to connect an end device that’s just a little too far from the nearest telecommunications room (TR), including building a new TR, the use of an extender device, fiber or extended-distance cabling.

Breaking the 100-Meter Barrier
It’s a common problem – you need to connect an end device that’s just a little too far from the nearest telecommunications room (TR). While industry standards limit the length of a channel to 100 meters, connecting the device maybe require a channel length of 150 meters or even 200.
There are four ways to address this problem. Let’s take a look at the options and their pros and cons.

Physical Infrastructure Management Reduces Network Downtime
Planet IRM and Fluke Networks have integrated LinkWare Live into the Planet Infrastructure Relationship Management software solution, allowing customers to access detailed cable test results from their physical asset network diagrams, providing a view we like to call “from network map to wiremap”. We asked the team at Planet to introduce their solution and the benefits of the integration – their article is below.
