A method for identification of Start and End of Cat5 cables using bistable multivibrator LEDs

Data Centres, conference rooms and other meeting rooms have a number of Cat5

Ethernet cables used by a variety of devices.

    These cables may need to be pulled out from network sources for maintenance, shutdown, travel, etc. and often result in wrong cables being pulled resulting disruption of service

    A number of tools and methods currently exist to solve this problem, such as those using manual labelling, colour coding, self-adhesive labels, etc. The following patents were discovered during initial search:

(This page contains 00 pictures or other non-text object)

    The present invention proposes adding low power, multivibrator bi-stable LEDs to the Cat5 Pins (also called 8P8C plug pin), along with a button and LCD display,

which will be powered utilising the Power over Ethernet


Ethernet) standard.

    This will allow the ends of the cables to be identified uniquely when the button at one end is pressed, mitigating the human errors when the cables have to be pulled from the ports they are plugged into.

In the present disclosure, an LED and a small button with a bevelled edge is added to each 8P8C modular plug ping. The flashing circuit of the LED uses the classic multivibrator bistable circuit. The LED does not flash normally, but will emit a light

when the button is depressed on the plug ping at the other end of the cable

will allow users to uniquely identify the cabl...
