Data transmission using fibre optic systems is increasingly commonplace. Proper marking of patch cords and pigtail wires saves time and money in the event of failure or upgrade. Partex recommends clip-on markers and/or self-laminating labels for this purpose. With them, you can easily replace a marker if you need to re-connect cables in the rack cabinet and change the connection labels. These markers can also be retro-fitted onto an existing system, without the need to disconnect cables.
