“Structured cabling” may lead you to believe that the system is only made of cables in your data centre, but that’s not quite the case. A structured cabling system runs throughout a building or across a campus, with different points and dedicated areas.
Besides cables, structured cabling solutions can include racks, network cabinets, hardware ports and more. All of these smaller pieces work together as part of the overall system.
The standardized elements that make up structured cabling are called “subsystems.” These subsystems are typically located across a building, so it’s important to know where they’ll be in your business location.
Six different kinds of subsystems go into structured cabling.

These days are all share them with me oh baby so let’s make the most We all know about maintenance. We know things wear out or get dirty and need replacing or cleaning. This is especially true about cars. We regularly change the oil and filter, rotate the tyres, and get the engine tuned up to keep our vehicles running well. It’s also true for our tools, our homes, and more. Preventative maintenance is a good idea for most things. For some things, however, the old adage “if it ain’t broke, don’t fix it” could apply. That statement applies to fibre optic networks. The properly installed fibre optic cable plant needs no periodic maintenance. Attempting maintenance may harm more than help! Let’s consider a few factors that harm fibre and see how to prevent problems. Dirt is your enemy Perhaps the biggest problem with fiber optic cabling systems is dirt. Dirt can scratch the ends of the connectors during the termination process. These scratches produce a high loss in mated pairs of connectors. Dirt can get on the ends of the connectors when they are exposed to the air and cause both high loss and high back reflection. Unless you store unconnected fibre optic cables and patch panels with dust caps, dust will get into the mating adapters and onto the ends of the connectors. While connectors can be cleaned with lint-free pads and isopropyl alcohol (no cotton swabs, please, as they leave threads that can be as harmful as dirt), the mating adapters are very difficult to clean properly. The best solution we have found is the “Curtis Blaster,” available in office supply stores, which is designed to clean computer parts. The same warning about dirt applies to networking equipment too. Keep dust caps on every fibre optic interface! Fibre optic cable is rugged, but… Fibre optic cable is very rugged. It can be pulled to hundreds of pounds of tension during installation, as long as it is not bent too tightly, and crushed with large loads. Too much tension or too-tight bends might not break the glass fibre, but it may cause degradation in the fibre. Excess tension causes the cable to stretch and, when it relaxes, the fibre may be pinched as the cable contracts.
Alignment and condition monitoring instruments require proper mainte- nance, care and calibration at specific intervals to achieve the highest possible measurement reliability and accuracy. Please refer to the individual operating manuals for the recommended recalibration inter- val. In most cases calibration accuracy checks are conducted every two years.
Poorly maintained alignment systems may lead to inaccurate measure- ments and incorrect results. All calibrations are performed in our high-tech test and measurement lab by our Service Team.
The standards and standard measurement equipment used for calibra- tion are re-calibrated at specific intervals according to the standards of the German PTB (Physikalisch- Technischen Bundesanstalt) and other national standards.
MARKINFOTECH Service Center helps you achieve an optimal, long-lasting alignment of your machines.

Simple, reliable and field-proven test procedures have long been established for certifying that an optical fibre cabling system is correctly installed. Proper testing maximizes system longevity, minimizes downtime and maintenance, and facilitates upgrades and reconfigurations. Documenting test results quantifies system quality, identifies potential cable and component faults, and establishes accountability when several vendors are involved.
• Ensure the power meter is calibrated at each of the nominal test wavelengths and traceable to the National Institute of Standards and Technology calibration standard.
• Set the power meter end and the light source to the same wavelength.
• Clean all system connectors, adapters and jumpers before measurement.
• End-to-end attenuation test
End-to-end attenuation testing measures the total amount of loss between two endpoints. To find out what causes this loss and where it occurs in the cable system, an optical time-domain reflectometer is needed. An OTDR can locate fibre events and measure the losses attributable to cable, connectors, splices and other components. The graphi- cal display of loss over a cable’s entire length provides the most reveal- ing analysis and documentation available on a cable link; this is com- monly referred to as the link’s signature trace.
