How the Environment Affects Your Structured Cabling!

We've all heard that structured cabling is the unsung hero that keeps our organizations running. But as any good structured cabler knows, the environment plays a big role in that cabling's longevity. Here are some things to watch out for and how to protect your precious cables.


While temperature extremes, moisture, and airborne contaminants present serious cabling threats, perhaps one of the most overlooked environmental factors is physical damage risks. This is especially important to consider for facilities located in dense, active urban environments throughout the San Francisco Bay Area.


As networks expand and are relied upon more heavily in these complex infrastructure settings, existing cable runs are often disturbed or added onto without consideration for the original installation quality or pathway integrity. Even the slightest abrasion over time can cause microscopic conductor breaks within copper cables. Those tasked with infrastructure stewardship of Bay Area facilities would be wise to carefully document existing runs and rigidly enforce cable pathway guidelines during any renovation or additional work. Only by preserving physical cable protection can we prevent cumulative degradation and avoid unnecessary early replacements in these mission-critical environments.

Temperature Swings are Tough on Cables


Dealing with temperature changes is tough on any material, and structured cabling is no exception. Excessive heat or cold can stress the cable components over time through thermal expansion and contraction. Copper wires can fatigue and break, while plastic cable jackets may develop tiny cracks.


Even larger fluctuations, like what might happen near an exterior wall or steam pipe, accelerate this process. The more the temperature swings, the shorter the useful life of the cable. That's why we recommend checking cable runs in temperature-variable areas most frequently.

Proper Ventilation is Key


To minimize temperature stress, it's important to provide adequate ventilation and climate control around network closets and cable pathways. This prevents areas from overheating in the summer or getting too cold in the winter.


Make sure wiring closets have fans or HVAC vents to flow cooler air. Use dust filters to prevent heat buildup from dust blocking airflow. And leave enough space around bundle cable runs so each one can dissipate heat. A little prevention goes a long way here.

Watch Out for Humidity Too


While temperature fluctuations cause physical stress, excess humidity has its own damaging effects over time. High humidity levels accelerate the corrosion of copper conductors inside cables. This can lead to intermittent or complete cable failures if left unchecked.


Low humidity on the other hand makes plastic cable jackets more brittle. Over long periods they can become susceptible to cracking or breaking if jarred or bent during installation. Proper humidity monitoring and control is needed wherever cables are located.

Dust, Dirt, and Other Airborne Nasties


We've all seen those thick layers of dust that accumulate inside wiring closets or under desks after a few years. Turns out dust isn't just visually unappealing - it's bad for structured cabling too. Dust clogs cable pathways, especially in high-traffic areas, which prevents proper airflow needed for cooling fiber optic cable installations.


More worrying are the various airborne contaminants that seem to find their way into every building. Things like VOCs from cleaning products or other airborne chemicals accelerate corrosion and degrade the optical signal quality inside fiber cables over time if the area isn't properly filtered. This is a serious concern for professionals responsible for maintaining and protecting major fiber optic cable installation infrastructures in busy facilities like those throughout the San Francisco Bay Area.

Regular Cleaning is a Must


To counteract these issues, we recommend regular cleaning inside wiring closets and under workspaces at least twice a year. Use compressed air and vacuums specifically designed for electronics to remove dust safely without damaging connectors.


Change air filters for the closet HVAC units on the recommended schedule too. Consider higher MERV-rated filters to capture smaller particles in areas with heavier contaminant potential. A little prevention here cleans up your cabling infrastructure.

Beware of Water Woes


No discussion of environmental hazards is complete without mention of the dreaded water damage. While indoor cabling has some protection, exterior-run cables or those located near plumbing lines inside face a higher risk. Even brief exposure to water can lead to corrosion inside conductors or bonded connections over time.


Fiber optic cable jackets may also develop microfractures from swelling and drying cycles after water contact. And of course, standing water creates ideal conditions for mold growth which releases more airborne particulates and chemicals.


Proper Protection Pays Off


The best defenses are sealed cable pathways, utilizing cable pans and sealant around penetrations to keep water out. Enclose outdoor runs in grounded metallic conduit for dual shielding. In high-risk spots near plumbing, consider additional overflow pans or leak detection alarms. An ounce of prevention is truly worth a pound of cure when it comes to curbing water woes.


It's also important to inspect cable pathways regularly for any deterioration or damage that could compromise seal integrity over time. Harsh outdoor environments and corrosive indoor conditions may accelerate the aging of seals, conduit connections, and other protective hardware. Caught early, minor issues are usually an easy and affordable fix. Left unaddressed, they could open pathways for contaminants and lead to costly repairs down the road. That's why organizations servicing Bay Area facilities should establish routine inspection and preventative maintenance programs for their telecommunications infrastructure. Annual reviews with a skilled cabling specialist can identify deteriorated protection elements before failures occur. A proactive approach to maintenance ensures critical cabling assets remain fully shielded from environmental threats and continue serving the organization's needs reliability for many years to come.
