FAQ Cabling

Overcoming the 300-Foot Limit: Standard copper Cat6 cables have a strict
physical limitation—they cannot transmit data reliably past 328 feet (100 meters).
For massive New Jersey warehouses, multi-acre logistics yards, or multi-floor
corporate offices, copper simply cannot reach the distance.

Speed of Light Performance: Fiber optics use light waves traveling through
flexible glass strands to transmit data. This allows for virtually infinite bandwidth
capacity over distances stretching across several miles with zero signal
degradation, making it the essential backbone for modern AI camera loops and
high-density data networks.

100% Immunity to Electrical Interference: Copper wires act as antennas,
picking up electromagnetic interference (EMI) from heavy industrial machinery,
high-voltage electrical panels, and fluorescent ballasts. Because fiber optics
transmit light rather than electricity, they are completely immune to EMI, cross-
talk, and lightning surges.

Multi-Mode Fiber (OM3/OM4/OM5): This infrastructure uses a wider glass core
and is designed for high-capacity, high-speed data transmission over relatively
short distances—typically inside a single building (up to 1,000 to 1,800 feet). It is
perfect for linking a central server room to different floor data closets or server
racks.

Single-Mode Fiber (OS2): This features an incredibly thin glass core that allows
a single laser path to travel for miles without losing strength. It is the gold
standard for long-distance perimeter camera runs, sprawling distribution centers,
and linking separate buildings in an industrial park complex.

Custom Assessment: Comtex engineers your system using the exact
combination required to balance cost, performance, and future scalability.

In-House Fusion Splicing Specialists: Fiber optic glass strands are thinner than a human
hair. Connecting them requires extreme precision. Comtex utilizes state-of-the-art, in-
house core-alignment fusion splicers. Our internal technicians physically weld the glass
fibers together using an electric arc, ensuring microscopic precision.

No Subcontractors: We never outsource our fiber work to third parties. By keeping our
fiber terminations entirely in-house, we guarantee perfect quality control, maximum
physical durability, and immediate accountability.

Eliminating Network Chokepoints: If you have 50 AI security cameras, 100 IP
office phones, and dozens of tenant computers all running simultaneously,
pushing all that data down standard cables will choke your network.

The High-Speed Highway: Comtex installs a central Fiber Backbone that
connects your main server room (MDF) directly to smaller intermediate data
closets (IDFs) distributed throughout your property. This creates a multi-gigabit
(10Gb, 40Gb, or 100Gb) highway that keeps your entire facility operating at peak
velocity with zero data bottlenecks.

Emergency Diagnostics and Repair: Yes. If a construction crew accidentally
cuts an underground fiber line, or if a warehouse forklift damages an exposed
distribution box, our local team can dispatch quickly with our diagnostic OTDR
meters. We can pinpoint the exact footage where the glass is broken inside the
wall or conduit, pull back the damaged section, and perform emergency fusion
splicing to restore your phones, cameras, and internet access immediately.

The 328-Foot Rule: For standard IP cameras running over copper Cat6, the hard limit is
328 feet (100 meters) from the nearest network switch. Pushing a copper cable past this
distance causes severe voltage drops and data packet loss, leading to dropped video feeds
or cameras that randomly reboot at night when their infrared illuminators click on.

Beyond the Limit: If your camera is at a far perimeter gate or a distant warehouse bay,
Comtex resolves this by deploying multi-strand fiber optics (which can run for miles)
or installing dedicated, hardened PoE extenders to safely bridge the gap.

Severe Life-Safety Code Risks: Access control sits at the intersection of security and
fire safety. If an amateur wires a magnetic lock directly to a power supply without
integrating it into the building’s life-safety infrastructure, the door will stay locked during
a fire, trapping employees inside.

Certified Fire Panel Integration: As licensed NY and NJ security professionals,
Comtex ensures all lock wiring routes through a dedicated fire alarm relay. If the
building’s fire panel triggers, power drops to the locks instantaneously and
mechanically, ensuring compliance with local building inspectors and life-safety codes.

HD-Over-Coax Retrofits: Yes. If your facility has an older analog system with miles of
heavy coaxial cable buried behind walls, ripping it out can be prohibitively expensive.

Cost-Effective Upgrades: We can deploy specialized EoC (Ethernet-over-Coax)
converters. This allows us to transmit full digital, high-definition IP video and PoE
power over your existing legacy coaxial cables. You get the power of modern Avigilon
AI analytics and crisp imaging without the massive capital expense of a total building
rewire.

Efficient Single-Drop Pass-Through: In most modern office setups, no. Most
commercial IP phones feature a built-in internal network switch. Comtex can pull a single
high-quality Cat6 line to the workstation drop. The cable plugs directly into the back of
your IP phone, and a secondary short patch cord routes from the phone directly into the
employee’s computer.

Halving Your Infrastructure Costs: This smart architecture delivers crystal-clear HD
voice and full network speeds to the computer while saving you thousands of dollars in
raw material and labor costs by avoiding duplicate cable runs.

Physical & Logical Separation: If a massive file is being downloaded or a large
database backup is running on a corporate computer, it can easily hog the network
bandwidth. On an unmanaged system, this causes your business phone calls to cut out,
crackle, or drop entirely.

Voice VLAN Configuration: When Comtex installs your data network and phone
cabling, we configure your network switches with a dedicated Voice VLAN (Virtual
Local Area Network). This mathematically isolates your phone traffic from your
computer traffic and applies strict QoS (Quality of Service) rules. Your voice data is
always given top priority on the wire, ensuring perfect call clarity even during heavy
network utilization.

A Clean Executive Presentation: Yes. We ensure that the employee workspace looks
immaculate. We install professional, flush-mounted wall faceplates, surface-mount boxes,
or modular furniture bezels that match your office decor. Every single port is clearly
stamped and labeled with a unique alphanumeric ID that maps directly back to the master
patch panel in the server room, making future IT additions or troubleshooting simple.
