Frequently Asked Questions
Your Structured Cabling & Fiber Optics Questions — Answered
At Comnet Communications, we understand that infrastructure decisions require clarity. Whether you're managing a new construction project, upgrading legacy systems, or preparing a government facility for inspection, it’s important to work with a contractor who can provide clear, consistent answers.
Below are answers to some of the most common questions we receive about our network cabling, fiber optic, and low voltage services.
General Services
What types of facilities do you work with?
We serve a broad range of clients including commercial office buildings, federal and municipal agencies, schools and universities, healthcare facilities, military installations, and industrial campuses. Our work spans single-site projects to multi-building and multi-state rollouts.
Are you licensed and certified?
Yes. We hold active low voltage contractor licenses in California and Wyoming, and our lead technicians are BISCI Certified (ITS Technician – TE30 Certified, ID: 245922). All installations follow TIA/EIA-568A/B standards and applicable building codes.
What geographic areas do you serve?
We’re headquartered in Livermore, CO and provide services throughout Colorado, Wyoming, and California. We also complete projects in nearby states by request, including Arizona, Nevada, New Mexico, and beyond.
Do you work with general contractors or only directly with businesses?
Both. We frequently subcontract with general contractors on construction projects and also work directly with facility owners, IT managers, and operations teams.
Structured Cabling
What is structured cabling, and why is it important?
Structured cabling is the standardized infrastructure that supports voice, data, and video across a facility. It includes Ethernet cabling, fiber optics, patch panels, and network rooms. It enables fast, organized communication between all systems and devices, allowing for future scalability and reduced maintenance.
What types of cable do you install?
We install Cat5e, Cat6, and Cat6A copper cabling as well as single-mode and multi-mode fiber optic cable. We choose cable types based on your speed requirements, distance, building layout, and future upgrade plans.
How do you ensure cable performance after installation?
Every cable run is tested and certified using tools like Fluke testers and OTDRs. We document insertion loss, length, continuity, and other factors to ensure every cable is ready for service — with full reports provided.
Do you label and document cabling?
Yes. Every installation includes port labeling, cable routing documentation, and test results. We provide this in digital format (PDF), on CD, or via email for IT and compliance use.
Fiber Optic Services
What’s the difference between single-mode and multi-mode fiber?
Single-mode fiber is designed for long-distance, high-speed connections — often used between buildings or across large campuses. Multi-mode fiber is used for shorter runs within a building, such as between IDF rooms or to server racks.
Can you install fiber outside between buildings?
Yes. We install outdoor-rated OSP fiber in conduit, direct burial, or aerial configurations to connect buildings across campuses or sites. We ensure all transitions to indoor space comply with fire and code regulations.
Do you provide fiber splicing and termination?
Absolutely. We perform both fusion and mechanical splicing, and terminate fiber using SC, LC, or ST connectors depending on your hardware. All terminations are tested and labeled.
Can you test existing fiber that was installed by another company?
Yes. We provide third-party OTDR and power meter testing for new and existing fiber installations — whether installed by us or another contractor. This is often requested for warranty activation, compliance, or troubleshooting.
Network Rooms & Internet Cabling
Do you build MDF and IDF rooms?
Yes. We design and install Main Distribution Frame (MDF) and Intermediate Distribution Frame (IDF) rooms, including racks, patch panels, grounding, and ventilation planning. These are the nerve centers of your cabling infrastructure.
How do you handle ventilation and equipment heat in network rooms?
We assess heat loads and coordinate with HVAC contractors or your facilities team to ensure proper airflow, cabinet spacing, and cooling strategy for all network spaces.
Can you install internet cabling for workstations and wireless access points?
Yes. We install Ethernet drops for offices, access points, security devices, and VoIP phones. Each drop is labeled, tested, and routed to a central patch panel for easy management.
Do you handle cabling for Wi-Fi systems?
We install Cat6/Cat6A cabling to support ceiling-mounted wireless access points (WAPs), ensuring optimal placement, bandwidth, and power (PoE) compatibility.
Testing, Certification & Documentation
What kind of test results do you provide?
We deliver certified test results including OTDR traces for fiber and Fluke test results for copper. These include pass/fail results, loss measurements, cable IDs, and routing maps — formatted for digital storage and reporting.
Is testing included in the installation price?
Yes. For all full-scope installations, testing and documentation are included. For testing-only services (third-party certification), pricing is provided by strand or drop count.
Can I use your test results for compliance or closeout?
Absolutely. Our documentation is suitable for contractor closeouts, IT handovers, warranty activation, and government or industry audits.
Project Scheduling & Process
How long does a typical installation take?
Project timelines vary based on size and complexity. A small office may take 1–3 days. Large buildings or multi-floor systems may take several weeks. We provide a clear schedule after a site visit or plan review.
What do you need to begin a project?
We typically begin with a site walk, floor plan review, or construction drawings. From there, we provide a written quote, scope of work, and project timeline for approval.
Do you offer emergency or after-hours service?
Yes. While most installations are scheduled during regular business hours, we offer flexible scheduling for sensitive or time-critical work.
