Cabling & layer one

Step one: layer one

Cabling & Layer One is one of the first things you should take into consideration. It is for GDT.

Before starting an install, before sending an installer to your site, we pre-site survey and EF&I scope your layer one, structured cabling, and data center in order to know even the most minute details about your business and operation. We know what cabinets or racks are needed and the exact location of where they need to go. We know the type and location of all power sources and exactly how far cords and cables need to reach. We identify needed infrastructure and the overhead framework, racks, fiber trough and ducts required for fiber protection.

Our EF&I services help reduce risk and better your project’s outcome

As with all GDT professional services, our Layer One Team offers exceptional service and goes beyond the expected to accomplish your job as quickly as possible. We ensure that all necessary materials are on hand and available before the project start date and before we leave, we complete a quality audit. That audit ensures our installers have cleaned up your existing closets and confined spaces to not only provide a professional appearance, but also give you reliability and efficiency, scalability and manageability, and ease of tracing during challenge resolution.
