Fiber Installations

Optical fiber plays a critical role in today’s communication networks – from telecommunications to CATV to data.
Global Access Networks is a major Installer and supplier of high quality optical fiber and fiber optic products. The fiber cables are manufactured using the advanced Plasma Activated Chemical Vapor – PVCD process. Because of the inherent advantages of the process, our fibers shows extremely refined Refractive Indexes profile control, excellent geometric performance and low attenuation.


This includes a complete line of  Optical Fiber cables  that produce highly accurate, reliable splices with minimal loss, Our manufactures provide cables and equipments that are designed using state-of-the-art technology decades of manufacturing experience and feedback from countless customer installations.
 
OFC CONSTRUCTION
Global Access Cable construction is generally installed using one of three methods: aerial, direct burial, or in conduit. This section provides some of our general guidelines for using these construction methods.


1. AERIAL/OVERHEAD CONSTRUCTION
Our Aerial cable is typically strung from pole-to-pole, or from building-to-pole. Two types of cable are available: self-supporting or lashed.
The self-supporting cable is designed with either a heavy duty central strength member, or in a figure eight configuration that has an external strength member that can be clamped. Lashed cable is similar to cable that can be direct buried and requires a "messenger support wire" to which the cable is affixed.
When using aerial cable, our engineers provide sufficient supporting utility poles in the route to minimize the effect of cable sag. This is caused by external forces such as wind and extreme temperature changes added to the weight of the cable.


2. UNDERGROUND/ DIRECT BURIAL CONSTRUCTION
Our Cable can be buried directly in soil using one of two general construction methods: open trench construction, or cable plow. In both instances, a cable rated for direct burial should be used. These cables are designed with a metallic armor sheath to prevent damage from rodents that may try to chew through the cable. The direct burial method is especially useful in rural and suburban locations. The non-paved portion of a rural road or highway right-of-way is a good candidate for this construction method. The route is carefully planned taking care to avoid other buried utilities (water, electrical, telephone, gas, etc.) and meeting environmental requirements.
