Product Description

Steel Tube encased in an Aluminum Tube
Composit Fiber Optic Overhead Ground Wire(OPGW) is a composite overhead optical groundwire that provides high capacity communication channels to service present and future needs.

SFPOC-DUALTM is a compact OPGW design with excellent short circuit current capacity and mechanical strength.
The SFPOC-DUALTM construction consists of a sealed inner stainless steel tube encased in an aluminum sealed tube. This design is well suited for highly corrosive environments without requiring the use of anti-corrosive grease.

The dual tube design offers greater crush and mechanical protection to the fibers from environmental effects. Single wire layer designs allow for larger outer metallic wires, offering excellent lightning performance.

SFPOC provides with its products a comprehensive range of services, including OPGW hardware, installation supervision, type testing and training.


Optical Design Features
SFPOC-DUALTM provides the type and number of optical fibers needed to meet customer's specific requirements while complying to ITU-T Standards.
SFPOC-DUALTM features optical fibers placed loosely in a hermetically sealed stainless steel tube covered with aluminum layer containing a gel filling compound to form an optical unit.
The optical tibers have low signal attenuation and wide band width allowing for long distance, high capacity communication.
Optical fibers are free from crosstalk and are not subjected to electromagnetic interference and polarization. They provide secure high quality signal transmission.


Groundwire Design Features
Aluminum-Clad Steel and Aluminum Alloy wires are stranded around a central optical unit.
The Aluminum-Clad Steel wires and Aluminum Alloy wires provide the mechanical strength to withstand installation and operating condition, while achieving the conductivity needed to control temperature rise during short circuit fault conditions.
