Description
Composit Fiber Optic Overhead Ground Wire(OPGW) is a composite overhead optical ground wire that provides high capacity communication channels to service present and future needs.
SFPOC-LUXTM features high optical fiber count providing expanded communication capabilities.
SFPOC-LUXTM is custom designed to satisfy each customer＇s specified communication and groundwire requirements for short circuit current capacity, tensile strength, fiber count and fiber type while complying to ASTM, IEE or IEC International Standards.
Installation of SFPOC-LUXTM is straightforward utilizing standard OPGW hardware and equipment.
SFPOC provides with its product a comprehensive range of services, including type testing, OPGW hardware, installation supervision and training.
Optical Design Features
SFPOC-LUXTM provides the type and number of optial fibers needed to meet castomer＇s specific requirements while complying to ITU-T Standards.
SFPOC-LUXTM features optical fibers placed loosely in a hermetically sealed stainless steel tube containing a gel filling compound to form an optical unit.This tube provides protection to the optical fibers during installation and operation under severe enviroumental conditiond.
The optical fibers 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 together with one or more optical units.
The Aluminum-Clad Steel and Aluminum Alloy wires provide the mechanical strength to withstand installation and operating conditions, while achieving the conductivity needed to control temperature rise during short circuit fault conditions.
