Stranded Loose Tube Optical Cable—GYFTY
Description
Optical fibers are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. The tubes (and fillers) are stranded around the central strength member to form a cable core. The core is covered by compound filling gel. Finally, an outer PE sheath is extruded.
Applications
This product can be used as outdoor transmission lines in core network (for example, long haul and relay lines between local telecommunication centers). It can also be used as outdoor distribution lines or feeder in access network.
Application Circumstances
Recommended: Duct, Aerial, Groove
Optical Fiber
Single mode optical fiber or multimode optical fiber shall be selected according to the needs of users
