3-Unit Figure-8 Self-supporting Micro Optical Cable (GYFC8A (3U))
Optical fibres are housed in 3 loose tubes that are made of high-modulus plastic and filled with tube filling compound. The tubes are stranded around the central strength member to form a cable core. The core is surrounded with water blocking yarns and armored with laminated aluminum tape. A steel wire is applied as the messenger. Finally, a figure-8 PE sheath is extruded. This type of cable is typically applicable to self-supporting aerial installation.
