1. GYFY optical fiber Descreption:
The loose tubes are made of high modulus plastics (PBT) and filled
with a water resistant filling gel. Loose tubes are stranded around
non-metallic central strength member (FRP). The cable core wrapped
with a water blocking tape, and then aramid yarns or glass yarns
are applied over the cable core. Polyethylene (PE) is extruded as
inner sheath.
2. Structure:
♦ Central strength member: metal materials available
♦ Loose tube: PP or other materials available
♦ Water blocking materials for loose tube: water blocking yarn
available
♦ Water blocking materials for cable core: cable filling compound
available
3. Features:
♦ All section water blocking
♦ Anti-ultraviolet radiation
♦ Excellent transmission, mechanical and environmental performance
♦ All dielectric, anti-lightning, anti-electromagnetic interference
♦ Easy installation, easy maintenance
♦ Lifespan over 30 years
4. Application.
♦ Aerial installation
♦ Duct installation
♦ Backbone network and metro network
5. Installation
♦ Min. bend radius: installation 25D, operation 12.5D
♦ Temperature range: storage -40～+70℃, installation -30～+70℃,
operation -40～+70℃
6. performance
♦ Applicable to direct burial/aerial installation
♦ For flame retardant cable, outer sheath can be made of low-smoke
halogen-free (LSZH) material and the type is GYFTZ, for
anti-termite cable, additional nylon resin is extruded over outer
sheath and type is GYFY04
♦ Special cable structure can be designed and manufactured on
customer's request
