Product Description
GYFTY Outdoor Fiber Optic Cable
APPLICATION:
1.Laying method: Duct
2.Suitable for long-distance trunk and LAN communication in high-voltage area or access to telecom network. Especially for power transmission system, excessive thunder areas and high electromagnetic interference.
3.Fiber type: Single-mode/Multimode
CHARACTERISTICS:
1.Non-metallic structure providing excellent anti-electromagnetism,anti-thunder and anti-static performance.
2.Accurate fiber excess length ensures good mechanical and temperature performance.
3.Specially designed compact structure is good at preventing loose tubes from shrinking.
4.High strength loose tube that is hydrolysis resistant and special tube filling compound ensure a citical protection of fiber.
