FTTX Fiber Optic G657A1 Self Supporting Aerial 1 2 4 Core Outdoor FTTH Drop Cable
Feature:
1.Soft and bendable, easy to deploy and maintenance.
2.Smaller diameter, Light weight, and high practicability.
3.Fiber reinforced plastic as the strength member ensures excellent anti-electromagnetic performance.
4.Environmental protection- Low smoke, zero halogen and flame retardant sheath.
Applications:
1. Used in access network or as access cable from outdoor to indoor in customer premises network;
2. Used as access building cable in premises distribution system, especially used in indoor or outdoor
