GJYXFCH Cable is Self-supporting butterfly entry cable,which places the optical fiber in the center, place two parallel steel wires on both sides as reinforcing elements (or non-metallic FRP reinforcing parts), and add a reinforcing element on the outside to extrude a low-smoke. GJYXFCH Cable is Self-supporting butterfly entry cable,which places the optical fiber in the center, place two parallel steel wires on both sides as reinforcing elements (or non-metallic FRP reinforcing parts), and add a reinforcing element on the outside to extrude a low-smoke. 2 Core G657A2 GJYXFCH Butterfly Optical Cable for FTTH Indoor/Outdoor Use Technical Highlights 2/3/4 kM per plywood/wood drum against manufacturing defects (7*24 hours) (after 500 cycles) Aerial cable: ADSS, ASU, OPGW, Figure 8 cable FTTH drop cable: GJXFH, GJYXFCH Armored buried cable: GYTS. FTTH indoor cable because of Fiber Type Singlemode G. 657A has a much greater bandwidth to carry data and less susceptible to interference than common indoor fiber cables because flexibility of Singlemode G. 657A1 bendable characteristics. With small diameter, water-resistant, the non-metallic. Small diameter, light weight and strong practicability; 2. the structure is simple and reasonable, and has good compressive, tensile and anti-aging properties. The '8' groove design is easy to peel off the sheath and simplify installation and maintenance; 4. The name comes from the cross-section: a flat, wing-shaped profile with the optical fiber sitting in the center and two parallel strength members flanking it on either side. Featuring a durable construction with 3 steel wires for added strength, this low smoke halogen-free (LSHF) cable ensures safety and.
