FTTH 2 Cores Fiber Optic Indoor Drop Cable
Short Description:2 Cores Fiber Optic Indoor Drop Cable has simple structure, light weight and high tensile strength. Two parallel steel wires/FRP strength members ensure tensile strength and crush resistance.
The optical fiber unit for 2 Cores FTTH Indoor Drop Cable is located in the center of a butterfly flat construction. At the two sides, two parallel FRP strength members are installed. The cable is then sheathed with an LSZH sheath. The 2 Cores FTTH Indoor Drop Cable has a substantially higher data-carrying bandwidth and is less vulnerable to interference than standard indoor fiber lines. It’s simple to deploy and maintain because of its bendability, softness, water resistance, and tiny diameter. In addition, the non-metallic strength part may guard against lightning and electromagnetic interference. Access network cabling, end-user direct cabling and indoor cabling, are all possible with FTTH cables.

Fiber Optic vs. Copper
Question1: What’s the difference between G657A1 and G657A2 type cable?
Answer1: G652D/G657A1 fibers provide marginally lower loss transmission, which is better in facilitating long distance communication links (up to and greater than 100km).
However, G652D fibers have limited bend resistance.
G657A2 fiber has greater resistance to bending (macro bend) losses, and facilitating low-cost deployment techniques. G657A2 fibers are fully compatible with G652D fibers. The G657A2 fiber mode Field Diameter is 9.8µ[email protected] Splice losses are slightly higher when splicing the two different fibers together.
G657A2 fibers are used in advanced access cable network installation, where higher bend resistance is required for smaller cable jointing pits and also allows for cable and hardware miniaturization.
