G657A1 Overview:

The G657A1 Drop Cable Fiber Optic is a single-mode fiber optic cable designed for various applications, particularly in FTTH (Fiber to the Home) installations. It features a G657A1 single-mode fiber construction, which is optimized for efficient data transmission over long distances.

The LSZH (Low Smoke Zero Halogen) jacket material provides fire safety by minimizing smoke and toxic gas emissions in case of fire, making it suitable for indoor installations where safety is a concern.

This drop cable design enables easy accessibility to the fiber and simple installation directly to homes or buildings. It typically consists of optical fibers positioned in the center, surrounded by two parallel Fiber Reinforce Plastic (FRP) strength members for mechanical support. The cable is completed with an LSZH sheath for added protection and durability.

The G657A1 Drop Cable Fiber Optic is known for its reliability, high performance, and ease of installation, making it an ideal choice for FTTH deployments and other applications requiring dependable fiber optic connectivity.

Factory FTTH drop cable 1 fiber G652D G657A1 optic cable GJXH for indoor use FTTH indoor drop cable is constructed with two single mode fiber. The cable is protected by a dielectric strength member made of fiberglass reinforced plastic (FRP) and a LSZH outer jacket for use in FTTH & FTTx applications between the building’s main telecommunications room and the apartment / office consolidation point.
