Single Mode GJXH FTTH Indoor Drop Cable G657A G652D 1 2 4 Core
Product Overview
The GJXH FTTH Indoor Drop Cable is constructed with one or two single-mode fibers (G.657A1). The cable features a dielectric strength member made of single-stranded steel wire and a LSZH outer jacket. Designed specifically for indoor installation, this cable is ideally suited for connections between dome closures and small dwelling units, warehouses, and independent villas.
Key Features
- Special low-bend-sensitivity fiber provides high bandwidth and excellent communication transmission properties
- Two parallel steel wire strength members ensure superior crush resistance to protect the fiber
- Simple structure, lightweight design, and high practicability
- Novel flute design for easy stripping and splicing, simplifying installation and maintenance
- Low smoke, zero halogen, and flame retardant sheath
Applications
- Ideal for FTTH (Fiber to the Home) applications
- Horizontal cabling installations
