Cable Structure and Components

Connector Type: SC/UPC

The SC (Subscriber Connector) is a widely used push-pull connector known for its durability and low insertion loss.

UPC (Ultra Physical Contact) polishing ensures low return loss (>50dB), making it ideal for high-speed data transmission.

Fiber Type: G.657.A2 Single-Mode Fiber

G.657.A2 fibers are optimized for bend-insensitive performance, crucial for FTTH deployments.

Compliant with ITU-T G.657 standards, offering superior resistance to macro- and micro-bending losses.

Cable Jacket: LSZH/TPU, 3.0mm Diameter

LSZH (Low Smoke Zero Halogen) material enhances safety by reducing toxic emissions in case of fire.

TPU (Thermoplastic Polyurethane) provides flexibility, abrasion resistance, and UV stability.

The 3.0mm outer diameter ensures a compact yet robust design for easy installation in tight spaces.
