Duplex Round Indoor Cable

Duplex round indoor fiber optic cable is a two-core fiber cable designed for bidirectional data transmission in indoor communication systems. With a compact round structure and tight-buffered fibers, it provides excellent flexibility, durability, and ease of installation.

This cable is widely used for patch cord manufacturing, equipment interconnection, and high-speed data transmission in data centers and enterprise networks.

What is Duplex Fiber Optic Cable?

A duplex fiber optic cable contains two optical fibers, allowing simultaneous transmission and reception of signals between devices. Duplex Communication

Each fiber carries signals in opposite directions, enabling efficient two-way communication, which is essential in modern networking systems.

Key Features

• 2 core (duplex) fiber structure
• Round cable design for easy routing
• 900μm tight-buffered fibers for protection
• Aramid yarn (Kevlar) strength member
• Excellent flexibility and tensile strength
• Jacket options: PVC / LSZH / OFNR / OFNP
• Suitable for SM (G652D / G657) and MM (OM1–OM5)

The tight-buffered structure and aramid yarn reinforcement provide durability and protection for indoor use

Cable Structure

Typical duplex round indoor cable includes:

• Optical fiber (250μm)
• 900μm tight buffer layer
• Aramid yarn reinforcement
• Outer round jacket

This structure ensures strong mechanical performance and stable signal transmission.

Applications

• Fiber optic patch cord manufacturing
• Equipment interconnection
• Data centers and server rooms
• Telecom and LAN networks
• Fiber distribution frames

Duplex cables are commonly used in Ethernet systems, switches, and servers where two-way communication is required.
