300μm Tight Buffered Fiber Optical Cable is designed to provide reliable performance in indoor environments, particularly in LANs, data centers, telecommunications, and FTTH networks. The cable consists of individual optical fibers, each protected by a 300μm tight buffer, typically made from polycarbonate or a similar material, which provides mechanical protection to the fiber.

Key Features:

• Fiber Construction: The optical fibers, typically either single-mode or multi-mode, are each coated with a 300μm tight buffer. This buffer serves to safeguard the fiber and prevent damage during installation and handling.
• Strength Member: For added durability and strength, the cable incorporates a strength member made of materials like Aramid yarn or glass fibers. These members help the cable maintain its shape and prevent stretching or breakage during use.
• Sheath Material: The outer jacket of the cable is typically made from PVC (Polyvinyl Chloride) or LSZH (Low Smoke Zero Halogen) material, providing flame retardant properties to enhance safety in fire-prone environments. LSZH cables are particularly suitable for indoor applications where low smoke emission is crucial in case of fire.
• Cable Diameter: The overall diameter of the cable is typically between 3.0mm to 4.0mm, making it suitable for tight spaces, such as within walls, ceilings, or conduits.
• Water Resistance: Some versions of this cable can include water-blocking materials to provide additional protection against moisture and water ingress, which is essential for outdoor or semi-exposed environments.
• Temperature Range: The cable is designed to perform in a wide range of temperatures, typically from -20°C to +60°C during operation, and -40°C to +70°C for storage.

Applications:

• Indoor Use: Ideal for LAN networks, where space constraints and high-density installations are common.
• Data Centers: Often used for high-speed data transmission between equipment racks and for backbone wiring.
• Telecommunication: Suitable for FTTH (Fiber to the Home) or FTTP (Fiber to the Premises) deployments, providing high-performance connections to end-users.

Performance Characteristics:

• Bend Radius: The minimum bend radius is typically around 20mm for short-term bending, ensuring the fiber’s integrity is maintained during installation.
• Attenuation: The attenuation rate for single-mode fibers is typically ~0.35 dB/km, while multi-mode fibers may vary depending on the type.
• Insertion Loss: The cable typically features low insertion loss, generally less than 0.1 dB per connector.

Compliance:

• 300μm tight buffered fiber optical cable generally complies with RoHS (Restriction of Hazardous Substances) standards, ensuring that it is free from harmful materials. It is also typically certified under UL (Underwriters Laboratories) and has ISO 9001 certification, indicating quality control during manufacturing.

This cable type is ideal for scenarios where mechanical protection and ease of installation are essential, providing a reliable and durable solution for indoor fiber optic networks.
