Fiber optic cables are widely used in modern, gradually replace of copper cables.

Key Specifications Of Fiber Optic Cables

·Transmission rate of 100 Mbps;
·Cable length of 2 kilometers or more;
·Not affected by electrical interference;
·Supports voice, video, and data;
·Provides the most secure media;
·Commonly used in backbones between buildings and Token Ring networks;
·Specifications for fiber include the IEEE's 10BaseFL (Ethernet) and ANSI's FDDI or Fiber Distributed Data Interface (Token Ring).

Depending on the number of fibers and how and where it will be installed, bulk fiber optic cables come in lots of different types. Choose cable carefully as the choice will affect how easy it is to install, splice or terminate and, most important, what it will cost! Such as tight buffered fiber cable and loose tube cable. Loose tube cable majority used in outside-plant installations, while tight-buffered cable primarily used inside buildings.

Tight Buffered Cable

Tight buffered (coated with a 900 micron buffer over the primary buffer coating) with Kevlar (aramid fiber) strength members and jacketed for indoor use. The jacket is usually 3mm (1/8 in.) diameter. Zipcord is simply two of these joined with a thin web. It's used mostly for patch cord and backplane applications.

Single-mode tight-buffered cables are used as pigtails, patch cords or jumpers to terminate loose-tube cables directly into opto-electronic transmitters, receivers and other active and passive components. Multimode tight-buffered cables also are available and are used primarily for alternative routing and handling flexibility and ease within buildings.

Distribution Cables

Distribution Cables contain several tight-buffered fibers bundled under the same jacket with Kevlar strength members and sometimes fiberglass rod reinforcement to stiffen the cable and prevent kinking. These cables are small in size, and used for short, dry conduit runs, riser and plenum applications. The fibers are double buffered and can be directly terminated, but because their fibers are not individually reinforced, these cables need to be broken out with a "breakout box" or terminated inside a patch panel or junction box. They can be multimode distribution indoor cable, single mode plenum distribution indoor cable, multimode plenum distribution indoor cable, waterproof cables, etc.

Loose Tube Cable

In a loose-tube cable design, color-coded plastic buffer tubes house and protect optical fibers. A gel filling compound impedes water penetration. Excess fiber length (relative to buffer tube length) insulates fibers from stresses of installation and environmental loading. Buffer tubes are stranded around a dielectric or steel central member, which serves as an anti-buckling element. The cable core, typically surrounded by aramid yarn, is the primary tensile strength member. The outer polyethylene jacket is extruded over the core. If armoring is required, a corrugated steel tape is formed around a single jacketed cable with an additional jacket extruded over the armor.

FiberStore covers a wide production line of bulk fiber optic cable, from common bare fiber, waterproof cables to special fiber cables for specific applications. Flexible or rigid cables of copper or aluminium, with a complete range of polymers and protectors, always developed under the most stringent international standards.
