With the rapid development of fiber optic communication technology, indoor and outdoor fiber optic cables are popularly used for varied applications in diversified industries. A fiber optic patch cord supplier provide fiber optic cables with various structures to suit different applications.

Outdoor fiber optic cables

Outdoor fiber optic cable is typically designed to operate safely in complex outdoor environment, often influenced by changes. These cables usually have loose buffer design, while strengthen member in the middle of the whole cable. There are loose tubes surrounding central strength member carrying waterproof gel filled and whole cable materials to make whole cable resist of water.These cables have rugged structures to resist ultra-violet light and temperature fluctuations. The most common types of outdoor fiber optic cables are GYTS, GYTA, GYXTW, GYTA53, GYTY53 and GYTC8S. These cables are designed to withstand demanding outdoor conditions due to changes in environment as well as mechanical forces. They can be often found strung along telephone poles or installed inside an underground duct.  

• For aerial and duct applications, GYTS, GYTA and GYXTW are used.
• GYTA53 and GYTY53 are used for direct buried
• GYTC8S the figure 8 outdoor fiber optic cable is used mainly for aerial.

When you are buying outdoor fiber optic cable, you need to consider many different factors such as specific environment, ultraviolet etc.

Indoor fiber optic cables

Indoor fiber optic cables are installed between and inside buildings. The common types of indoor fiber optic cables are GJFJV, GJFJZY, GJFJBV, GJFJBZY, GJFDBV and GJFDBZY. These cables experience lesser temperature and mechanical stress than outdoor used fiber cables. They are usually tight buffer design. They are typically consisting of the FRP which is non-metallic strengthen member, the tight buffer optical fiber and the Kevlarand the cable outer jacket.LSZH or other RoHS compliant PVC materials are generally used to make cable jacket. It is essential for indoor cables have flame retardant jacket as they are used inside the building.

Single mode indoor fiber optic cables are installed between the buildings where the distance is more than hundred meters. These cables might be deployed in a duct or cable tray. It is essential to consider fire prevention requirements while deploying them. Multimode indoor fiber optic cables are used for shorter distance connections.

There has been significant increase in the demand for a fiber-optic cable suitable for indoor and outdoor environments meeting harsh requirements of indoor and outdoor applications i.e. fire prevention, resistance to cold and moisture. A fiber optic patch cord supplier can help you in finding the right cable to suit your applications, while ensuring safety and other factors.
