Fiber-to-the-home (FTTH) is a method of providing high-speed Internet, television and telephone services using fiber-optic cables. These cables are made up of thin strands of glass or plastic that transmit data through light waves. Choosing the right fiber optic cable is critical to building a reliable and efficient FTTH network. In this blog, we will discuss the factors that should be considered when selecting fiber optic cable for an FTTH network.

Fiber Type : There are two types of fiber optic cables: single-mode and multimode. Single-mode fiber is used for long-distance communications because it allows for higher bandwidth and longer transmission distances. Multimode fiber is used for short distances because it has a larger core diameter and can transmit multiple signals at the same time. For FTTH networks, single-mode fiber is preferred because it can transmit data over longer distances and at higher speeds.

Fiber optic cables come in two main configurations: indoor and outdoor fiber optic cables. When choosing a cable, consider where it will be installed and what conditions it will be exposed to. Outdoor is available in GYXTW models. ADSS, GYTA/GYTS, GYTC8S, Mini ADSS. mainly used for duct and roadside suspension installations. From the building to the inside of the customer’s home, usually use FTTH Drop fiber optic cable. drop fiber optic cable is divided into three wire outdoor drop fiber optic cable and two wire indoor drop fiber optic cable.

Cable jacket: The cable jacket is the outermost layer of the fiber optic cable and is responsible for protecting the cable from environmental factors such as moisture, heat and abrasion. When selecting a cable jacket, consider the installation environment and the level of protection required. Common cable jacket types include polyethylene (PE), polyvinyl chloride (PVC), and low smoke zero halogen (LSZH).

Fiber Count Fiber count refers to the number of fibers in the cable. For FTTH networks, a fiber count of 1-12 fibers is usually sufficient. However, it is always a good idea to plan for future expansion by choosing a cable with a higher fiber count.

Connector Types Connectors are used to terminate fiber optic cables and connect them to other devices. Common connector types include SC, LC and ST. When choosing a connector type, consider the equipment that will be used and the compatibility required. For data centers, most use MPOs.

In summary, choosing the right fiber optic cable is critical to building a reliable and efficient FTTH network. When selecting fiber optic cable, consider the type of fiber, cable construction, cable jacket, number of fibers and connector type. By considering these factors, you can ensure that your FTTH network will stand up to the test.
