Future-Proofing FTTH Cabling Solution for Indoor & Outdoor Application

FTTH (fiber to the home) has replaced the existing copper cables in appliances such as telephone wires by bringing about a unique system of delivering optical fiber to the homes and offices directly from the switching equipment of the operator. Their network is spread between both outdoor and indoor sections of the house, and hence, they require various different types of fiber optic cables. This tutorial will recommend some FTTH fiber optic cables for your reference.

FTTH Fiber Optic Cable to Individual Homes

Fiber to the home (FTTH), also called "fiber to the premises" (FTTP), is the installation and use of optical fiber all the way to individual buildings such as single family units (SFUs), multidwelling units (MDUs), and businesses to provide high-speed broadband access. FTTH network is easier to maintain and delivers 100 times more bandwidth than coaxial, wireless, or copper networks. It has virtually unlimited capacity to bring telephone, Internet, digital television and other great services to subscribers—with high quality and reliability!

Fiber Optic Cable is proved to deliver bundled data, voice and video services to the home more efficiently and securely versus traditional copper transport mediums. We are all aware of slow dial-up frustrations, DSL outages, and coax cable issues (Broadband Cable TV). Once fiber optic is deployed as an end to end solution, all these inherent problems associated with copper /coax based transport facilities will eventually disappear.

Options for FTTH Cabling Solution

FTTH networks are installed in many areas covering indoor section, outdoor section, as well as the transition in between. To fulfill the cabling requirements from different areas, different types of fiber optic cables are well developed.

Indoor Cables

FTTH indoor cable is used inside a building or house to connect the FTTH user end equipment. Its fiber count typically is 1, 2 or 4 optical strands commonly combined with two non-metal enhanced FRP/Metal/KFRP which can provide sufficient tensile strength and good resistance to lateral crushing to protect the fiber inside. In addition, its outer sheath universally consists with LSZH material with good flame-retardance in white or black. Its simple convenient structure makes it perfect for indoor cabling.

FTTH indoor cables are characterized by:

 Special low-bend-sensitivity fiber provides high bandwidth and excellent communication transmission property.  Two parallel strength members ensure good performance of crush resistance to protect the fiber.  Simple structure, light weight and high practicability.  Novel flute design, easily strip and splice, simplify the installation and maintenance.

Drop Cable

FTTH drop cable connects Network Access Point (NAP) to the subscriber premises. Drop cables are designed with attributes such as flexibility, less weight, smaller diameter, ease of fiber access and termination. Their structure as well as their performance is optimized to be able to work with various FTTH applications. Drop cables will contain only 1 or 2 fibers for the connecting circuitry and possibly additional fibers for backup or for other network architecture reasons. This kind of wire is available in less fiber count and provides the only link to the subscriber, with no network diversity. Drop cables can be divided into 3 types: direct buried cable, blown fiber cable and aerial cable.

 Durable and flame retardant LSZH sheath, low smoke zero halogen  Single steel wire as the additional strength number ensures good performance of tensile strength  Two parallel FRP strength members ensure good performance of anti-electromagnetic and crush resistance  High speed optical routes in building

Distribution Cable

Fiber distribution cable is ideal for applications requiring a single termination point with multiple fibers. It has a tight buffered design so it can be installed in intra-building backbone and inter-building campus locations without expensive transitions between cable types. These highly popular cables are designed for both indoor/outdoor applications. Distribution cables are available in plenum, riser, unitized & non-unitized constructions which fit a wide array of general purpose installations. Their small bend radius and 900µm tight-buffered fibers allow for fast installations and easy terminations.

 900µm Tight Buffered Fibers: fast and robust field termination  Single-Unit Designs: provide space savings & easier installations  All-Dielectric Designs: eliminate the need for grounding  Interlocking Armor: removes the need for conduit

Notices for Choosing FTTH Fiber Optic Cable

A number of factors should be taken into consideration when making final decision.

Fiber Type of Existing Network

If an existing network is expanded, the optical fiber in the new network segments must be compatible with the fiber in the existing network.

Expected Lifetime

FTTH networks are designed with a lifespan of at least 30 years. So it is imperative that investments to the FTTH infrastructure are suitable for future needs. Changes to the choice of fiber during the expected lifespan of the FTTH network are not a realistic option.

Installation

No matter indoor or outdoor application, there always are different environments that your fiber will be installed. For example, in rugged spaces that your fiber may suffer damage, such as basements or in conduits sharing space with electrical or other wiring, you may choose a rugged sheathed cable that is flexible and crush resistant. There are many variables that will determine which types of fiber are most appropriate in the different parts of the installation. In most cases, one type will not fit all.

Future Trend and Advantages of Fiber to the Home (FTTH)

For the current home network users, FTTH is a very ideal network structure. When you have video chats and online conversations with family and friends, this kind of network can transmit a lot of data through cabling so as to ensure smooth video chatting, which turns out to be very convenient and reliable.

Some experts point out that FTTH is the only network meeting the needs of home broadband within ten years. As we all know, fiber to the home is a passive network which needs no active components, thus the cost of network maintenance and installation has been greatly reduced. But this is the main reason for popularity of FTTH? What are the real advantages of it?

Firstly, fiber optic cables are safer, since they will not be easily corroded by lightning or rain, or cause leakage. Because of its high stability, optical fibers gradually replace copper into the network infrastructure, promoting the development and progress of technology.

Secondly, it can provide unlimited bandwidth. With the development of technology, video applications such as video streaming, IPTV, high-quality video conferencing, smart home technology, IP video home surveillance, and games are gradually permeating into people's daily lives, which lead to further expansion of people’s demand for bandwidth. At present, only the optical network can assume responsibility.

Thirdly, FTTH network construction can bring real profits for consumers. According to FTTH Council statistics, FTTH network benefits each household with actual profit of almost $5000. In addition, the construction of FTTH network makes it more convenient for people to use the Internet, drawing near to "global village". Even in remote rural areas, people can also make trade contacts globally.

Conclusion

Now, FTTH technology has entered tens of thousands of households, and it is an inevitable trend of network technology development. Currently, the deployment of FTTH network has been promoted as a national strategy. The construction of optical networks will continue to improve for a long time in the future. And fiber optic cable, as a fast and cost-effective solution will enjoy widespread popularity instead of copper wires. So, are you ready to embrace the benefits of FTTH network?
