FTTA: High-Performance Solution for Integrated Optical Fiber and 5G Networks

There is a huge demand for high-speed data transfers in today’s mobile telecommunications networks. FTTA (Fiber-to-the-Antenna) is an essential element of 5G networks and ensures reliable, robust, and future-proof installation, improves user experience and reduces costs. This article helps you to understand FTTA.

What is FTTA?

FTTA is a broadband network architecture to connect the building baseband unit (BBU) to the remote radio unit (RRU) at the top of the tower by using optical fibers to replace all or part of the coaxial network. FTTA can reduce the loss of signal power. And up to 20km's maximum transmission distance helps realize centralized placement of base stations (BS) in lower-cost telecommunication rooms and more flexible and modularized network planning.

FTTA Solution

FTTA solution reduces installation time and saves the cost of installation and maintenance. FTTA solution includes outdoor optic fibers, PDLC outdoor waterproof patch cords, terminal boxes, etc.

Benefits of FTTA

Perhaps the most benefit of FTTA stems from the physical content of the cable itself. The smaller diameter and lighter weight allow many fiber optic cables to occupy the same amount of space as a single coax cable. Because cellular towers are naturally subject to the elements, the physical size and properties of optical cabling are much less susceptible to damage from gusts of wind.

Other benefits of FTTA relate to the shift from analog to digital. Due to signal losses, the coax cable limited the distance between the antenna and the base station to as low as around 100m. Optical cabling can span up to 20 km with minimal losses.

FTTA provides improved energy consumption and signal integrity. Tower amplifiers are no longer required to combat the inherent noise floor of extended coax runs. The cooling of power amplifiers through air conditioning in a traditional base unit is replaced by ambient air cooling of the RRH, which significantly reduces the electrical power consumption of the system.

FTTA also provides flexible deployment, reduced complexity, saves installation time and space on the tower, lower investment, and high reliability.

Typical FTTA Scenario

Fiber optic networks aim to perform high-speed, error-free data transmission. Adequate testing during each phase of the network deployment guarantees that products meet specifications. It minimizes costly and time-consuming troubleshooting efforts, including locating dirty/damaged connectors, questionable splices, and other faulty components before they disrupt service.

One of the most crucial factors in ensuring proper transmission is controlling power loss in the network against the link loss-budget specifications from the network design recommendation, which establishes a total end-to-end loss budget with sufficient margin while reducing back reflection to a minimum.

What is the Future of FTTA?

Consumer demand and technological advancement will continue to challenge the broadband infrastructure and necessitate more innovation. As incremental improvements such as active antennas integrated with the RRH to eliminate the need for all coax, small cell technology, and tower construction continues to evolve, it is safe to assume the future of FTTA may hold a few more surprises.

5G network provides speeds up to 100 times faster than 4G, which requires more small cell sites/DAS and improvements in conventional antenna tower bandwidth. Fiber optics will continue to provide the lifeblood to this ever-evolving network because only fiber can support the backhaul of these small cell sites produced by this intense proliferation of traffic.

Conclusion

FTTA is an innovative, flexible, and future-oriented way to install the network. It secures your network connectivity today and in the future.

スキーアスロン

冬といえば、やっぱり冬季競技！ ということで、CATVで男子50kmクロスカントリーを観戦中です。少し前までは「距離」と呼ばれていた、いわば雪上スタコラ競争。

このクロスカントリーには3種類の滑り方があるそうで、

・クラシカル（昔ながらの歩くような滑り方） ・フリー（スケーティングのような滑り方） ・スキーアスロン（前半はクラシカル、後半はフリー）

と、なかなかバリエーション豊か。

それにしても、「スキーアスロン」なんて名前を初めて聞いたときは、「どんな競技や？」と思いましたよ。だって、トライアスロンを連想しません？ 泳いで、自転車こいで、フルマラソンを走るあの過酷な競技。

いっそのこと、スキーアスロンもこう進化させてみてはどうでしょう？

クラシカルで滑って、フリーで滑って、最後は海パン一丁になり、氷の張った池を泳ぐ……！

これぞ真の冬季競技（凍ﾀﾋ不可避）

New solar-sensors not getting much input (it's nighttime). Haha just-kidding. Wait - should I plug in a root for the ground?

Perry; a French sounding last name... but did you know architecture/Eiffel-Tower might not encapsulate contemporary-French culture? Computers have been around since as early as the 60's, and if you count abacuses, then one could argue "high-brow" society is organized around machines that think! Computer-architecture is the study of how electrons are passed around within a "thinking-machine."

I don't know if it's weird to lean into the nomenclature of your name (it's totally lame), but alas.. I don't know. It kinda fits😂 Moreover, the "inputs" I added to my Arduino (see slide 1) are solar-powered, and totally real😎

Also, the "Beagle-Bone" looks pretty legit. It sells for $100.00, and has an architecture that supports the lan/cat-v composition!

High-Performance Fiber Optic Cables for the FTTH Access Network Application

With the continuous development of FTTH (Fiber-to-the-Home) network construction, there will be more and more new varieties of fiber optic cables for the FTTH access network application. This article will discuss the three types of fiber optic cables for FTTH in detail.

Fiber Optic Cables for FTTH Access Network

FTTH is an access network architecture that allows deploying xPON technology to provide high speeds of Internet access downstream (from the network to the end-user) and upstream (from the user to the network) over optical fiber from the operator’s switching equipment to an individual home. The main fiber optic cables implemented to build up the FTTH access network are the FTTH feeder cable, FTTH distribution cable, and FTTH drop cable.

FTTH Feeder Cable

FTTH feeder cable, such as stranded loose tube light-armored cable connects the central office/hut to the fiber distribution hub (FDH). It is ideal for duct and aerial installations. This cable has good mechanical and temperature performance, high hydrolysis resistance, high strength loose tube, good crush resistance and flexibility, high tensile strength ensured by steel wire, and good moisture-proof ensured by PSP (steel tape).

Stranded loose tube light-armored cable construction is that 250um fibers are positioned in a loose tube which is made of high modulus plastic and filled with a water-resistant filling compound; A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member; Tubes are stranded around the strength member into a compact and circular cable core; The PSP is longitudinally applied over the cable core which is filled with the filling compound to protect it from water ingress; The cable is completed with a PE sheath.

FTTH Distribution Cable

FTTH distribution cable connects the FDH to the fiber access termination (FAT). FTTH distribution cable, such as indoor distribution cable uses φ900um tight buffer fibers as an optical communication medium and aramid yarn strength member. It is compliant with a PVC or LSZH jacket. Generally, FTTH distribution cable is available in fiber counts ranging from 2 to 144 fibers. It has excellent stripping performance of tight buffer fiber, good tensile strength, and small size. FTTH distribution cable is used in indoor /outdoor and backbone cable distribution in building applications.

FTTH Drop Cable

FTTH drop cable is used between the fiber terminal and the building or home. It is ideal for aerial, direct buried, and ducted installations. FTTH drop cable has good crush resistance ensured by parallel strength member, good tensile strength ensured by single steel wire, low smoke, small diameter, zero halogen sheath, simple structure, lightweight, and high practicability.

FTTH drop cable construction is that the optical fiber unit is positioned in the center. Two parallel steel wire strength members are placed at the two sides; A steel wire as the additional strength member is also applied. The cable is completed with an LSZH sheath.

Things to Consider When Choosing Fiber Optic Cables for FTTH Access Network

When choosing the three fiber optic cables for the FTTH access network, there are some general elements that you should pay attention to that influence the method of cable deployment.

Type of FTTH Architecture: The FTTH architecture implemented will influence the data rate and the optical power budget, which will affect the choice of fiber optic cable for the FTTH access network.

Fiber Type of Existing Network: If an existing network is expanded, you must add hardware that can integrate seamlessly with the existing infrastructure.

Installation Environment: No matter the indoor or outdoor applications, there are always different environments where the cable will be installed. For instance, in rugged spaces where your cable may suffer damage, such as basements or in conduits sharing space with electrical or other wirings, you may choose a rugged sheathed cable that is flexible and crush resistant.

Conclusion

FTTH allows a fiber optic cable to be laid from the provider’s equipment directly to the user’s home. Choosing the correct fiber optic cables for FTTH access networks will directly affect network reliability, operational flexibility, and the economics of FTTH deployment.
