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.

What Is Fiber Optic Cable?

Optical fiber cable is a type of communication cable. It uses one or more optical fibers in a protective covering to transmit information. We can use optical fiber cables alone or in groups to meet specific performance requirements. 

Fiber cables are mainly composed of optical fibers (glass fibers as thin as hair), plastic protective sleeves, and plastic sheath. There are no metals such as gold, silver, copper, aluminum, etc. inside the cable, and it generally has no recycling value.

Basic Structure

Fiber Optic Cable Types

1. According to different transmission performance, distance, and purpose, optical fiber cables can be divided into end user fiber cable, local telephone cable, long distance cable, and underwater fiber optic cable.

2. According to the types of optical fibers used, they can be divided into single mode fiber optic cable and multimode fiber optic cable.

3. According to the number of fiber cores inside, it can be divided into single core optical cable, dual core fiber cable, multi-fiber cable, etc.

4. According to the different configuration methods of reinforcement components, optical cables can be divided into central reinforcement optical cables, dispersed reinforcement optical cables, protective layer reinforcement optical cables, and comprehensive outer protective layer optical cables.

5. According to the different transmission conductor and medium conditions, optical cables can be divided into non-metallic fiber cable, ordinary optical cables, and comprehensive optical cables (mainly used for railway dedicated network communication lines).

6. According to different laying methods, optical cables can be divided into pipeline optical cables, underground fiber optic cable (direct burial fiber optic cable), aerial fiber optic cable, and submarine fiber optic cable

Optical Fiber Cables Limit

The Optical Fiber cables are mainly limited by two indicators: allowable tensile strength and flattening forces. See below:Cable typeAllowable tensile (N)Allowable tensile (N)Allowable flattening forces (N/100mm)Allowable flattening forces (N/100mm)Short termLong termShort termLong termDuct, non self-supporting aerial fiber optic cable15006001000300underground fiber optic cable3000100030001000Special direct burial fiber optic cable10000400050003000undersea fiber optic cable （20000N）200001000050003000submarine fiber optic cable（40000N）400002000080005000

Pre Terminated Fiber Cable Methods

The main methods include permanent connections, emergency connections, and active connections.

1. Permanent fiber optic connection (also known as fiber optic splicing) 

2. Emergency connection (also known as cold melt, related product will be mechanical connector or fast connector) 

3. Activity Connection 

How To Choose Optical Fiber Cable?

Except fiber count and fiber types, we should consider the external sheath of the cable according to its usage environment when we choose which kind of the optic fiber cable.

1. If directly burying outdoor, armored optic fiber cable should be selected such as GYTS GYTA GYXTW, etc. When overhead, a black plastic outer sheath with two or more reinforcing ribs can be used, such as self-supporting drop cable, figure-8 cable, etc.

2. If used in buildings, should care the flame retardant, toxicity, and smoke characteristics. Generally, flame retardant but smokeless types (Plenum) can be selected in pipelines or forced ventilation areas, while flame-retardant, non-toxic, and smokeless types (Riser) should be selected in exposed environments.

3. If vertically laying cables inside the building, distribution cable can be used; If deploying horizontally, breakout cables can be selected.

If the transmission distance is within 2km, multimode fiber can be selected. If the distance exceeds 2km, relay or single mode fiber can be used.

In-Depth Understanding of Fiber Optic Sensing Network

Fiber optic sensing network is a tendency for many applications. It supports a large number of sensors in a single optical fiber with high-speed, high security, and low attenuation. This article provides some information about fiber optic sensing networks.

What is Fiber Optic Sensing Network?

A fiber optic sensing network detects changes in temperature, strain, vibrations, and sound by using the physical properties of light as it travels along an optical fiber. The optical fiber itself is the sensor, resulting in thousands of continuous sensor points along the fiber length.

How Does Fiber Optic Sensing Network work?

A fiber optic sensing network works by measuring changes in the backscattered light inside of the fiber when it meets temperature, strain, and vibration.

Rayleigh scattering is produced by fluctuations in the density inside of the fiber. Raman scattering is produced by the interaction with molecular vibration inside the fiber. The intensity of anti-Stokes rays is mainly dependent on temperature. Brillouin scattering is caused by the interaction with sound waves inside the medium. The frequency is dependent on strain and temperature.

Operating Principle of Fiber Optic Sensing Network

Optical Time Domain Reflectometry (OTDR)

In the OTDR principle, a laser pulse is generated from solid-state or semiconductor lasers and is sent into the fiber. The backscattered light is analyzed for temperature monitoring. From the time it takes the backscattered light to return to the detection unit, it is possible to locate the location of the temperature event.

Optical Frequency Domain Reflectometry (OFDR)

The OFDR principle provides information about the local characteristics of temperature. This information is only available when the signal is backscattered in the function of frequency. It allows for efficient use of available bandwidth and enables distributed sensing with a maximum updated rate in the fiber.

Fiber Optic Sensing Network Technologies

Distributed Temperature Sensing (DTS): DTS uses the Raman effect to measure temperature distribution over the length of a fiber optic cable using the fiber itself as the sensing element.

Distributed Acoustic Sensing (DAS): DAS uses Rayleigh scattering in the optical fiber to detect acoustic vibration.

Distributed Strain Sensing (DSS): DSS provides spatially resolved elongation (strain) shapes along an optical fiber by combining multiple sensing cables at different positions in the asset cross-section.

Distributed Strain and Temperature Sensing (DSTS): DSTS uses Brillouin scattering in optical fibers to measure changes in temperature and strain along the length of an optical fiber.

Electricity DTS: Reliable temperature measurement of high-voltage transmission lines is essential to help meet the rising electricity demand. Fiber optic sensing, integrated into distributed temperature sensors on power lines, help ensure optimal safety and performance in both medium- and long-distance systems.

Oil and Gas DTS : Many lands and subsea oil operations rely heavily on DTS for improved safety and functionality in harsh environments. Fiber optic sensing ensures reliable performance and durability in high-temperature, high-pressure, and hydrogen-rich environments.

Oil and Gas DAS: The optical fiber in DAS creates a long sensor element that can detect high-resolution events throughout the entire length of the fiber.

Fiber Optic Navigation Sensing: Fiber optics are used in navigation systems to provide accurate information about location and direction. Aircraft, missiles, unmanned aerial vehicles (UAVs), and ground vehicles require advanced optical fiber navigation technology to ensure reliability and safety.

Fiber Optic Shape Sensing Technology: Reconstructs and displays the entire shape of optical fiber in 2D and 3D. The technology enables cutting-edge applications such as robotic, minimally invasive surgery, energy, virtual Reality (VR), etc.

Wavelength Division Multiplexing (WDM) Technology: Use of Fiber Bragg Gratings (FBGs) with different reflection wavelengths (Bragg wavelengths) in one optical fiber.

Applications

A fiber optic sensing network is used to monitor pipelines, bridges, tunnels, roadways, and railways. Also, it is used in oil & gas, power and utility, safety and security, fire detection, industrial, civil engineering, transportation, military, smart city, minimally invasive surgery, internet of thing (IoT), etc.

Conclusion

A fiber optic sensing network has high bandwidth, security, and stability,  is immune to electromagnetic interference, and is lightweight, small in size, and easy to deploy.
