Good Forecasts for Global Optical Fiber Cable Market

Posted on by

An optical fiber cable uses light wave for voice and data transmission, its data transmission capacity is 4.5 times more than conventional copper cables. So in the past several decades, we have seen that fiber optic cables are superior to traditional copper twisted-pair cable or coaxial cable because of its unique physical characteristics, allowing information to travel at speeds increasingly approaching the speed of light without interference between adjacent wavelengths. In leading market, the global drive to implement FTTx into more new venues is good news for the market of optical fiber cables. Another good trend is that the price erosion of optical fiber cables had been 10 to 15 percent annually, in result that the demand of optical fiber cable is expected to continue growing in the foreseeable future. And the growing data transmission workloads placed by high-performance computers, servers and network storage systems is helping spur growth in the market. Consequently, fiber optic cables are now the indispensable backbone of today’s communication network. This article will analyse the global optical fiber cable market in three main applications, including long-distance communication, submarine cable and FTTx network.

Submarine Optical Fiber Cable Market

Submarine optical fiber cables are undersea cables used for carrying data across interconnected networks between continents. With the advancements of technology, most of the submarine optical fiber cables that currently form the backbone of the Internet connect the U.S. to Europe and Asia by crossing the Atlantic or Pacific oceans. Instead, there is a proposal for deployment of Trans-polar submarine cable system in Arctic Ocean. Laying an undersea fiber optic cable is meant to connect Asia and Europe by crossing the Arctic Circle – the shortest practical distance yet for Internet signals traveling between the two continents. According to the report by Global Industry Analysts (GIA), cumulative installations of submarine optical fiber cables globally are projected to reach 2 million kilometers by 2020, driven by the growing demand for fiber broadband and the ensuing deployment of fiber optic cables in the Internet backbone. Presently, submarine optical fiber cables transmit 100% of the international Internet traffic, and more than 95% of the world’s combined data and voice traffic.

Optical Fiber Cable Market in FTTx Networks

In recent years, the market for optical fiber cable has shifted dramatically to local deployments, away from long haul and regional. This is the impact of FTTx, which calls for far more dense applications in neighborhoods, cities and other highly focused areas. Optical fiber cable is being caught up in the global move to broadband in the near future. The next generation of high bandwidth applications, along with the proliferation of connected devices, is expected to require faster and higher bandwidth networks which will require the use of multimode fiber cable for data transfer. This growth in the FTTx networks in turn is expected to drive the fiber optics market. Future Market Insights (FMI) forecasts the global fiber to the home (FTTH) market’s value will grow from $9.5 billion in 2017 to more than $37 billion by the end of 2027, a 14.4% compound annual growth rate (CAGR). In the leading Asian economies, more than 44% of all homes and buildings are already directly connected to the fiber optic cable network; in North America penetration is 8.4%, in Europe 5.6%.

Final Thought

Fiber optic cable is widely used for data transmission and is increasingly being used in place of metal wires because of its efficiency and high transmission capacity. Since the use and demand for great bandwidth and fast speed, there is no doubt that fiber optic transmission will bring more opportunities and be continuously researched and expanded to cater for future demands. However, although fiber optic cable in itself is considered a long-term stable investment, it also faces huge challenge. The major restraint in the fiber optics market is the growing use of wireless communications systems in remote areas.

FTTX PON – the Replacement of Copper Network

Posted on by

Introduction

FTTX (Fiber-To-The-X) is know as different Passive Optical Network (PON) configurations which can be used to describe any optical fiber network that replaces all or part of a copper network. It is different from the traditional fiber optic network used for Local Area Network (LAN) applications.

A key difference between FTTX and the traditional fiber optic network is the number of optical fibers required for each user. In most FTTX applications, only one optical fiber is used. The single optical fiber passes data in both directions (bidirectional, or BiDi). This is very different from a LAN application where the transmit optical fiber sends data in one direction and the receive optical fiber sends data in the other direction. In a LAN application, both optical fibers can have data passing through them at the same time.

1000BASE-T SFPA transceiver, or converter, is typically a device that has two receptacles or ports. One mates with the transmit optical fiber and the other mates with the receive optical fiber. This allows the device to be transmitting and receiving simultaneously. This is known as full-duplex operation, e.g., a 1000BASE-T SFP transceiver with a RJ45 port can take advantage of this operation. In an FTTX single optical fiber application, full-duplex operation is typically not possible; usually only half-duplex operation takes place. This means that part of the time the optical fiber is carrying a signal in one direction, and the rest of the time, it is carrying a signal in the other direction. The key to making this system work is timing. Data is sent downstream for a predetermined amount of time and then data is sent upstream for a predetermined amount of time. This process is also known as Time Division Multiplexing (TDM).

FTTX systems typically use multiple wavelengths. The downstream laser is always a different wavelength than the upstream laser. The downstream laser is typically the longer wavelength, such as 1480 nm or 1550 nm (or both), and the upstream laser is typically 1310 nm. FTTX is possible with optical fiber distances up to 20 km because optical fiber is capable of transmitting information with a very low level of loss. The typical loss for an FTTX optical fiber at 1550 nm is 0.25 dB/km and 0.35 dB/km at 1310 nm.

Types of FTTX

According to the X, there are Fiber-To-The-Home (FTTH), Fiber-To-The-Building (FTTB), Fiber-To-The-Curb (FTTC), Fiber-To-The-Node (FTTN), Fiber-To-The-Desk (FTTD), etc.

FTTH

Fiber to Copper Media ConverterAn FTTH PON uses optical fiber from the central office to the home; there are no active electronics helping with the transmission of data in between the two locations. The central office is a communications switching facility. It houses a large number of complex switches that establish temporary connections between subscriber lines that terminate at the central office. At the home, a converter box (e.g., a Fiber to Copper Media Converter with SFP and RJ45 ports) changes the optical signal from the optical fiber into electrical signals. The converter box interfaces with existing home cabling such as coaxial cabling for cable TV, twisted-pair cabling for telephone, and Category 5e or 6 cabling for Internet connectivity.

FTTB

An FTTB PON is very similar to an FTTH PON. It uses optical fiber from the central office to the building and there are no electronics helping with transmission in between. The optical signal from the optical fiber is converted into electrical signals in a converter box at the building. The converter box interfaces with existing cabling such as coaxial cabling for cable TV, twisted-pair cabling for telephone, and Category 5e or 6 cabling for Internet coonectivity.

FTTC

In an FTTC PON, optical fiber runs from the central office and stops at the curb. The “curb” may be right in front of the house or some distance down the block. The converter box is located where the optical fiber stops, and it changes the optical signal from the optical fiber into electrical signals. These electrical signals are typically brought into the home through some existing copper cabling. The electrical signals may need to be processed by another converter box inside the house to interface with existing cabling such as coaxial cabling for cable TV, twisted-pair cabling for telephone, and Category 5e or 6 cabling for Internet coonectivity.

FTTN

FTTN is sometimes referred to as fiber to the neighborhood. An FTTN PON only has optical fiber from the central office to the node. The node is typically a telecommunications cabinet that serves a neighborhood or section of a neighborhood. The optical signal from the optical fiber is converted into electrical signals inside the telecommunications cabinet. These electrical signals are distributed throughout the neighborhood through existing copper cables to the houses.

FTTD

FTTD is a ideal of FTTX solution. Fiber connection is installed from the main computer room to a terminal or fiber media converter near the user’s desktop. FTTD is a high-bandwidth solution that expands the traditional fiber backbone system by running fiber directly to desktops. It is a horizontal wiring option that pushes the available bandwidth beyond 10G. It is an intriguing, underestimated and overlooked way to create a beneficial system that is expandable and performance-driven.
