Lewes, DE -- (SBWIRE) -- 05/08/2018 -- A leading market research & technology forecast consultancy addressing the fiber optics communications industry, today announced the release of a market forecast of the global consumption and technology trends of component-level fiber optic attenuators in optical fiber networks. Attenuators are used to control the power level of an optical signal used in optical fiber communication networks.

The global volume (quantity) of component-level fiber optic attenuators reached an estimated 16.6 million units in 2017. During the 2017-2023 timeframe, the value is forecasted to increase at an average annual growth rate of 3.9 percent to reach 20.9 million fiber optic component-level attenuators in 2023. The Telecommunications application is forecast to dominate the consumption of fiber optic attenuators throughout the forecast period.

In the Publisher study, the market is presented by the following product categories: Fixed (Bulkhead/Plug/Panel Mount and In-Line) and Variable Optical Attenuators (Manually-controlled and Electrically-controlled).

"The use of variable optical attenuators (VOAs) with DWDM, ROADM, optical switching, and various other applications is contributing to the steady increase of this particular component," said Stephen Montgomery, Director of the Fiber Optics group at Publisher.

Component-level electronic variable optical attenuators (EVOAs) are available utilizing various methods; however, Micro-Electro-Mechanical Systems (MEMS) is currently the most popular technique. According to Publisher, the use of manually controlled and electronic VOAs reached an estimated 2.5 million units in 2017.

Report Description
This is the Publisher worldwide market forecast of the estimated consumption of component-level fiber optic attenuators in communication applications. The optical attenuators, which are covered in this study, are components used to control (reduce) the power level of an optical signal used in optical fiber communication networks. Fiber optic attenuators are an important part of the optical communication link by allowing the adjustment of signal transmission into the dynamic range of the receiver. Either a fixed or variable attenuator is generally positioned before a receiver to adjust optical power that otherwise might fluctuate above an extreme range of the receiver's design, causing it to generate errors.

Fixed-type (not adjustable) fiber optic attenuators refer to the attenuator that can reduce the power of fiber light at a fixed value loss, for example, 5dB. While variable fiber optic attenuators refer to the attenuator that can generate an adjustable Loss to the fiber optic link. Fiber optic attenuators can be designed to use with various kinds of fiber optic connectors. The attenuators can be female-to-female, which are referred to as bulkhead- types; or male-to-female, which are referred to as plug-types. In-Line fiber optic attenuators are designed with a piece of fiber optic cable at any length and/or connectors.

Variable optical attenuators (VOAs) are either manually adjustable or electronically adjustable. VOAs have been widely used in fiber optic communication, optical signal processing, fiber optic sensing, and testing instruments, as well as many other applications.

This report quantifies stand-alone component-level fiber optic attenuators, as well as component-level fiber optic attenuators that are inside value-added or integrated modules.

When counting (quantifying) variable optical attenuator array modules and integrated modules, which may have more than one component-level attenuator, each component-level attenuator is counted separately. For example: with an integrated value-added module, we count only the complete (component-level) fiber optic attenuator as well as cost-adjusting for the optics, optical fiber alignments, and optical fiber and associated packaging, and other required materials.

Typically, fiber optic attenuators have used filter technology to decrease optical power. Light is usually transmitted from one fiber, through a spatial or temporal filter, and then focused into a second fiber for transmission through the balance of the optical links. Some of the other methods include angular (APC), lateral or axial displacement of two fiber ends, grayscale (neutral density) filters, fiber macro-bending, liquid crystals, PLC, MEMS, magneto-optic, acousto-optic or electro-optic.

Fixed attenuators (not adjustable) afford the network designer an inexpensive lumped element to decrease optical power. Packaged in either panel mount or cable assemblies, fixed attenuator types include bulkhead, connector build out, jumper/pigtailed and in-line. Attenuation is often segmented into whole decibel increments such as 1dB, 3dB, 5dB, 10dB, 13dB, 15dB and 20dB. Fiber attenuators are often associated with a connector-type, such as: LC, SC, ST, FC, MU, SC/APC, FC/APC, and other, as well as optical fiber-type (single mode and multimode).

Variable (adjustable) attenuators are ideal for simulating cable loss for research and development (laboratory) testing of optical communication link power limits or reducing power in the links where receivers are in the process of being overloaded. Fixed in-line (cable assembly/jumper) attenuators can distinguish the color band coding process to simplify the specification identification of the optical communication link components during field installation, stocking, or maintenance operations. VOAs (variable optical attenuators) enable adjustment capabilities, so the injected loss may be simply reduced as specific components degrade and increase their own attenuation over a few years.

The variable optical attenuators (VOA) is a basic building block for several optical systems such as wavelength division multiplexed (WDM) transmission systems, optical beam formers, fiber-optic adaptive controls, and other applications.

Fiber Optic Component Attenuators Global Market Forecast & Analysis 2017-2023

INFORMATION BASE
This study is based on analysis of information obtained continually over the past two decades, but updated through the end of April 2018. During this period, Publisher analysts performed interviews with selected authoritative and representative individuals in the fiber optics, telecommunications, datacom, cable TV and other communication industries, from the standpoint of both suppliers and users of fiber optic transmission links. The interviews were conducted principally with:

- Engineers, marketing personnel and management at manufacturers of fiber optic attenuators, circulators, collimators, specialty fiber, connectors, isolators, couplers, DWDM filter modules, dispersion compensators, photonic switches, modulators, transmitters/receivers, OADMs and other related optical communication components.

- Engineers, marketing, purchasing personnel and market planners at major users of passive and active optical components, such as telecommunication transmission, switching, distribution and apparatus equipment, telephone companies, data communications equipment companies, cable TV system suppliers, and a number of other end users of fiber optic communication components and technology.

The interviews covered issues of technology, pricing, contract size, reliability, documentation, installation/maintenance crafts, standards, supplier competition and other topics.

A full review of published information was also performed to supplement information obtained through interviews. The following sources were reviewed:
Professional technical journals and papers; Trade press articles
Technical conference proceedings

Personal knowledge of the research team

In analyzing and forecasting the complexities of the Global market for fiber optic communication components, it is essential that the market research team have a good and a deep understanding of the technology and of the industry. Publisher members who participated in this report were qualified.

Bottom-up Methodology
Publisher forecasts are developed initially at the lowest detail level and then summed to successively higher levels. The background market research focuses on the projected amount of each type of product used in each application in the base year (last year), and the prices paid at the first transaction from the manufacturer. This forms the base year data. Publisher analysts then forecast the growth rates in component quantity use in device type, along with price trends, based on competitive, economic and technology forecast trends, and apply these to derive long term forecasts at the lowest application (use) levels. The usage growth rate forecasts depend heavily on analysis of overall end user trends toward digital broadband communication equipment usage and economic payback.
