2~18CH CWDM MUX/DEMUX Module from DK Photonics

The key components in a WDM system are the optical wavelength multiplexer (MUX), and the de-multiplexer (DEMUX). In general, a CWDM (coarse WDM) MUX/DEMUX deals with small numbers of wavelengths, typically eight, but with large spans between wavelengths (spaced typically at around 20nm). A DWDM (dense WDM) MUX/DEMUX deals with narrower wavelength spans (as small as 0.8nm, 0.4nm or even 0.2nm), and can accommodate 40, 80, or even 160 wavelengths.

The one kind of DK Photonics LGX CWDM MUX/DEMUX modules are bi-directional passive optical multiplexers and de-multiplexers, allowing multiple optical signals at different wavelengths to pass through a single optical fiber strand.

The second DK Photonics ABS CWDM MUX/DEMUX modules are duplex fiber link bi-directional multiplexers and de-multiplexers, allowing multiple optical signals’ at different wavelengths to pass through duplex optical fiber.

The last one kind is simplex directional CWDM MUX only or CWDM DEMUX only. The kind of mux and demux must be used with each other.

CWDM MUX/DEMUX solution lets operators make full use of available fiber bandwidth in local loop and enterprise architectures. Our CWDM MUX/DEMUX modules split up to 18 channels (20 nm spaced) to a single fiber. The standard packages are ABS Plastic Box, 19″ Rack Mount Chassis CWDM Mux/Demux  and LGX Metal Box Mux/Demux. No matter what kinds of connectors (such as FC, ST, SC, LC, etc.) are all available and we can also mix connectors on one device.

CWDM MUX+DEMUX 8 Channels (Dual Fiber) Module

DK Photonics offers a wide range of WDM (Wavelength Division Multiplexing) optical networking products that allow transport of any mix of services from 2Mbps up to 100Gbe over dark fiber and WDM networks providing for the entire set of the most demanding CWDM and DWDM network infrastructure needs.

2015-Fiber Optic Communication Collimators Market Forecast

Fiber optic collimator lens arrays are forecast with strong value-based growth rates of more than 30% per year (2014-2019)…

Aptos, CA (USA) – March 23, 2015 -- ElectroniCast Consultants, a leading market research & technology forecast consultancy addressing the fiber optics communications industry, today announced the release of a new market forecast of the global market consumption and technology trends of small beam collimating lens assemblies in fiber optic communication (including telecommunication, datacom and cable TV) passive and active/integrated (hybrid) components/devices.

The market study covers single lens assemblies, 2-12 lens arrays, and arrays with more than 12 lenses. Both of the lens array categories are forecast with strong growth rates of more than 30% per year (2014-2019). Single lens fiber optic collimator assemblies held the global market share lead, with over 80% in 2014.

“Collimator lenses are used in a variety of photonic products; however this market study forecasts the use of micro-sized collimator lens assemblies, which are used specifically in optical communication components/devices(such as 8CH LGX CWDM Module). Fiber optic collimator lens assemblies serve as a key indicator of the growth of the fiber optic communication component industry,” said Stephen Montgomery, Director of the Fiber Optic Component group at the California-based consultancy.

ElectroniCast defines lens assemblies as “loose” lenses (one or more), which are attached to an optical fiber or fitted/attached into (or on) a planar waveguide/array substrates or other device(s), such as a ferrule, for the purpose of collimating light for optical fiber communication.

The global consumption of fiber optic collimator lens assemblies, which are used in commercial optical communication applications, reached $287.2 million in 2014, an increase of 8.7% over the previous year.

Consumption is based on the geographical (region) location where the lens assembly is first used into (the) higher-level component or module package; therefore, ElectroniCast forecasts that the Asia Pacific Region will hold the market share lead for most of the timeframe covered in the forecast period.  America, led by the United States, is forecast to remain in the 2nd-place market position until 2019.  Europe is forecast to maintain moderate-to-strong growth, as the region is steadily involved in value-added building (and use) of sub-assemblies and equipment.  Market forecast data in the ElectroniCast report refers to consumption (use) for a particular calendar year; therefore, this data is not cumulative data.

2015-04-Fiber Optic Sensors Global Market Forecast

According to ElectroniCast, the combined use of Continuous Distributed and Point fiber optics sensors reached $2.28 Billion in 2014…

Aptos, CA (USA) – February 18, 2015  -- ElectroniCast Consultants, a leading market/technology forecast consultancy, today announced the release of their market forecast and analysis of the global consumption selected Fiber Optic Point Sensors and Continuous Distributed Fiber Optics Sensor systems.

According to ElectroniCast, the consumption value of the combined use of Continuous Distributed and Point fiber optics sensors reached $2.28 Billion in 2014.

Continuous Distributed fiber optic sensor systems involve the optic fiber with the sensors embedded with the fiber.  ElectroniCast counts each Point fiber optic sensor as one unit; however, the volume of Distributed Continuous fiber optic sensors is based on a complete optical fiber line and associated other components, which are defined as a system.

“Since a distributed continuous optical fiber line (system) may have 100s of sensing elements in a continuous-line, it is important to note that ElectroniCast counts all of those sensing elements in a distributed continuous system as one (system) unit – only.  In the case of some applications, the price of the system may be several thousand dollars,” stated Stephen Montgomery, Director of the Fiber Optics Components group at ElectroniCast Consultants.

“POINT sensors are often used in Distributed fiber optic sensor systems (installed at multiple-points/ point-to-point); however, we count their use in the Point fiber optic sensor category and not in the continuous (non-stop) distributed sensor category,” Montgomery added.

Optical isolators are devices that allow light to be transmitted in only one direction. They are most often used to prevent any light from reflecting back down the optical fiber, as this light would enter the source and cause backscattering and feedback problems. This is especially important for high data rate transceivers and transponders, or those devices requiring long span lengths between transceiver pairs. Optical feedback degrades signal-to-noise ratio and consequently bit-error rate.

“Continuing demand for upgrading communication networks to accommodate rapidly increasing bandwidth requirements will drive the steady consumption of optical fiber links. Optical isolators are used in with high-speed transmitters that are required to transmit longer distances and/or multiple wavelength transmitters,” stated Stephen Montgomery, Director of the Fiber Optics Components group at ElectroniCast Consultants.

Optical isolators are not widely used in Private Enterprise applications. The worldwide use of fiber optic isolators in Cable TV device deployments are forecast to grow in value at an annual rate of 4.9 percent (2014-2019), as optical fiber is deployed closer to the home driven by multi-media applications.

Optical isolator units are used in a variety of Military/Aerospace applications requiring rigorous testing and harsh environment fiber optic (HEFO) certification to ensure reliability and performance.  Laser-based fiber optic technology incorporating optical isolators are used in a wide variety of air, sea, ground, and space applications.

A major user-group within the Specialty application category is instrument-Laboratory/ R&D.  Optical isolators are used for noise reduction, medical imaging, pulse selection for mode locked lasers, sensing, regeneration switches, disc master, optical trapping, phase shifters, frequency modulation spectroscopy and general shuttering. The optical isolators are also used in sensing for industrial, structures and other many other communication product-oriented manufacturing/test/R&D uses.

2015-Fiber Optic Circulators Global Market Analysis

The market value of fiber optic circulators increased 10.77% in 2014…

Aptos, CA (USA) – March 9, 2015 -- ElectroniCast Consultants, a leading market research & technology forecast consultancy addressing the fiber optics communications industry, today announced the release of a new market forecast of the global consumption of fiber optic circulators in optical communications.

During 2014-2019, the consumption value is forecast to increase with rising quantity growth partially offset by declining average prices.

The fiber optic circulator market is presented by the following port-count configurations: 3-Ports; 4-Ports; and more than 4-Ports (> 4 - Ports).  According to ElectroniCast, the worldwide use of fiber optic circulators reached $244.8 million in 2014, an increase of 10.77% over he total consumption value of $227.4 million in 2013.  3-Port fiber optic circulators held an 80% market share in 2014.  Well-over 70% of the 3-Port fiber optic circulator market value in 2014 was in Telecommunication applications.

Telecommunications is set to maintain its dominant market share lead throughout the forecast period.  Specialty applications (R&D laboratory, sensors, test equipment, oil/gas, other) are set to maintain the position of second-place, according to the ElectroniCast market forecast and analysis study.

Fiber Optic Circulators are non-reciprocal devices, which means that changes in the properties of light passing through the device are not reversed when the light passes through in the opposite direction. The optical device is commonly used in a wide variety of systems, here are just a few examples: dispersion compensation, optical sensors, optical amplifiers, WDM systems, optical add/drops multiplexing (OADMs) and test/measurement instruments such as optical time-domain reflectometers (OTDRs), remote fiber (optic) test systems (RFTS) and other test equipment.

The deployment of optical fiber in the metro/access, the continuing demand for upgrading networks to accommodate rapidly increasing bandwidth requirements, plus the need for additional monitoring and testing of the optical fiber networks will drive the steady consumption of fiber optic circulators.

According to ElectroniCast Consultants, 3-Port fiber optic circulators held an 80% (value) market share in 2014…
