FBG (Fiber Bragg Grating)

Alxenses’s offers a series of fiber-optics products based on Fiber Bragg Grating (FBG) technology. FBG is produced in optical silica fibers by creating periodic refractive index variations in the fiber core using UV laser light. FBG is an in-line optical filter and its reflection wavelength and spectral shape depends on the periodicity, length as well as depth of the refractive index changes of the grating structure. FBG exhibits very low loss and is low-cost compared to the bulk-optics counter parts. By altering the grating periodicity and refractive index change, FBGs for various fiber-optics communication and sensing applications can be easily produced.

Features:
•High reliability and stability
•High reflectivity
•High side-lobe suppression ratio
•Low insertion loss
•Narrow bandwidth optical filter
•Immunity to EMI
•Multiplexing capability


Applications:
•Strain fiber optics sensor
•Temperature fiber optics sensor
•Displacement fiber optics sensor
•Humidity fiber optics sensor


Both Acrylate and Polyimide coated FBGs are available.


Note:

Acrylate and polyimide are the two common coating materials for optical fiber. The polyimide coating withstands higher operating temperature (up to 300°C) than Acrylate material (up to 85°C).


Features:
•High reliability and stability
•High reflectivity
•High side-lobe suppression ratio
•Low insertion loss
•Narrow bandwidth optical filter
•Immunity to EMI
•Multiplexing capability


Applications:
•Strain fiber optics sensor
•Temperature fiber optics sensor
•Displacement fiber optics sensor
•Humidity fiber optics sensor

Chirped FBG (Fiber Bragg Grating)

Alxenses’s Chirped fiber Bragg grating is an in-fiber broadband reflective optical filter. Using advanced fabrication technique and production facilities, grating period and refractive index modulation depth along the length of FBG can be precisely controlled to produce chirped fiber Bragg grating with different spectral and dispersion characteristic. The broad bandwidth and customizable spectral shape of chirped fiber Bragg grating is particularly effective in gain and spectral flattening of EDFA or ASE optical source.


Features:
•Low insertion loss
•Customize reflection spectrum
•Wide bandwidth


Applications:
•ASE filtering
•EDFA gain flattening
•Broadband reflector for fiber laser
•Dispersion compensation

Fbg (fiber bragg grating) array


Alxenses’s fiber bragg grating (fbg) array is produced using advanced fabrication technique to write many fbgs in a single strand of optical fiber without any splicing points. The mechanical strength of alxenses’s fbg arrays is therefore significantly better than fbg arrays produced by slicing many fbg arrays produced by slicing many fbgs together. The high quality fbg array with customized wavelength and spacing allow distributed measurement over long distance. Fbg arrays are particular suitable for large-scale sensing in strain, temperature or pressure monitoring in oil, gas, civil engineering, aviation and marine industries.

Features:
•low insertion loss
•spliceless fbg array
•customized fbg array configuration
•accurate fbg wavelength and reflectivity

Applications:
•large-scale strain and temperature monitoring in oil, gas, civil engineering, aviation and marine industries.

Short-Length FBG

Alxenses’s short-length FBG is fabricated based on advanced FBG fabrication technique and production facilities. The Bragg wavelength and length of the FBG can be controlled precisely while maintaining high reflectivity and side-lobe suppression ratio.

The standard length of short-length FBG is 3mm and can be customized to various lengths upon request. The short-length FBG allows smaller form-factor housing to be used for FBG packaging that is necessary when sensor size is a concern. Short-length FBG is suitable for building small sensors for temperature and strain measurements and compact sensor arrays for distributed monitoring applications.

Features:
•Short length
•Low insertion loss
•Multiplexing of FBG sensors in single fiber

Applications:
•Small form-factor sensor packaging


Note:

In general, the bandwidth becomes wider when the length of FBG gets shorter.

Coconut Coir Fiber

$180 - $200
MOQ: 10  Tons (US)
Sample Available
 
Coconut fibers is an eco - friendly material which are found between the hard, internal shell of the outer coat of a coconut. After fully mature coconuts are harvested, they are put into machines to separate the long bristle fibres underneath the skin of the nut. This process is called wet-milling. The coconut fiber is relatively waterproof, and is one of the few enviromental materials that are resistant to damage by seawater.

Coir Fibre

$250
MOQ: 12  Tons (US)
Supplier From Madurai, Tamil Nadu, India
 
Coir fibre is the major product that is extracted from the coconut husk. Coir fibres have a multitude of different applications and they are available in blocks and bales as well. The coir fibres are generally used in the production of ropes, mats and mattresses. The coir fibres that are extracted from the inner layer of the outer part of the coir husk are used in large scale production of the ropes, mattresses and brushes.

Coir fibre is also the main product used in manufacturing the geotextiles. Geotextiles have a wide range of uses. But it is mainly used in limiting the soil erosion. Soil erosion has become one of the most prevalent problems of our society. Although there are various methods for limiting it but the erosion can be successfully kept in check by the use of geotextiles. Moreover, the geotextiles are also used in various types of road works and for surrounding the dams.
