Short-Length Fbg

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

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).

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

í= Applications:
Short and medium distance, indoor and protected environments. Offered as a riser, plenum, or general purpose cable,
it is used for interconnection of distribution boxes, or the distribution boxes and customer equipments, and between
floors.
í= Installations:
Installed along the wall, the roof, interlayer, canal and indoor.
í= Construction:
The cable contains 4 to 72 fibers individually buffered to 0.9 mm in a tight or semi tight construction and coded. The
cable structure depends on the number of fibers: The 4 to 12 fiber cables contain individual fibers without sub-units,In
the 16 to 72 fiber cables the fibers are grouped in the sub-units. In the 4 to 12 fiber cables, the individual fibers are
stranded and protected by aramid yarn and a PVC or LSZH jacket. In the 16 to 72 fiber cables, the fibers are grouped
into sub-units which are laid helically along the cable axis. Each sub-unit contains 4 to 6 fibers, aramid yarn and a
PVC or LSZH jacket. The 72 fiber cable consists of twelve sub-units, nine of them are stranded around a central
element made of 3 sub-units.
