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.

OM3 10G fiber optic patch cables which are used for 10Gigabit Ethernet applications. It also called multimode OM3 10G Aqua fiber optic cables. IEEE802.3ae defined the 10Gigabit Ethernet standards used in LANs. OM3 50/125um multimode fiber optic cables are developed for such 10Gig Ethernet applications. Plastic PE bag and cartons.

Armoured Fiber Optic Patch Cord is with stainless steel tube inside the outer jacket to protect the central unit of the cable, the armored fiber optic patch cords are easy to use in harsh environment, what is more , they are flexible as well, handling these armored fiber optic patch cables are as easy as handling electric cables. High tensile strength, pressure resistance, re-twist resistance, prevents bite by the rodents Electric cable-like handling and easy installation. Plastic PE bag and cartons.

Fiber Optic Patch Panel is a box for protecting the optical cable and pigtail splice in the cable laying. It is mainly used for the straight-through connection and branch connection of the indoor optical cable and the fixing of the cable terminal, and functions as a pigtail storage and protection joint.

Our dome fiber optic splice closure is made of PP/ABS alloy material it's strong and light, it can efficaciously prevent the lighting strike and erosion and aging and fire resist. The tray is pulled down, so it's easy installation, don't need to dismantle other trays, the material of the sealing is silica gel, it can repeatable operation.

Applications: Long distance telephone, catv, data communications. Installations: Installed in duct, self supporting (figure 8 self supporting or adss all dielectric self supporting) and direct Burial (with armouring). Construction: The cable consists of a single tube containing 2 up to 24 fibers, which is filled with water-blocking gel. When the Cable contains more than 12 fibers, they are divided in two groups. A colored thread identifies each group. Physical Protection and tensile strength are provided by aramid yarn or fiberglass wound around the tube. Either pe or lszh Jacket can be used. A ripcord is located under the jacket to facilitate jacket removal. Technical parameters: Maximum transmission distance: 6km (single mode); 0.3km (multimode) Maximum pulling load: 1500n (short term installation); 900n (long term installation) Maximum compressive load: 3000n (3.3mm loose tube diameter); 5000n (4.5mm loose tube diameter) Twist (torsion length): 125 x overall diameter Working temperature: -20íµ ~ +70íµ (pe sheath) Storage temperature: -40íµ ~ +70íµ (pe sheath) Product highlights: Small diameter and light weight. Through the control of the fiber exceed length which is the key technology in optical fiber manufacture, the fiber Cable can achieve better pulling load and operating temperature. Tube materials are water resistant and can sustain high tension. Being filled with special water-blocking gel, the Tube can provide water protection for the fibers inside the tube. Compact construction of the fiber cores can prevent the fiber to shrink back. This can sustain higher tensile stress And achieve better flexibility. íewide operating temperature range.
