Advanced Fiber Resources (AFR) drew a lot of attention at the 2019 Laser World of Photonics with the unveiling of its ClearCut kW Package-Free Fiber Bragg Grating, a new device that improves FBG user experience.

AFR’s ClearCut kW Package-Free Fiber Bragg Grating

Controlling temperature has long been a challenge when using FBG devices. The typical solution has been to dissipate excess heat using a mounting structure or package. The extra mounting, however, creates difficulties with installation and true temperature monitoring of the FBG area.

AFR’s ClearCut kW Package-Free FBG may be bent and mounted in any position along with other fibers, eliminating the need for a separate mounting structure or package and maintaining an ultra-low temperature rising without adding extra cooling. Additionally, this product may add an FBG area temperature monitor, to help users or engineers improve real-time data analysis, and ensuring system safety.

“The ClearCut kW Package-Free FBG product well represents AFR’s technical capability. It makes AFR a more One-Stop-Shop for fiber laser components. We are committed to the continuous advancement in product technology and product quality.” said Kevin Zhang, AFR’s VP of Engineering.

Small in size, big on capability, AFR’s ClearCut kW Package-Free FBG ensures more than 2.0 kW pump power and 1.5 kW signal power handling with outstanding reliability. It has passed the critical qualification tests including low/high temperature storage, temperature cycling, fiber pull and high humidity.

Advanced Fiber Resources (AFR) released several new high power products, including 1.5 kW ClearCut Grating, 6 kW or Higher 7x1 Laser Combiner Module, 6 kW or Higher 18x1 or (18+1)x1 Pump Combiner and Dragon 6000 W Laser Cable.

Advanced Fiber Resources (AFR) released its 1550 nm 20 W Fiber Isolator (PM & SM), which used at the output port of pulsed fiber lasers to prevent any errant beams from returning to the fiber amplifier. This new isolator may be used in both common fiber laser applications and ultra-fast lasers with high peak power. Our unique manufacturing process and epoxy-free optical path design enhance the device's ability to handle high power. It is ideal for systems using highly reflective materials, and in high-speed communications.

AFR can also provide a remarkable range of customized optical solutions such as Fiber Delivery Collimator, 100 W Fiber to Free Space Isolator, Integrated Tap Photodiode Isolator (TPDI) so on. For detail, please contact AFR's sales account manager for your requirements.

Advanced Fiber Resources (AFR) released its Integrated Tap Photodiode Isolator integrates the functionality of a miniature polarization insensitive with a tap photodiode for power monitoring in one package. The product provides a more compact solution in EDFA or other modules where both Isolator and monitoring function are needed.

AFR can also provide a remarkable range of customized optical solutions such as Fiber Delivery Collimator, 100 W Fiber to Free Space Isolator, Metalized Fiber Cable so on. For detail, please contact AFR's sales account manager for your requirements.

Advanced Fiber Resources (AFR) released its Metalized Fiber Cable which available for singlemode, multimode or polarization maintaining fiber. The product special design provides in-house controlled metallization and meets Telcordia requirements.

Metalized Fiber Cable contains a metal film which deposited on the fiber surface using a sputtering process. This metalized fiber cable can be soldered into a package to achieve a hermetically sealed environment that also provides a highly reliable interconnection for optical devices. The fiber is specifically designed for optoelectronic packaging and can be used in passive and active devices.
