AFR AFR is a leading provider of Passive Optical Components, designed mainly for telecommunication, fiber laser, and fiber sensor applications. Headquartered in Hong Kong, AFR designs and manufactures advanced and cost-effective passive components through our ISO 9001-certified facility in Zhuhai, China. 

AFR specializes in high power handling fiber optic components and polarization maintaining components. Our 1064 nm high power components are capable of handling up to 20 W average, and 20 kW peak optical power for fiber laser applications. 

AFR’s fiber optic components provide an excellent platform to manipulate and guide the light through micro-optical and micro-fluidic sensor system. Polarizers, Isolators, and Splitters form the core delivery subsystem for many of these sensor platforms and are key components offered by AFR. The high performance afforded by AFR’s miniature fiber optic components allow for sensitive detection of bacteria, virus, DNA and protein, allowing for label-free single bioparticle detection and characterization.
Wavelength range: 450 – 2000 nm
Optical power handling capability: 300 mW – 50 W continuous wave, and up to 100 kW peak power for pulsed application

AFR’s fiber optic components find a broad range of applicability from telecommunications to biomedical research. The drive towards smaller and minimally invasive medical instrumentation is fertile ground for the fiber optics components offered by AFR. Optical fiber serves as both the delivery and sensing systems for in vivo optical studies. The need for controlling optical power can be readily met with AFR’s new miniature manual variable attenuator. 
When polarization control is critical to the application, our miniature inline polarizers provide the performance necessary for high quality signal filtering. These tools and more are also finding their way into laboratories around the world in which research and diagnostics are being performed for biological detection and characterization. Sensor systems continue to become more compact and with reduced power requirements that are readily met with diode laser sources. 
We are an ISO 9001-certified company, and most of our products are GR1221 qualified.  AFR has designed and developed more than 60 products for fiber optic, fiber laser, fiber sensor, ultra-broadband network, and medical equipment applications.
Product types: isolator, circulator, coupler, WDM, PBC, attenuator, delay line, etc. PM version of all those components, and high power version of all those components.
Finally, AFR is pleased to offer superior performance, excellent reliability fast response, and short lead-time.
