About AFR:
AFR (Advanced Fiber Resources, Ltd.) is a company specializing in PM components and high power handling fiber optic components. AFR was established in 1999 by a group of fiber optic veterans, and currently AFR is under management by a team who has spent over 10 years with JDSU and other companies in Silicon Valley. We are an ISO 9001-certified company, and most of our products are GR1221 qualified. We've designed and developed more than 60 products for fiber optic, fiber laser, fiber sensor, ultra-broadband network, and medical equipment applications. Unlike traditional passive optic component suppliers, AFR is focusing on PM and high power applications, which differentiate us from our competition. Wavelength range: 850 - 2000 nm Optical power handling capability: 300 mW - 50 W continuous wave, and up to 100 kW pulsed optical power Product types: isolator, circulator, coupler, WDM, PBC, attenuator, etc. PM version of all those components, and high power version of all those components Quality: superior performance, excellent reliability Service: fast response, short leadtime
