With AFR’s proprietary design and package technologies, our pump combiners have high coupling efficiency, high signal transfer efficiency, broad operating wavelength range, and high reliability. We have wavelength options, fiber options and optical power handling options. Customized designs are also available upon request.

Advanced Fiber Resources (AFR) recently released 2 μm Singlemode Fused Coupler.

AFR's singlemode two-micron (2000 nm) couplers offer very low insertion loss, low polarization dependence, and excellent enviromental stability. Accurate coupling ratio from 50/50 to 1/99 are available with very good uniformity in a wide wavelength range of 2000 nm windows. Different types of fibers (SMF-28 fiber or Nufern SM 1950 fiber) are available for pigtail connection selection. These components find extensively applications to perform power splitting and mornitoring  functions in all kinds oflaser systems. Customized designs are also available upon request.

Advanced Fiber Resources (AFR) newly released Unidirectional Integrated Tap Photodiode (UTPD).

AFR's Unidirectional Integrated Tap Photodiode (UTPD) integrates the functionality of an optical coupler and a photodiode for an optical network's power detection. The unidirectional feature allows the PD to respond to power from the input port only. It is widely applied for channel power monitoring in DWDM systems, in-line optical networks switching protection monitoring (OLP), re-configurable optical add/drop multiplexers (OADM), and gain/attenuation monitoring in EDFA, etc.

AFR's Unidirectional Integrated Tap Photodiode (UTPD) is characteristics with excellent directivity (up to 30 dB), low dark current, low insertion loss, low polarization dependent loss, and high return loss. Customized design is also available upon request.

In addition to Unidirectional Integrated Tap Photodiode (UTPD), AFR can also supply Fiber Pigtail Photodiode (FPPD) and Integrated Tap Photodiode (TAPD). Standard size and mini size, Polarization Maintaining (PM) fiber and Single Mode (SM) fiber are available. All of these components are Telcordia qualified.

Advanced Fiber Resources (AFR) recently released a series of two-micron (2000 nm) fiber optic components.

AFR's two-micron (2000 nm) fiber optic components are the enabling elements for the Tm-doped (or Ho-doped) fiber lasers, which have various applications in the fields of research and development, medical diagnostics and sensing, micromachining and material processing, and spectroscopy. The product portfolio includes isolators, circulators and filter-based components. Different types of fibers (SMF-28 fiber, Panda fiber, Multimode fiber or LMA fiber) are available for pigtail connection selection. High optical power ratings are optional for both the CW (continuous wave) and pulsed laser applications. These components are designed with low insertion loss, high isolation, high return loss, excellent environmental stability, and reliability. Customized designs are also available upon request.
