The Singlemode Wavelength Division Multiplexer combine or separate light at different wavelengths. They offer very low insertion loss, low polarization dependent loss, high isolation and excellent environmental stability. These components have been extensively used in raman amplifier, CATV, WDM networks and fiber optic instruments.
The Mini Fiber Optic Circulator is a compact, high performance lightwave component that routes incoming signals from Port 1 to Port 2, and incoming Port 2 signals to Port 3. The optical circulator provides high isolation, low insertion loss, low PDL, low PMD and excellent environmental stability. It is widely used in combination with fiber gratings and other reflective components in DWDM systems, high speed systems and bi-direction communication systems.
The Pump Protector is a micro optics device based on environmentally stable thin-film filter technology. It is used to block out unwanted noise signals in EDFAs and fiber laser systems. The components are characterized with high isolation, low insertion loss, high return loss, excellent environmental stability and high power handling capability.
The Multimode Fiber Bandpass Filter is a micro optic device based on environmentally stable thin film filter technology. It is used to block out unwanted noise signals in multimode fiber communication systems. These components are characterized with high isolation, low insertion loss, high return loss, excellent environmental stability and high power handling capability.
AFR's Integrated Polarization Maintaining Tap Power Detector (PMTAPD) integrates the functionality of a optical coupler and a photodiode for optical network's power detection. It applys for channel power monitoring in DWDM system, in-line optical network switchingprotection monitoring(OLP), re-configurable optical add/drop multiplexer(OADM), and gain/attenuation monitoring in EDFA, etc.
