The Singlemode Wavelength Division Multiplexer combine or separate light at different wavelengths. They offer very low insertion loss, high isolation and excellent environmental stability. These components have been extensively used in EDFA, CATV, WDM networks and fiber optic instruments.
The Optical 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. This PM Optical Circulator provides high isolation, low insertion loss, high extinction ratio and excellent environmental stability.
Motorized Variable Optical Delay Line provides precision optical path length adjustment of up to 500 ps. Driven by a stepping motor and driver has been integrated inside following the RS-232 standard, the MDL has a delay resolution about 0.76 μm (2.5 fs). In addition, its advanced motion design guarantees longevity for long-term continuous operation. Low insertion loss and high reliability make this device ideal for integration in optical coherence tomography (OCT) systems, network equipment and test instruments for precision optical path length control or timing alignment.
AFR's MEMS Optical Switch is based on an electrostatic drived micro-electro-mechanical-system (MEMS) chip. The MEMS chip consists of a tilting mirror to change light coupling between input and output fibers.The components are characterized with low insertion loss, high return loss, excellent environmental stability and reliability. The optical swtich has been widely used in fiber optics communication equipment, fiber instruments, and fiber sensing to switch channels.
The Fiber Pigtailed Photodiode is a coaxially packaged photoelectrical component. It features high responsivity, low dark current and good temperature performance over a wide wavelength range. It can be applied for channel power monitoring in DWDM system, in-line optical network switching/protection monitoring (OLP), reconfigurable optical add/drop multiplexer (ROADM), and gain attenuation monitoring in EDFAs and networks's power detection, etc.
