The Multimode Pump Protector 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. The components are characterized with high isolation, low insertion loss, high return loss, excellent environmental stability and high power handling capability.
The Unidirectional Integrated Tap Photodiode (UTPD) integrates the functionality of an optical coupler and a photodiode for optical network's power detection. The unidirectional feature allows the PD to respond to power from input port only. It can be applied for channel power monitoring in DWDM system, in-line optical network switching protection monitoring (OLP), reconfigurable optical add/drop multiplexers (ROADM), and gain/attenuation monitoring in EDFAs, network's power detection, etc.
The Polarization Maintaining Tap Isolator combines a tap coupler and polarization sensitive isolator into a single compact package. It has high extinction ratio and very low insertion loss. The PM Tap Isolator is ideal for fiber amplifier and fiber optic system where signal monitoring is required.
The Isolator Polarization Beam Combiner/Splitter is a compact device that provides both polarization beam combining and optical isolation in one integrated component. The most common application is to combine two pump lasers into one single fiber to double the pump power in EDFA or Raman Amplifier. The Beam Combiner/Splitter has extremely low insertion loss, and it can improve the amplifier performance.
