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 the light of two pump lasers into one single fiber to double the pump power in EDFA or Raman Amplifier. The Isolator Polarization Beam Combiner/Splitter has extremely low insertion loss, and it can improve the amplifier performance.
The 40G-IQ-XT modulator design is based on a dual parallel structure of 2 Mach-Zehnder modulators embedded in a Mach-Zehnder super-structure. Each internal modulator is designed to have EO bandwidth above 20 GHz. Monitor photodiode is provided for automatic bias control. The 40G-IQ-XT version is provided with an extended operating temperature of - 55 to + 85°C for different environmental applications.
The Fiber Pigtailed Photodiode Array (FPDA) is a compact, multi-channel power-detecting device. It obviously simplifies module design and assembling process by pre-integrating several single power detectors in one package. It features with standard pins with 2.54 mm space that easily mount on PCB. It applies 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 network's power detection.
A micro lens was formed at the end of fiber to couple with active chips in LD and PD modules. Conical and wedge lensed fiber are both available, other shapes can be customized. And AFR can provide one stop service for fiber tail assembly, including lensed fiber, fiber metallization, AR-coating, feedthrough soldering, fiber connectorization, etc.
