The Singlemode Coupler offers very low insertion loss and excellent environmental stability. Accurate coupling ratios from 1/99 to 50/50 are available with very good uniformity in the operating wavelength range. These components find extensive applications to perform power splitting and monitoring functions in all kinds of optical communication systems.
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.
AFR's MEMS Variable Optical Attenuator is based on an electrostatic drived micro-electro-mechanical-system (MEMS) chip. The MEMS Variable Optical Attenuator chip consists of a tilting mirror to change light coupling between input and output fibers. The components are characterized with low insertion loss, fast response and compact size. The MEMS Variable Optical Attenuator is widely uesd in WDM networks, power control or gain variation in EDFA.
The Polarization Maintaining Filter Wavelength Division Multiplexer provides wavelength division multiplexing (or demultiplexing) while maintaining signal polarization. The components are based on environmentally stable thin-film filter technology and are characterized with high extinction ratio, low insertion loss, and high return loss. They are ideal for high speed WDM network systems.
AFR's HB-CDM-130G is a quad-channel 130 GBaud high-bandwidth coherent driver modulator integrated with an RF driver, based on Thin-Film LiNbO3 chip. It is designed for 400/800 Gb/s or 1.2Tb/s coherent optical transport systems and transceivers, with baud rate over 130G per channel.
