The Ultra Low Ratio Tap Coupler splits a very small amount of light from a signal path to a tap port. Low tap ratios such as 0.1%, 0.01% or 0.001% enable the monitoring photodetector to operate without damage or saturation. It is suitable for very high optical power, its main application is in the monitoring of optical sources such as fiber lasers.
AFR offers Thin Film Lithium Niobate (TFLN) modulator chips in different formats and data rate, including DR8 and 2 x FR4 @ 100 Gbps/lane for 800 Gbps applications and DR4 @ 400 Gbps/lane for 1.6 Tbps applications. With expereince and know-how, AFR engineers are available to customize our products to meet customers' specific requirements.
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.
AFR's Dragon 20 kW product provides QD compatible connector for high power fiber lasers up to 20 kW. Technologies incorporated include cladding mode stripping, indirect water cooling, and safety interlock.
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.
