Fiber-optic ICs are key devices for building global information networks. Renesas offers a wide range of products for fiber-optic communication applications, including directly modulated laser (DML) diodes, direct modulation distributed feedback laser diodes (DFB LDs), Fabry-Perot (FP) and distributed feedback (DFB) laser diodes, and indium gallium arsenide (InGaAs) avalanche photo diode (APD) modules.
