Introduction

The SFH757 is a low-cost emitter diode for optical data transmission over polymer optical fiber. Its InGaAlP LED chip offers enhanced humidity resistance, with a designed emission wavelength of 650 nm. The robust SFH757 supports transmission rates up to 100 MBd and is complementary to the Avago SFH250 photodiode receiver and SFH551/1-1 integrated photodetector receiver. The SFH series is optimized for easy coupling — no fiber stripping required; simply insert a cleaved fiber into the selected SFH component. The transparent plastic housing features an aperture for insertion of a 2.2 mm fiber end face. This straightforward coupling method is highly cost-effective. The V-shaped housing allows easy coupling of unconnectorized 2.2 mm polymer optical fiber via an axial locking screw.
