The PPDK 1100–1650 nm 6 GHz coaxial photodiode is a specialised InGaAs PIN photodetector designed for demanding fibre-optic analogue applications. It operates across all key telecom wavelengths (O- to L-band) and delivers an RF bandwidth of over 6 GHz, allowing it to carry broadband signals and high data-rate modulation with ease.
Housed in a hermetic coaxial package with a single-mode fibre pigtail, it provides a seamless interface between optical fibres and RF circuitry. The device’s high responsivity (~0.9 A/W at 1550 nm) enhances system sensitivity. Built for reliability, it endures harsh environmental conditions (–40 to +85 °C) and meets stringent telecom standards.
Range features
A high level overview of what this range offers
