Optical Communications systems transmit data as modulated light pulses through fiber-optic cables or free-space links, enabling extremely high-bandwidth data transfer over long distances. Photodetectors at the receiver end must convert these optical signals back into electrical signals with high speed and sensitivity. GPD provides InGaAs and germanium photodetectors designed for optical communications applications at standard telecom wavelengths, including 1310 nm and 1550 nm, supporting data rates from low-speed monitoring systems to high-bandwidth coherent transmission networks in commercial and defense infrastructure.
