POFLink fiber optic solutions deliver on the harsh demands of the electric and diesel train industry, ensuring the integrity of control,signaling and passenger data not be compromised by the harsh environment in which these applications operate. POFLink developed our light sources and communications ICs with the deep understanding of the stresses and strains placed on equipment in electric and diesel trains. Our light sources use Resonant Cavity LED (RCLED) technology to ensure the strongest optical output at the lowest currents while preserving stability after decades of operation. Our robust receiver topologies guarantee error-free transmissions every time.
