SFPs available from PDR are high performance and cost-effective modules for serial optical data communication applications, the interface converters meet the industry standard of SFP, This module is designed for single mode fiber operation at various wavelengths or multi-mode fiber operation at the wavelength of 850nm/1310nm. The transmitter section incorporates an advanced FP/DFB laser for single-mode or VCSEL for multi-mode, with temperature compensation and automatic power control circuit (APC). The receiver section incorporates an efficient InGaAs/InP PIN photodiode, with AGC for the wide dynamic range. The modules are hot-pluggable, all of them are housed in a stainless package and the combination produces a component of high reliability
