Discovery Semiconductors introduced its first commercially available 40 Gb Dual-Depletion InGaAs/InP p-i-n Photodiode at the Optical Fiber Conference in Dallas, Texas, in 1997. Since that OFC, we have expanded our pioneering dual-depletion photodiode design for several cutting edge products such as Balanced Photodiodes for 40 Gb, and Ultra-fast photodiodes up to 60 GHz. Today, our 40 Gb product line has evolved to include PIN+TIA optical receivers, with both linear and limiting amplifiers. These receivers work up to 40 Gb from 1064 nm to 1650 nm for single mode applications, and additionally up to 25 Gb for 850 nm multimode applications. For 25 Gb data rates, these receivers come with an optional CDR. Additionally, we supply 40 Gb Integrated Balanced Optical Receivers for 40 Gb DPSK/DQPSK systems. For busy test stations or student labs, where users of different experience levels might be handling high value opto-electronics that are easily damaged by mishandling, order your photodiode to be mounted in our Lab Buddy instrument.
