Extended temperature performance of VCSEL based optical transmitter

Abstract

In this paper we demonstrate the extended temperature performance of Samtec's 12 channel FireFly optical transmitter at 10.3125 Gbps. The results indicate that the transmitter has more than 25% mask margin when operating between -40 °C and 90 °C. Reliability results for 11 different transmitters operating at 85 °C indicate that the output power of the laser changes by less than 0.5 dB after 2000 hours of continuous operation.
