We report on the properties of an 850nm VCSEL transmitter running at 50Gb/s with NRZ modulation from 30°C to 90°C. This is the highest transmitter operating temperature at 50Gb/s for a VCSEL link of any wavelength. This achievement is made possible by a combination of a high speed VCSEL design and driver and receiver circuits that incorporate equalization. Without equalization, the highest temperature attained with BER <1E-12 is 57°C.
