2.5 Gbit/s data transmission with singlemode GaAs VCSELs over -20 to 100/spl deg/C temperature range

Single-mode GaAs based vertical-cavity surface-emitting lasers (VCSELs) are being investigated for high bit-rate data transmission in an industrially relevant temperature range between -20 C and 100 C. The bit-error rate (BER) for 2.5 Gbit/s transmission over 250 m of graded index multimode fibre (MMF) is better than for all temperatures under fixed bias and modulation conditions. The temperature dependent power penalty for 250 m MMF transmission is as low as 0.009 dB/K.
