First Experimental Demonstration of Low-Cost VCSEL- Intensity Modulated End-to-End Real-Time Optical OFDM Signal Transmission at 11.25Gb/s over 25km SSMFs
VCSEL Intensity Modulated OFDM Signal Transmission
2015/5/20
Low-cost, narrow modulation bandwidth, un-cooled VCSELs can be utilized to directly modulate 64-QAM-encoded 11.25Gb/s signals for end-to-end real-time optical OFDM transmission over 25km SSMF IMDD sys...
4 Gbit/s over 50-m Large Core Diameter GI-POF using Low-cost VCSEL
Large Core Diameter GI-POF Low-cost VCSEL
2015/7/15
We report record transmission systems over 50 metres of 900-μm core diameter graded-index POF using a low-cost VCSEL at 667 nm. A net bit rate of 4 Gbit/s is achieved with BER < 10 -3 .
