Optical Backplane Waveguides with 850 nm Wavelength Multimode VCSELs
An optical backplane concept based on polymer waveguides, well suited to overcome the communication bottleneck caused by conventional printed circuit boards is investigated. Attenuation coefficients are determined for several waveguides on different backplanes and it is shown that 10 Gbit/s data transmission at a bit error rate of 10 is possible both for waveguides of large (250 × 200 μm ) and ...

متن کامل35.2 Gbps 8-PAM transmission over 100 m of MMF using an 850 nm VCSEL
We report experimental demonstration of 8-PAM transmission using an 850 nm VCSEL and 100 m of OM4-type MMF. The 8-level driving signal was generated using a 3-bit DAC, the error rates were measured in real time using a conventional error analyzer. Maximum uncoded bit rate was 37.5 Gbps, which corresponds to 35.2 Gbps with 7% FEC overhead.
متن کاملPAM-4 Signaling over VCSELs with 0.13μm CMOS Chip Technology
We present results for VCSEL based links operating PAM-4 signaling using a commercial 0.13μm CMOS technology. We perform a complete link analysis of the Bit Error Rate, Q factor, random and deterministic jitter by measuring waterfall curves versus margins in time and amplitude. We demonstrate that VCSEL based PAM–4 can match or even improve performance over binary signaling under conditions of ...
متن کاملChalmers Publication Library Copyright Notice 30 Gbps 4-pam Transmission over 200 M of Mmf Using an 850 Nm Vcsel References and Links
We present high speed real time, error free 4-PAM transmission for short range optical links based on a VCSEL operating at 850 nm, a multimode fibre and a simple intensity detector. Transmission speeds of 25 Gbps and 30 Gbps are demonstrated, and the maximum fibre reaches were 300 m and 200 m, respectively. The 4-PAM is also compared with OOK transmission at 25 Gbps, and we find that at this bi...
