We demonstrate transmissions of 25Gb/s signals from 1310nm silicon photonics transceiver over OM4 MMF through modal dispersion compensation. With the compensation fiber, ∼1dB link power penalty was achieved over 70 and 100m OM4 fiber links.
We review new options for long wavelength multimode fibers for high speed transmission at 25Gbps and present recent results for different transceivers using these new multimode fibers or operating using modal dispersion compensating multimode fibers.
We report graded index few mode fiber designs for mode-division multiplexing and demonstrate a 100-km few-mode fiber span with effective areas larger than 160 μm2 and differential mode group delay of less than 6 ps/km.
We demonstrate mode-division multiplexed transmission using the LP01 and LP11 modes over three heterogeneous spans of few-mode fiber and investigate the impact of fusion splicing and free-space coupling on mode mixing.
We demonstrate transmission of 112 Gb/s PM-QPSK signals up to 6000 km with 200 km spans. A hybrid fiber span configuration is used that combines two ultra-low loss fibers, one having very large effective area.
We demonstrate mode-division multiplexed WDM transmission using the LP01 and LP11 modes of a few-mode fiber. The signal is recovered using a 6×6 MIMO equalizer at the receiver after amplification by a few-mode EDFA.
After more than 20 years of research and development, a combination of technological, regulatory, and competitive forces are finally bringing fiber-based broadband access to commercial fruition. The three main approaches-hybrid fiber coax, fiber to the cabinet, and fiber to the home-are each vying for dominance in the industry, and each has significant future potential to grow customers and increase...
