On the performance of the electrical equalization technique in MMF links for 10-gigabit ethernet

Performance evaluation on high-speed multi-channel CWDM system by using offset-launch method and multi-stage decision feedback equalizer

“…Besides, we expand the concept of multistage DFE into the local optical network CWDM system with MMF [8,9]. In the following description, we will analyze the different offset launch in a multichannel CWDM system.…”

“…This is due to bandwidth limitations caused by modal dispersion in large-core multimode fibers. Recent developments in standardization of 10 Gigabit Ethernet include electronic dispersion compensation (EDC) to counter such limitations of multimode silica fibers [4]. E.g., the recently developed IEEE 10GBASE-LRM standard enables 10GbE at distances of up to 220 m by applying a Decision Feedback Equalizer (DFE) [5].…”

Evaluation of optical ZP-OFDM transmission performance in multimode fiber links

“…Some proposals are based on the modification of the optical transmitter by acting on the modulation signal (multilevel coding [1], wavelength division multiplexing or subcarrier multiplexing [2]) or by including equalization techniques in the receiver [3]. Orthogonal Frequency Division Multiplexing (OFDM) combines the advantages of all these techniques and it has been proved as an effective solution to increase the capacity of MMF links [4].…”
