“…This challenge is being overcome at 10 Gbit/s and below as system tests have shown. [63,64] Moreover, electrical precompensation methods have also been demonstrated in single channel 10 Gbit/s experiments. Such electrical precompensation enabled transmission over 5120 km of standard step index fiber without any optical chromatic dispersion compensation [65].…”

Abstract. Tunable dispersion has been implemented in various technology platforms, including fiber gratings, planar waveguides, thin film etalons, and bulk optic technologies. This paper will focus on fiber grating based tunable dispersion compensation, because fiber gratings are at present one of the best developed TDC technologies available. The paper is divided into three parts. In the first part we describe grating based TDC technologies and discuss their advantages and disadvantages. We focus on thermally tuned linearly chirped fiber gratings, as these have to date been the most successful grating technology for 40 Gbit/s. We also compare grating TDCs to two other prominent tunable dispersion technologies: thin film etalons and planar waveguide ring resonators. In the second section we describe the techniques used to fabricate high performance dispersion compensation gratings as well as the theory of the primary defect of fiber grating dispersion compensation: group delay ripple (GDR). In the third section we describe the telecom system related issues for tunable gratings, including characterization of grating performance, tunability requirements and results from actual system trials using tunable FBGs.

“…On the other hand, logic processing and bitwise feedback at high data rates is not easily implemented in the optical domain. Studied for over 10 years for lightwave systems [81][82][83][84][85][86], electronic equalization at 10 Gb/s has recently experienced a boost by progress in high-speed integrated circuits, and has proven a powerful tool to increase dispersion tolerance [91][92][93][94][95]. Equalization techniques range from multi-tap feed-forward and decision feedback structures to sophisticated schemes employing multiple thresholds in conjunction with FEC.…”

“…The offset launch relies on exciting only a subset of all propagating modes of the MMF, and the modal dispersion is lower. It is very attractive to combine the technologies including the offset-launching at the transmitter end, decision feedback equalization at the receiver end, and the directly modulated DFB source [4,5]. Some reports used vertical cavity surface-emitting lasers (VCSELs) as laser source in CWDM system [6].…”
