We investigate the impact on system reach in FMF transmission due to MDL from FM-EDFAs. While mode-scrambling can reduce the growth rate of MDL with distance, there may be stringent MDL requirements for the mode-scramblers.
We experimentally demonstrate adaptive frequency-domain equalization with low algorithmic complexity for a 6×6 coherent MIMO transmission system in a few-mode fiber. Master-slave carrier recovery is also proposed and demonstrated for further reduction of algorithmic complexity.
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.
Crosstalk caused by random mode coupling can make mode-multiplexing infeasible. However, transmission of single mode over few-mode fibers is relatively insensitive to mode mixing and therefore they can be used as large-effective area fibers.
In this paper, we propose a nonuniform coded-modulation format based on iterative polar quantization (IPQ) as a scheme to enable achieving channel capacity in ultrahigh-speed optical communication systems. The proposed modulation format is coded with structured low-density parity-check (LDPC) codes optimized for Gaussian channels and, in combination with polarization-multiplexing, can achieve 800...
Todaypsilas access network is migrating towards broadband IP, fixed/mobile convergence and service convergence. Thus, the next generation access network (NGAN) requires a converged optical/wireless access network infrastructure, other than the existing architecture that connect to the cellular, broadband wireless, and optical access networks separately, which complicate the network and increase the...
