Deployment analysis of TDM/WDM Single Fiber PON with Colourless ONU Operating at 2.5 Gbps Subcarrier Multiplexed Downstream and 1.25 Gbps Upstream
Optical communications Optical networks
2015/6/5
A single-fiber full-duplex hybrid TDM/WDM-PON is demonstrated to operate at 2.5/1.25 Gbps rates, with RSOA ONU. It achieves high power budget (GPON compliant) at a distances higher than 20km, and serv...
Dispersion Analysis of the ADI-FDTD and S-FDTD Methods
Symplectic finite-difference time-domain (S-FDTD) method alternating-direction-implicit finite-difference time-domain (ADI-FDTD) method
2009/7/28
Numerical dispersion performances of ADI-FDTD and S-FDTD methods have been compared. It has been shown that for time steps below the stability limits of the S-FDTD method it has much better dispersion...
