Impairments on 40 Gbit/s per Channel WDM Optical System with Wavelength Conversion

چکیده
High transport capacity optical networks, carrying information as fast as a few terabit by second, are now being developed. In this paper we discuss the major performance limiting factors imposed by each of the network’s subsystems. Optical wavelength conversion in the network’s nodes allows channel cross connecting without blocking probability. Thus, wavelength conversion based on four-wavmixing inside semiconductor optical amplifiers is also discussed. Simulation results of a four-channel system with optical wavelength conversion and total capacity of 160 Gbit/s are presented.

Gbit-Class Transmission Using SOA Data Rewriter for WDM-PON
We describe the transmission characteristics of a wavelength independent wavelength division multiplexing passive optical network (WDM-PON) based on a wavelength channel data rewriter (WCDR). The WCDR is composed of a linear amplifier (LA) and a saturated semiconductor optical amplifier (SOA), and by using the WCDR in optical network units (ONUs), we can erase the downstream signal and modulate...

متن کاملBroadcast-and-Select Switching System Based on Optical Time-Division Multiplexing (OTDM) Technology∗
This paper presents large capacity switching systems for a local network using the broadcast-and-select (B&S) architecture. The B&S switching system, based on optical time-division multiplexing (OTDM), can provide several hundreds of Gbit/s by using a nonlinear optical switch as the timechannel selector. Moreover, the combination of OTDM and wavelength-division multiplexing (WDM) can realize th...
متن کاملNonlinear Signal Distortion in WDM Transmission with 10- and 40-Gbit/s Channel Rates
Extending WDM transmission distances between regenerators and increasing the channel bit-rates are required to achieve cost-effective terabit/s backbone networks. However, the achievable performance is limited the fibre nonlinearity, with high optical launch powers and short pulse widths leading to nonlinear distortion of the signals. In this paper, we report new results of splitstep Fourier si...

We describe an optical time-division-multiplexed (OTDM)/WDM network architecture that integrates high-speed optical time-division multiplexing at speeds of 40 Gbit/s and higher with lower-bit-rate WDM channels. An ultrafast wavelength converter is used as a regenerative multifunction building block for OTDM multiplexing, WDM-to-OTDM and OTDM-to-WDM transmultiplexing, OTDM/WDM multicasting, OTDM...
