This paper introduces a new optical device model named as an optical cross add and drop multiplexer (OXADM) which has potential use in CWDM metro area networks. The device uses the concepts of combination of optical add/drop multiplexing and optical cross connect between two main transmission lines in order to implement the wavelength routing operation. MEMS optical switches are integrated in the...
We demonstrate a newly invented device named as optical cross add and drop multiplexer (OXADM) which designed with a combined concept of optical cross connect (OXC) and optical add drop multilexer (OADM). It is designed by improving all drawbacks appear in the previous device with some interesting features added. The OXADM node focuses on providing functionalities of transport, multiplexing, routing,...
Aa analytical approach is presented for modeling crosstalk and to evaluate the bit error rate (BER) performance in a wavelength division-multiplexing (WDM) network for link with optical cross connect (OXC) without wavelength converter. Factors that affect the magnitude of crosstalk in the OXC are investigated and parameters that play important role in determining magnitude of crosstalk and BER are...
An analytical approach is presented for modelling crosstalk and to evaluate the bit error rate (BER) performance in a wavelength division multiplexing (WDM) network for link with optical cross connect (OXC). Factors that affect the magnitude of crosstalk in the OXC are investigated and identified. The effects of OXC induced crosstalk on the BER performance is evaluated at a bit rate of 10 Gb/s by...
