“…System designers are concerned because the system penalty is 1 dB for a crosstalk of 11 dB. 5 The adjacent channel isolation is the loss due to the nearest channel. An interesting measurement problem is how is this measured.…”

“…The power of this beat term depends on the root of the powers (if the second power is times lower than the first one, the beat term is only lower!). Furthermore this beat term depends on the frequency difference between both channels, on the phase difference in function of the time and on the initial phase difference of both channels by way of a cosine function [23], [26], [27], [37], [38], [40], [43]- [45]. Incoherent crosstalk is defined as the case in which the beat term can be neglected (e.g., when the wavelengths are different).…”

Abstract-This paper presents the results of a crosstalk analysis of four optical wavelength division multiplexed (WDM) cross-connect (OXC) topologies. An optimal set of parameters is determined to reduce the total crosstalk. The scalability of the topologies is presented in terms of wavelengths and input fibers. The total crosstalk in function of the number of cascaded OXC's is compared for the four topologies.Index Terms-Optical communication, optical crosstalk, optical cross connect (OXC), optical switches, optical wavelength conversion, wavelength division multiplexing (WDM).

“…Interference from neighboring channels behaves distinctively different from Gaussian noise; crosstalk is deterministic [23]. A reasonable assumption is to allow for a total crosstalk of -10 dB, which would give less than a 1- dB power penalty [8], [24]. With that assumption, the device in Fig.…”

The design of four-section distributed Bragg reflector (DBR) laser filters, for application in wavelength multiplexed systems with 2.5-Gb/s bitrate on each wavelength channel, has been analyzed. The results of the analysis indicate that optimized filters will support at least 10 channels and will have a dynamic range exceeding 10 dB. Bit error rate (BER) measurements on three-section DBR filters in a 2.4-Gb/s system experiment support this conclusion.
