In this paper, the transmission performance of 4× 10?? Gbps wavelength division
multiplexing system using optical cross add and drop multiplexer (OXADM) with 0.1 nm
channel spacing has been demonstrated and the effect of insertion loss, attenuation and
crosstalk has been investigated. It is found that the signal can be transmitted with acceptable
BER up to 85 km without amplification at insertion loss 6 dB with an attenuation of 50 dB. In
addition, it is also observed that the system provides acceptable performance with maximum …
