Performance of optical add-drop multiplexer (OADM) for 400 channels with data rate of 20 Gbps for super dense wavelength division (SD-WDM) multiplexing system has been investigated in terms of varying transmission distance from 50 km to 250 km and 80 km to 240 km for enhancing optical communication. Long haul amplification is maintained by RAMAN-EDFA hybrid optical amplifier (HOA). Evaluation is carried out in terms of bit error rate (BER) and dispersion.
