Abstract :
The world of telecommunications continues to grow in line with the increasing needs of the community towards telecommunications services. The need for services is increasing so that requires greater bandwidth. The Coarse Wavelength Division Multiplexing (CWDM) system can be a solution to meet bandwidth requirements, but damping can occur in remote transmissions that result in worsening system performance. We designed the CWDM system using 8 channels with 20 nm channel spacing and 60 km length of the link. To overcome the damping using the Erbium Doped Fiber Amplifier (ADFA) amplifier and Raman Optical Amplifier (ROA). The study was conducted by varying the laser power by -8, -6, -4, -2, 0, 2, 4, and 6 dBm. Based on the results of tests that have been done on Coarse Wavelength Division Multiplexing (CWDM) system using EDFA on laser power -8, -6, -4, -2, and 0 dBm Bit Error Rate (BER) and Q-factor does not meet the standard the value is below 10-12, while the 2, 4, and 6 dBm power meets the standard. However, the use of ROA at -8 dBm to 6 dBm has met the standard. Keywords: CWDM, EDFA, ROA, Power Received, Q-factor, BER
