Backbone is the main track or channel in a network with very high speeds. Because the distance to be traveled in the link of this sea cable communication system is very far, it is necessary that devices such as optical amplifier to overcome the lost power when transmitted so that the communication can be delivered to the receiver. Optical amplifier used in the form of EDFA (Erbium Doped Fiber Amplifier), EDFA is an optical amplifier used to increase signal level that works on Waves 1530 nm to 1570 nm. This research analyzes the influence of the use of optical amplifier against SKKL network on link java-Bali by using Brancing Unit configuration and without Brancing Unit, Brancing Unit is a device to divide the optical path and connect more than one landing station, and measure the performance based on the performing parameters such as BER (Bit Error Rate), Q-Factor, Power Receive, and SNR (Signal to Noise Ratio). This research successfully simulates the configuration of Brancing Unit and without Brancing Unit. Simulated results by varying the power of 0, 2, 4, 6 and 8 dBm, Of the two configurations used have a good performance with the highest value of the BER parameter of 2.83×10-115, Q-Factor of 24.35139, Power Receive of16.1937 dBm, and Signal to Noise Ratio of 31.1411947 dB at 8 dBm power, and The smallest value of the BER parameter of 1, 21×10-10, Q-Factor of 6.752785, Power Receive of-25.287 dBm, and Signal to Noise Ratio of 11.3714564 dB at power 0 dBm.
