Whether it is feasible to replace OBU in the OSN 6800 with OAU
OAU boards have greater gain than OBU boards. Replacing OBU with OAU will increase the line gain. Large gain, however, will introduce noises. Therefore, the replacement is not recommended. You are advised to use Huawei professional WDM network optimization service to evaluate the entire network performance before determining a replacement solution.
