| Abstract: | The design principle of line codec is introduced for 3D image optical fiber digital transmission system used in submarine .In this design, the 5B6B coding is used and the main parts of codec circuits are completed by using programmable logic devices (CPLD). The principle of the hardware circuit and system experiment are described. The feasibility and advancement of the scheme are validated through testing. The results show that the system bit-error-ate fulfils the design requirement. |
