Abstract
New line coding schemes called paired block codes (PBC) are investigated for application in future pure photonic networks. The first block of each pair utilises coding rule violations to simplify transmission frame structures to facilitate frame processing to complement limited capabilities of photonic logic devices. The second block is provided with sufficient redundancies to attain photonic clock recovery through logical processing. An upper bound efficiency of this type code is 75%.
