Optical cross connects (OXCs) are critical components of all-optical networks. As OXC malfunction leads data loss or misrouting, surveillance of OXCs is essential to network reliability. A recent OXC supervisory scheme based on different time-delay recognition identifies the state of I/O connection through the OXC, including any possible effect of link failure or misrouting. For large-scale OXCs, requires excessively long delay fibers, which raises feasibility issues such as power amplification and length of surveillance period. This paper proposes a modified scheme for reducing the length of delay fibers without downgrading the performance
