Abstract
The purpose of this study is to present a security system that combines PDM and SDM and is based on the flexible configuration of multi-channel keys. The proposed system will utilize three distinct approaches to accommodate a variety of rate and security needs. In order to enhance resource use and fulfill rate requirements, the three-channel PD-OFDM has been proposed. Key co-transmission schemes containing two sub-schemes for deal with different levels of encryption. Experimental results show that the proposed system can transmit 126.88 Gb/s OFDM signals in the unencrypted three-channel PD-OFDM scheme, 95.16 Gb/s OFDM signals in the one-channel key scheme and 63.44 Gb/s OFDM signals in the two-channel key scheme across 2 km 7-core fiber. Both security and speed requirements are considered to achieve a flexible system configuration.
