Optical inter-satellite links are a promising technology for constructing satellite backbone networks, owing to their high data transmission capacity and lightweight terminals. To circumvent the data-rate bottlenecks and structural complexity associated with optical-electrical-optical conversion, all-optical signal processing is essential. This paper addresses a commonthe challenge at the relaying nodes of satellite backbone networks: of handling concurrent access requests from multiple laser links, a common scenario at the relaying nodes of satellite backbone networks. We propose and validate an all-optical data access system based on an optical time-lens. The system demonstrates robust performance and high modulation format compatibility., It successfully processinges intensity-modulated, phase-modulated, and hybrid-format inputs entirely in the optical domain. The system's reliability is further confirmed under practical conditions, including uneven wavelength spans and unequal data rates among the accessing optical inter-satellite links., as evidenced by measured bit-error rates It achieves bit-error rates below 10−7 and supports optical inter-satellite link transmission distances exceeding 4,500 km, even under hybrid modulation formats. With its simple structure and high compatibility, the proposed system offers a scalable solution for future multi-format satellite backbone networks, supporting transmission distances exceeding 4,500 km even under hybrid modulation formats.
