“…3(iii). Although, the data rates of the E/O and O/E are required to be twice that of the original electrical signals due to the multiplexing of two signals, 40 Gbps (4 channels × 10 Gbps) optical modules suitable for space conditions have already been developed [5], in addition to which, up to 400 Gbps products are available for terrestrial telecommunications.…”

Optical TDM technology for N+1 redundant systems in high resolution optical earth observation satellites

Optical remote sensing has been greatly expanded by the construction of satellite constellations and improving the performance of the optical sensors. As the data throughput of earth observation satellites increases, photonic technology is expected to be used for the interconnections within the payload in order to reduce its overall size, mass, and power consumption, and to improve its immunity to EMI. Here, we propose an optical time division multiplexing technology for N + 1 redundancy in the payload, which is able to improve reliability by reducing the number of active components in the satellites, and present a feasibility study on its transmission efficiency.

“…Additionally, interconnections using optical fibers have been introduced in order to further increase the data throughput, to reduce the size, mass, and power consumption, and to improve the immunity to EMI [4]. 40 Gbps (4 channels × 10 Gbps) optical modules for space conditions have been developed for the optical interconnections [5].…”
