Semiconductor Optical Amplifiers in avionics [PDF]
2011 IEEE Avionics, Fiber- Optics and Photonics Technology Conference, 2011 RSOAs have been demonstrated to operate within a WDM PON architectures over a >;60nm wavelength range with large path loss capabilities. Two RSOAs enable contiguous operation over the S, C and L bands; results indicate clearly that WDM architectures suitable for avionics with a PLC of >;25dB are possible with only two devices.

Доклады Белорусского государственного университета информатики и радиоэлектроники, 2021 Gigabit passive optical networks (GPON) are the most advanced technology. The data transfer rate is 2.5 Gbps for downstream and 1.25 Gbps for upstreams. But this network architecture has a limited physical network length of 20 km. This is due to the high
