“…The high power single channel, high TRL PPM Tx met all the key requirements of the Psyche DSOC mission. Other examples of fiber laser prototypes devleoped by Fibertek can be found reference [7][8][9]. The development of a wideband, high power, gain-flat, space-qualified, WDM 1.5-µm transmitters can support NASA-SCaN roadmap, for high data rates, multiple wavelength channels, optical relay network, crosslink and multi-access configuration.…”

Fibertek is developing a power efficient, space qualifiable Eight WDM Channel PPM Downlink Tx Seed LAser Module (SAM) with TDM based FWM Mitigation Capability. SAM will be compatible with space qualifiable, high TRL, 8 WDM channel, 50W WDM Amplifier prototype that was delivered in early 2021. SAM together with the WDM Amplifier will meet all the requirements of a spaceflight DSOC WDM Transmitter. Fibertek has developed a comprehensive multi gain stage 1.5um WDM fiber amplifier numerical model that accurately quantifies the degradation of WDM PPM signals due to FWM. The physics model is used to quantify FWM-PEV for all 2 and 3 overlapping wavelength configurations of PPM orders 256-16. Results are used as inputs to a PPM statistics model that calculates the PEV statistics for all the PPM orders and WDM channels. The significant Improvements of the PEV statistics with the TDM based FWM mitigation using 2 or 3 wavelength subslots are quantified.
