Demonstration of performance enhanced pre-spectrum sliced seed light for low-cost seeded WDMPON architecture
We proposed and demonstrated high efficient pre-spectrum sliced seed lights (PS-SL) for serving low-cost seeded wavelength division multiplexing passive optical network (WDMPON). The PS-SLs reused backward amplified spontaneous emission light which were generated by an Erbium doped fiber amplifier (EDFA) to improve output characteristics. The power, flatness and bandwidth of seed signal from the proposed PS-SL were sufficient to serve multiple seeded WDMPON OLTs. We experimentally demonstrated the feasibility of the PS-SL with multiple seeded WDMPONs over 20km transmission. In addition, the PS-SL was tolerated to these ranges of environmental conditions since no data error was observed after 48h. We anticipated a considerable reduction in the seed light cost per channel for multiple WDMPONs because the seed light cost was shared by multiple WDMPON OLTs.
