- We proposed and demonstrated high efficient pre-spectrum sliced seed lights (PS-SL) for serving low-cost seeded wavelength division multiplexing passive optical network (WDM-PON). 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 WDM-PON OLTs. We experimentally demonstrated the feasibility of the PS-SL with multiple seeded WDM-PONs over 20 km transmission. In addition, the PS-SL was tolerated to these ranges of environmental conditions since no data error was observed after 48 h. We anticipated a considerable reduction in the seed light cost per channel for multiple WDM-PONs because the seed light cost was shared by multiple WDM-PON OLTs. © 2012 Elsevier Inc.
