Rival Signals in SOA Reach-Extended WDM-TDM-GPON Converged with RoF
Fiber Optics Optical Communications Networks Semiconductor Optical Amplifier
2015/5/26
The crosstalk of rival RoF and GPON subscribers on a RoF signal in converged RoF–WDM-TDM-GPONs with SOA as reach extender is studied. SOA nonlinear crosstalk can be mitigated by control of subscriber ...
Gain-Clamped Semiconductor Optical Amplifiers for Reach Extension of Coexisted GPON and XG-PON
GPON XG-PON Gain-Clamped Semiconductor Optical Amplifiers
2015/5/18
Optical amplification of coexisted GPON and XG-PON upstreams is demonstrated using a gain-clamped semiconductor optical amplifier (SOA). With gain clamping, performance degradation due to the cross-ga...
