This paper is a tutorial reviewing research and development performed over the last few years to extend the reach of passive optical networks using technology such as optical amplifiers.
Upon endoplasmic reticulum (ER) stress, the transmembrane endoribonuclease Ire1α performs mRNA cleavage reactions to increase the ER folding capacity. It is unclear how the low abundant Ire1α… (More)
Long-reach access networks such as the hybrid TDM-WDM-PON studied in the EU-funded project PIEMAN reduce node count and increase bandwidth per customer, but require challenging opto-electronic… (More)
In eukaryotic cells, roughly one-fourth of all mRNAs code for secretory and membrane proteins. This class of proteins must first be segregated to the endoplasmic reticulum, where they are either… (More)
We investigate the performance of an amplified GPON system under conditions of unequal burst powers from ONTs. Successful operation is shown for power differences up to 14 dB as might be expected in… (More)
IRE1α is an endoplasmic reticulum (ER) localized endonuclease activated by misfolded proteins in the ER. Previously, we demonstrated that IRE1α forms a complex with the Sec61 translocon, to which its… (More)
Results of a field experiment with a prototype managed GPON reach extender for underground deployment are described. The reach extender has 1+1 protection switching to geographically diverse OLTs.
The results of a detailed study of the performance of 40-Gbit/s optical transmission over standard single-mode fiber with alternate-phase return-to-zero (AP-RZ) modulation formats are presented.… (More)
We achieved a 40% increase in 40-Gb/s transmission distance in links with exact dispersion compensation through suppression of nonlinear distortion by using the alternate-phase return-to-zero (AP-RZ)… (More)
We investigate the mitigation of distortion due to self-phase modulation and dispersion in 40-Gb/s nonreturn-to-zero wavelength-division-multiplexed transmission using a multichannel optical… (More)
