“…It should be noted that, in our experiment, we emulated a worst case situation in which all ONUs see the worst case ODN loss. Anyway, on realistic PONs, users typically see different losses [16], so the quality of the transmission channel is dependent upon the physical parameters of the user requesting capacity. As the (de)modulation is performed in DSP, it is possible to implement various levels of QAM modulation coding (from e.g.…”

“…QPSK to 128-QAM) which will lead to different transmission capacity per RF channel. For instance, we can range from 500 Mbps in QPSK to 1.75 Gbps in 128-QAM over the same electrical bandwidth we used in the previous experiment to deliver 16-QAM at 1 Gbps, while other values can be obtained also varying the electrical bandwidth per channel. For each transmission to a specific user, the QAM modulation level can be adapted to achieve the maximum transmission speed and hence the minimum time occupation of that channel.…”

“…The launched power for the single-wavelength classical channels were 2.2 and 0.3 dBm. Although these power levels are slightly below the maximum signal launch as foreseen in GPON, the mere fact that the typical loss budget of deployed PONs is in the order of 22 dB [24] and therefore well below the GPON class B+ budget, makes this erosion of dynamic range due to a reduced launch permissible.…”

We investigate the practical network integration of differential phase shift quantum key distribution following a cost-optimized deployment scheme where complexity is offloaded to a centralized location. User terminal equipment for quantum state preparation at 1 GHz symbol rate is kept technologically lean through use of a directly-modulated laser as optical encoder. Integration in a passive optical network infrastructure is experimentally studied for legacy and modern optical access standards. We analyze the implications that result from Raman scattering arising from different spectral allocations of the classical channels in the O-, S-, C-and L-band, and prove that the quantum channel can co-exist with up to 19 classical channels of a fully-loaded modern access standard. Secure-key generation at a rate of 5.1×10 -7 bits/pulse at a quantum bit error ratio of 3.28% is obtained over a 13.5 km reach, 2:16 split passive network configuration. The high power difference of 93.8 dB between launched classical and quantum signals in the lit access network leads to a low penalty of 0.52% in terms of error ratio.

“…have led to the requirement of high capacity (100 Gb/s) short reach optical networks ranging from access network solutions such as fiber-to-the-home [1] to inter and intra datacenter applications [2]. Wavelength division multiplexed (WDM) systems are attracting immense interest for short reach applications due to their maturity and ability to offer a virtually unlimited capacity to the user.…”

We demonstrate a 100 Gb/s short reach system using a multicarrier transmitter based on a gain switched monolithically integrated laser. An optical comb source with 12.5-GHz free spectral range is achieved by gain-switching an integrated passive feedback laser. The 100 Gb/s wavelength division multiplexed, single sideband, direct detection, orthogonal frequency division multiplexed (WDM-SSB-DD-OFDM) system operates over 25 km standard single mode fiber exhibiting a spectral efficiency of 1.8 b/s/Hz. Receiver sensitivity of -14.2 dBm is achieved after 25 km transmission. Performance optimization with phase and amplitude precompensation is employed to improve the SSB OFDM modulation thereby reducing the interchannel interference and overcoming the power fading induced by the optical filter. We also present a theoretical analysis of the SSB-OFDM modulation.

Versatile customers, do we have FTTH solutions?

Abstract: The versatility of FTTH users i.e. the fact that users have much different characteristics in terms of requirements but also in terms of physical parameters creates an opportunity for FTTH transmission systems to optimize their performance and efficiency.
