The current electronic data centers need high power requirements, so as to offer this one a large bandwidth, low latency and low power consumption. In this context, a dynamic Flat Ball topology-based gigabit ethernet passive optical network (GE-PON) architecture with five transceivers having low latency and bandwidth reconfiguration potential to minimise energy consumption using passive devices at data centers, is presented in this paper. This architecture offers 26dB and 40dB loss in uplink and downlink respectively with 200 nodes, compared to Sandwich tree and Sirius architectures. Compared to the conventional GE-PON, it allows 9dBm in downlink and 10dBm in uplink energy saving with 1ms traffic delay. Also, it offers energy ratio up to 39% in downlink and 37% in uplink having 50 Erlang network loads at 25×100Gbps traffic rate. It provides faithful data transmission over 100km bidirectional channel considering fiber impairments and noise. The proposed design can be extended to 1:64 split ratio providing maximum 35ms in downlink and 31ms in uplink transmission delay. Comparing the Flat ball topology with other existing ones indicate the superiority of the former architecture in terms of less cost, power consumption, traffic delay and high scalability as well as flexibility.

“…Since the growth of end users' demand, the primary target of future-based high-capacity PON systems is to offer a high transmission rate, long reach, and a greater number of users. To achieve TWDM architecture at ≥100Gbps data rate, various solutions for downstream (D/S) as well as upstream (U/S) modulation formats such as on-off keying (OOK) [2][3][4][5], four-level pulse amplitude modulation (4-PAM) [6,7] and duobinary [8,9] have been considered. But these modulation formats are not feasible because of the presence of fiber dispersion, chromatic dispersion (CD), and expensive 40GHz trans-receiver.…”

The hybrid time and wavelength division multiplexing passive optical network (TWDM-PON) with a 1:128 split ratio and 16- quadrature amplitude modulation orthogonal frequency division multiplexing (QAM- OFDM) modulation system using optical code division multiple access (OCDMA) code results in high transmission security, channel capacity and robustness against interference. Thus in this paper, a bidirectional symmetric 1.6 Tbps hybrid TWDM-OFDM PON system using two-dimensional spectral/spatial-single weight zero cross-correlation (2D-S/S SWZCC) code supporting a large number of users for long-reach as well as high- speed applications has been proposed and analysed considering fiber impairments and noise. Numerically calculated receiver sensitivity (RS) and splitter power budget (SPB) are -36dBm and 23dB for downstream as well as RS and SPB for upstream transmission of -33dBm and 10dB respectively showing the supremacy of using 2D-S/S SWZCC code in the system than other OCDMA codes. Also, the simulation results show that the proposed system using 2D-SS SWZCC code provides a faithful 120km transmission distance as well as a high transmission rate of 16×15/20Gbps with a maximum received power of -32.8dBm supporting more than 190 simultaneous users. The designed PON system offers the best performance over other conventional PONs. The number of users can be increased up to 250 with an optical signal-to-noise ratio of 110 dB and -30 dBm received power.

Existing electronic data sources desire high‐power requisites, in order to obtain a large bandwidth, minimum power dissipation and low latency in networks. In this instance, a gigabit ethernet passive optical network (GEPON) architecture based on a dynamic Flat Ball topology incorporating multi‐transceivers to minimize network energy consumption via passive devices along with bandwidth reconfiguration potential and low latency is reported in this paper. The proposed architecture connected with 200 nodes exhibits 26 as well as 40 dB total loss in uplink as well as downlink considerably, compared to Sirius and Sandwich tree. Also, Flat ball GEPON architecture permits 9 and 10 dBm energy saving in downlink as well as uplink, respectively, than conventional GEPON architecture at 1 ms delay. The proposed architecture with 50 Erlang load allows energy ratio of 39% in downlink and 37% in uplink, at 25 × 100 Gbps traffic rate for 55 nodes. Besides this, the faithful fiber range of 100 km considering fiber no‐linearities and impairments can be obtained successfully. The architecture can be bordered with 1:64 splitting ratio with 35 ms in downlink as well as 31 ms in uplink transmission delay at bit error rate of 10−3. Additionally, on comparing the proposed topology with existing architectures depict its superiority with minimal implementation cost, low‐power dissipation, less traffic delay as well as high scalability and high flexibility.
