“…. Energy ratio is regarded as the total energy dissipated by establishing TRs to support network load in the proposed structure (9,18,19). The results indicate that the TR1 obtain higher energy efficiency as compared to others at 50Gbps transmission followed by at transmission rate of 100Gbps as depicted in Fig.…”

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.

“…Even though it used less fiber lines the bandwidth capacity is reduced. The active node in star model is replaced by optical splitter or optical combiner in active star model PtM architecture Dourado et al (2018). Using optical element in the delivery line this architecture is given as passive optical network and it is popular due to its cost-effective implementation.…”

Everlasting increase of connected devices and users in communication networks carry out enormous traffic volumes. This reason places the network in a position to fine tune the energy consumption in proposal and attentive operations. Optical transmission technologies are a momentous paradigm which brings down the overall energy consumption in communication networks. This advantage increases an interest on research to improve the energy saving opportunities of optical networks. Regardless of this most vibrant research few unanswered questions direct the researchers to set effort on resolving the issues in energy efficient optical networks. Shannon limit and parallelism to support higher capacities is essential in approaching optical systems also without reducing the network performance parameters such as latency, reliability and survivability, energy consumption of optical networks must be laid out as it affects quality of services. New generation network services like optical cloud and fixed mobile convergence have necessity to meet out the end-to-end energy optimization. All these factors enlighten research area towards energy efficiency in optical network transmission. This special research work reconnoiters and consolidates the earlier research models related to energy efficient transmission in optical networks

“…Despite being energy efficient due to the passive nature in the access loop, the PON still suffers from higher power consumption due to the broadcast nature of the DS link. The power consumption trend is expected to increase further in NG-PON [12,13]. The main cause of this higher consumption of the PON is the continuous active state of ONTs to process the DS traffic because of its broadcast nature.…”

Enhanced Energy Savings with Adaptive Watchful Sleep Mode for Next Generation Passive Optical Network

et al. 2022

A single watchful sleep mode (WSM) combines the features of both cyclic sleep mode (CSM) and cyclic doze mode (CDM) in a single process by periodically turning ON and OFF the optical receiver (RX) of the optical network terminal (ONT) in a symmetric manner. This results in almost the same energy savings for the ONTs as achieved by the CSM process while significantly reducing the upstream delays. However, in this study we argue that the periodic ON and OFF periods of the ONT RX is not an energy efficient approach, as it reduces the ONT Asleep (AS) state time. Instead, this study proposes an adaptive watchful sleep mode (AWSM) in which the RX ON time of ONT is minimized during ONT Watch state by choosing it according to the length of the traffic queue of the type 1 (T1) traffic class. The performance of AWSM is compared with standard WSM and CSM schemes. The investigation reveals that by minimizing the RX ON time, the AWSM scheme achieves up to 71% average energy saving per ONT at low traffic loads. The comparative study results show that the ONT energy savings achieved by AWSM are 9% higher than the symmetric WSM with almost the same delay and delay variance performance.
