“…When Δt λ is 100 ns, Δt Link−Up of less than 20 ms is achieved at the fastest. Similar results are obtained for ONUs #2 and #3 since Δt λ is not dependent on the range of the wavelength shift due to the arrayed configuration of the transceivers [17].…”

This paper proposes a novel wavelength-tuning (λ-tuning) optical line terminal (OLT) protection method for wavelength division multiplexing/time division multiplexing-passive optical networks (WDM/TDM-PONs). Since λ-tuning OLT protection achieves redundancy of OLT ports utilizing only the λ-tunability of optical network units (ONUs) that ONUs intrinsically have for colorless operation, no additional equipment such as redundant OLT ports or optical switches is necessary for the protection. The proposed method is based on backup wavelength pre-assignment and a discovery process. Since the backup wavelengths are pre-assigned, the proposed method shortens the service outage time and balances traffic loads among the active OLT ports after OLT protection. Therefore, the proposed method achieves high-level reliability cost-effectively. Through system demonstrations using media access control boards and λ-selective burst-mode transceivers for symmetric 40-Gb/s WDM/TDM-PONs, the validity of the proposal is examined based on the link-up time and throughput measurement for λ-tuning OLT-protection.Index Terms-Optical access network, optical access system, passive optical network (PON), passive optical network (PON) protection, wavelength division multiplexing/time division multiplexing-passive optical network (WDM/TDM-PON).

SUMMARYImprovement of conventional networks with an incremental approach is an important design method for the development of the future internet. For this approach, we are developing a future aggregation network based on passive optical network (PON) technology to achieve both cost-effectiveness and high reliability. In this paper, we propose a timeslot (TS) synchronization method for sharing a TS from an optical burst mode transceiver between any route of arbitrary fiber length by changing both the route of the TS transmission and the TS control timing on the optical burst mode transceiver. We show the effectiveness of the proposed method for exchanging TSs in bidirectional bufferless wavelength division multiplexing (WDM) and time division multiplexing (TDM) multi-ring networks under the condition of the occurrence of a link failure through prototype systems. Also, we evaluate the reduction of the required number of optical interfaces in a multi-ring network by applying the proposed method.

“…Thus, of importance is the investigation of the advantages and disadvantages of different OLT-Tx configurations containing SOA boosters and of different OLT-Rx configurations containing SOA preamplifiers in a PON-specific environment. SOAs have been used as OLT-boosters/preamplifiers in different PON concepts [1] and recently in a few NG-PON2 applications [2,3]. A study of different OLT-Tx/Rx configurations for NG-PON2 deploying SOAs is first introduced in [4] and is further extended within this paper.…”

Optical line termination transmitter (Tx) and receiver (Rx) concepts using a semiconductor optical amplifier (SOA) for the next generation of passive optical networks (NG-PON2) are experimentally compared. In general, a single SOA per wavelength channel at the Tx and a configuration comprising a single SOA followed by avalanche photodiodes (APDs) at the Rx are beneficial in terms of signal quality and power dynamic range. Additionally, we introduce a cost-effective bi-directional SOA approach for simultaneous upstream preamplification and downstream boosting. Our results indicate its feasibility for mid-class loss budget classes of NG-PON2.Index Terms-Next-generation passive optical network (NG-PON2); Passive optical network (PON); Semiconductor optical amplifier (SOA); Time-and-wavelength-division multiplexing passive optical network (TWDM-PON).
