“…The proposed scenario sketched in Fig. 2(b) stands in stark contrast to earlier works on optically driven energy harvesting [ [9][10][11][12][13][14][15][16][17][18]. This is because prior works primarily focused on the provisioning of a large supply currents in the range of tens of mA required for a low-voltage actuation of opto-electromechanical elements such as latching switches.…”

“…At the same time, monitoring functionality can be integrated with these remotely powered network nodes, supporting network operations, and allowing access to network segments that would otherwise be too remote to the operator's point of presence. Prior work has demonstrated the identification of network users connected to the ports of a splitter through binary power monitoring with an array of 8 photodiodes [12,13] and intelligent demarcation points at the tail-end edge of an access network [14]. The spectral monitoring of a wavelength division multiplexed (WDM) feeder has been demonstrated using a remotely powered optical spectrum analyzer based on a liquid-crystal-on-silicon device serving as a spatial light modulator, allowing for an acquisition of the spectrum with coarse WDM (CWDM) resolution [15].…”

The introduction of avalanche photodetectors in optical interconnects can extend the unallocated optical budget while unleashing further opportunities to migrate to novel datacenter network architectures. The required high-voltage rail that biases the photodiodes would involve a specialized electronic circuitry but will be instead harvested directly at the optical layer, taking advantage of the dropped power during optical modulation at local transmitters. Rather than dumping light resulting from extinct space bits, we will collect this contribution and convert it to a high-voltage bias by means of a photovoltaic power conversion circuit that is shared among and powered from all constituent data lanes of the optical interconnect. We will experimentally demonstrate that this energy reclamation circuit can sustain the sourced current during avalanche photodetection whilst maintaining a bias rail at ~25V with continuity, as will be proven for up to 64 data lanes. We demonstrate an optical budget of ~30 dB for 10 Gb/s/lane transmission, with a reception penalty as small as 0.2 dB with respect to an electrically biased photoreceiver. We will further elaborate on the limitations linked to the proposed concept, such as in terms of dynamic range.

“…Telemetry is gaining attention besides EON as well. A dedicated low-rate data-plane telemetry channel has been recently proposed and evaluated in the context of Passive Optical Networks (PON) to monitor the connections between an intelligent remote splitter and attached Optical Network Units (ONUs) [12].…”

Accurate real-time availability of transmission parameters at the network controller has the potential to significantly improve the efficiency of control and management operations, particularly in the case of soft failures where detection and localization procedures are typically affected by the long monitoring time intervals usually adopted in current Elastic Optical Networks (EONs). In this paper, we report on the design, implementation and experimental demonstration of a telemetry service exploiting the gRPC protocol to enable on-demand streaming of real-time monitoring parameters, dynamically retrieved from a configurable set of network devices. The telemetry service is efficiently introduced for Software Defined Networking in EONs, also accounting for disaggregated network elements through standard YANG-defined network models. The implemented telemetry service is experimentally validated for partial and fully disaggregated architectures over networking scenarios where soft failures not addressable through traditional monitoring solutions are successfully detected and localized. Moreover, detailed performance evaluation is conducted varying the number of subscribed network elements, the type of communication (e.g., compressed vs. uncompressed, bundled vs. unbundled), showing remarkable scalability performance particularly in the case of compressed and bundled telemetry configurations.

We propose a symmetric 10 × 10 Gb/s bidirectional wavelength division multiplexed passive optical link having a length of 80‐km supported only by Raman amplification through pre‐amplified data modulated uplink channels. The conventionally ignored wavelength region of E‐band has been utilized for employing pre‐amplified data modulated Raman pumps. The proposed network allows the use of single low‐cost and low‐power amplifier for distributed Raman amplification instead of multiple high‐cost Raman laser pump modules.
