“…The monitored power P 3 is used for the P 2 estimation to judge in the CMS whether P 2 is smaller than the minimum detectable power P min of the OTR, i.e. the lightpath should be amplified or not [7]. For the estimation, the measured difference P 2 -P 3 is used as a correction coefficient for better estimation.…”

“…Based on the proposed amplifier modules, the amplification management scheme was investigated and evaluated together with the amplifier module, clarifying how it is decided which lightpaths are to be amplified before the lightpath reconfiguration. The amplification management function is described in detail in other paper [7], and the structure of the proposed module with an amplifier is presented and the fundamental characteristics are described in this paper.…”

A stackable module with a bidirectional CWDM amplifier has been proposed to introduce the optical amplifier into an S-ROADM for use in an IP-over-CWDM ring network, and the performance was evaluated experimentally. Packet transfer changes were monitored during the lightpath reconfigurations, including 2 lightpaths which needed optical amplifications. The result clarified that the lightpaths were reconfigured successfully, including the remote activation of the amplifiers. As a result, the stackable feature of the amplifier module enables us to provide the cost-effective introduction into the network on an implement-it-when-necessary based service in a fully compatible way with the existing stackable ROADM modules, when constructing the S-ROADM with an amplifier. Therefore, the amplifier module can be used in the same way as the ROADM modules to construct the S-ROADM, providing manually adding capability of the amplifier to in-service networks. Thus, the amplifier module has a big advantage to use it flexibly and economically in the IP-over-CWDM networks.

“…The P r value can be calculated by (1), but the values used in (1) are different from the actual values due to measurement errors and the degradation by aging. Therefore, an amplification management scheme was designed [7] such that the P r value is obtained by a power monitor (PM) in the network as described below.…”

A stackable module with a bidirectional coarse wavelength division multiplexing (CWDM) amplifier is proposed to introduce the optical amplifier into an stackable-reconfigurable optical add/drop multiplexers (S-ROADM) for use in an IP-over-CWDM ring network, and the performance is evaluated experimentally. Packet transfer changes are monitored during the lightpath reconfiguration, which needs optical amplification. The result clarify that the lightpaths are reconfigured successfully, including the remote activation of the amplifiers. As a result, the stackable feature of the amplifier module enables us to provide a costeffective introduction into the network on an implement-it-when-necessary base in a fully compatible way with the existing S-ROADM modules when constructing the S-ROADM with an amplifier. Therefore, the amplifier module can be used in the same way as the ROADM modules to construct the S-ROADM, providing manually adding capability of the amplifier to inservice networks. Thus, the amplifier module has a big advantage to use it flexibly and economically in the IP-over-CWDM ring networks.
