In this paper, we investigate a multi-packet transmitting and receiving wireless mesh network that uses a multi-antenna set on each node in the network. In wireless mesh networks for accessing the Internet, the target of all traffic generated from di

We have developed a digitally controlled AGC-EDFA by combining an FF-controlled pump-LD and a high-speed FB/FF-controlled VOA. We realized a gain excursion of less than 0.5 dB for a wide operation range.

We propose a novel system that precisely detects and unfailingly stops a propagating optical fiber fuse (FF). This system monitors the peculiar luminescence observed with the FF phenomenon, and the output of the laser light source that causes the FF

A unique PMN-PT electro-optic type VOA configuration is proposed. The VOA includes a Peltier element that enables a 100-ns range operation speed and an integrated PD that acts as a quasi-loss-less input tap-monitor.

In this paper, we propose a novel multi-antenna utilization scheme for avoiding the packet congestion around the gateway (GW) of the ad-hoc wireless networks. In our previous work, we have discussed the number of antenna design for suitable for packe
