....not bandwidth limited [4] while copper networks are the opposite. Thus, power limits are a primary consideration when choosing the physical topology for an all optical LAN or MAN. Without ampli cation, a star topology is more power ecient than a bus or a tree and thus can support more stations [2, 4, 7, 11]. The recent development of erbiumdoped broadband optical ampli ers has revived interest in the bus and the tree [2] However, even with ampli cation, a star can support more stations than a bus in a multichannel environment because of a signi cant reduction in ampli cation bandwidth when many ....
....a star can support more stations than a bus in a multichannel environment because of a signi cant reduction in ampli cation bandwidth when many ampli ers are cascaded. In contrast, a tree or hybrid tree star topology becomes attractive since ampli ers can be installed at the roots of subtrees [11]. A pure star requires one ampli er per port. In addition, it has been shown that a tree is more cost e ective than a star for a MAN [12] Other properties besides the power budget and layout cost that must be considered when choosing the physical topology are power calibration, fault tolerance, ....

....from Figure 3. During a subframe one receiver is receiving while the other is retuning for the next subframe. Thus, only one receiver per station can be active in any subframe. The scheme proposed here assumes that pretransmission coordination is performed over a separate packet switched network [13, 14, 15]. A station wishing to establish a connection sends a request via this network to a central controller, which performs the slot allocation algorithm and notifies the stations of the slot(s) assigned to their connection. The central controller may broadcast the new slot assignments on the T WDMA ....

....is retuning for the next subframe. Thus, only one receiver per station can be active in any subframe. The scheme proposed here assumes that pretransmission coordination is performed over a separate packet switched network. The packet network can be implemented in many different ways [KP92, KG92, GKB93] A station wishing to establish a connection sends a request via this network to a central controller, which performs the slot allocation algorithm and notifies the stations of the slot(s) assigned to their connection. The central controller may broadcast the new slot assignments on the T WDMA ....
