744 Deployment Considerations where the crossconnect uses short-reach interfaces connected to transponders in the OLTs and to short-reach interfaces in the routers; (2) an opaque photonic crosscon- nect solution, where the photonic crossconnect (PXC) is connected to transponders in the OLTs and to short-reach interfaces in the routers; and (3) a transparent pho- tonic crossconnect solution, where the photonic crossconnect is connected to the OLTs directly without transponders, but transponders are used between the routers and the crossconnect. Assume the following: Item Cost (U.S. $) Power Footprint WDM OC-48 transponder $4,500 75 W 64 ports/rack WDM OC-192 transponder $9,000 150 W 32 ports/rack EXC switch fabric 10,000 W 1 rack EXC OC-48 port $3,000 50 W 256 ports/rack EXC OC-192 port $6,000 100 W 64 ports/rack PXC port $4,500 2 W 256 ports/rack Assume that the EXC supports a maximum of 512 OC-48 ports or 128 OC-192 ports and that the PXC supports 1024 ports. Compare the cost and floor space taken up for the three options above for the
