Patent ID: 7505687

Claim:
An interdomain optical transport system comprising: a first transponder photonically connected to a first end user device, wherein the first transponder is configured to receive a first photonic signal from the first end user device and to convert the first photonic signal to a long range photonic signal for transmission over a long haul network; a first course optical filter connected to the first transponder; a first fine optical filter connected to the first coarse optical filter; a second transponder photonically connected to the first transponder via the long haul network and a metro network, wherein the second transponder is further connected to a second end user device, wherein the second transponder is configured to receive the long range photonic signal, to convert the long range photonic signal to a second photonic signal, and to transmit the second photonic signal to the second end user device, and wherein communication between the first and second end user devices is accomplished without translation between a short range signal format and a long range signal format.
