Abstract

Recent demonstrations have shown the benefits of using Raman amplification for transmitting high bit rates over long distances for both repeatered terrestrial and unrepeatered submarine applications. A multi-reach terrestrial field trial using Raman amplification was recently completed in conjunction with Verizon Business. The field trial verified the feasibility of upgrading an existing network to transmit a mixture of 10 Gb/s and 40 Gb/s over a record setting distance of 3040 km. In addition, an unrepeatered submarine demonstration was recently completed to show the versatility of all-Raman amplification and its ability to transmit a mixture of 40 Gb/s (OC-768) and 10 Gb/s signals over a long unrepeatered link. Together these demonstrations show the versatility of all-Raman amplification to support high-bandwidth requirements over increasingly longer distances. This paper reports on the record setting multi-reach field trial and provides the results of the recently completed demonstration to transmit a mixture of 40 Gb/s and 10 Gb/s signals over an unrepeatered distance of 400 km.
