For carriers that have been using technologies such as Ethernet over Sonet, Cisco is proposing that they change to the CPT, using Ethernet transport and MPLS-TP.
The CPT600, CPT200, and CPT50 (6-slot, 2-slot, and fixed-configuration, respectively) combine Ethernet switching, DWDM transponders, Optical Transport Network (OTN) support, and Reconfigurable Optical Add/Drop Multiplexer (ROADM) capabilities. General availability is scheduled for the first quarter.
Why this matters
Cisco's contribution to P-OTS so far has been restricted to IP over DWDM, a very router-centric alternative. CPT shows that Cisco is willing to pitch P-OTS to carriers' optical transport groups as well as their router experts. In fact, the product family was developed by Cisco's optical group, the division in charge of the ONS 15454 line.
It's been no surprise to see Cisco back MPLS-TP, an Ethernet transport option that would play off the company's Multiprotocol Label Switching (MPLS) franchise, but the CPT shows why Cisco is so gung-ho about the technology.
