Cisco's P-OTS: Denser and distributed
Cisco Systems’ carrier packet transport (CPT) product family adds metro packet optical transport to its existing switch and router offerings.
Cisco claims the CPT is its second-generation packet optical transport system (P-OTS), complementing the ONS 15454. But some analysts view the CPT as the vendor’s first true packet optical transport product.
"This announcement is an acknowledgement that P-OTS equipment is important and that operators are insisting on it"
