Juniper Networks 10G-40G quad small form-factor pluggable optical transceiver (QSFPP) second generation PTX Series PICs enable service providers to deploy high density 10GbE/40GbE interfaces in a wide variety of service provider, data center interconnect, Internet exchange, and public sector applications. Using configurable LAN and WAN PHY personality for 10GbE applications with optical channel transport unit (OTU2) framing via breakout cables, the 10G-40G PICs can also deliver 40GbE functionality with OTU3 wrapper. This unprecedented flexibility allows for mix-and-match of 10GbE and 40GbE applications on a single card.
