100GbE PICs for PTX Series Routers

Juniper Networks 4-port 100GbE PICs enable service providers to deploy high-density 100G services in a wide variety of short-reach, long-reach, and DWDM scenarios. Using modular 100-gigabit pluggable transceiver (CFP2) optics, the 4-port 100GbE PICs are designed for second-generation PTX Series Packet Transport Routers line cards (FPC2) and provide line-rate performance in Ethernet and optical transport network (OTN) applications.

Juniper Networks® PTX Series Packet Transport Routers are architected for industry-leading system density in a transport-focused design that delivers the ability to scale, rapidly qualify and deploy, and reliably support the core—all at almost half the power of other core routers. The second generation of PTX Series hardware uses an optimized packaging of the succcessful Juniper Networks Junos® Express chip for robust, line-rate, and low-latency packet performance at up to 960 Gbps per slot. The 4-port 100GbE PIC family extends the existing PTX Series PIC portfolio by offering cost-optimized flexibility of dense 100GbE solutions to service providers. The mix and match of 4-port 100GbE PICs allows for up to 64 short-reach, long-reach, and tunable1 100GbE interfaces per chassis for ultra-high speed interconnect applications. A PTX Series router fully equipped with second-generation line cards can demonstrate efficiency as high as 1.2 W/Gbps.

Architecture and Key Components

The 4-port 100GbE PICs for PTX Series line cards leverage the proven Junos Express technology in octal-Packet Forwarding Engine (PFE) configuration (FPC2). This approach combines proven and qualified hardware with advanced packaging and the latest in modular optical technology.

The 4-port 100GbE CFP2 PIC supports Ethernet over shortreach, long-reach, and extended long-reach distances in 100GbE SR10, LR4, and ER4 formats.

The 4-port 100GbE Ethernet/OTN CFP2 PIC is designed for the highest flexibility in local, and metro applications with Ethernet and OTN framing.

The 4-port 100GbE CFP2 PIC provides the benefits of a pluggable optical module in popular short-reach and long-reach applications, where OTN framing is not required. This includes the following applications:

  • Intra-POP connectivity

  • 100GbE fanout to 10GbE-optimized edge routers

  • Router to DWDM shelf connections

The 4-port 100GbE CFP2 Ethernet/OTN PIC is the most flexible 100GbE quad-port option, with connectivity to a broad range of long-haul equipment. The 4-port 100GbE CFP2 Ethernet/OTN PIC supports OTN performance monitoring, and full control over OTN features via the Juniper Networks Junos operating system.
