Neptune 1250
High Availability Access Router for Access Edge and Pre-Aggregation

The Neptune (NPT) 1250 is a fully redundant, modular routerdesigned to provide a multi-access edge and pre-aggregation forservices, applications and architectures requiring a high-availability
multiservice solution. With support for eCPRI, XGSPON, network
slicing, advanced timing and multiple access technologies, it is idealfor operators who want a multi-access Hub in their xHaul network.
NPT 1250 provides 560Gbit interface switching, 300 Gbit/s processing capacity and 100G interfaces in a 2 RU form factor. It provides anextensive set of interfaces for multiple access technologies such as Ethernet, MPLS, PON and legacy TDM(CES), and has the capacity to be
used for pre-aggregation or a large access edge deployment. With a full set IP/MPLS, transport capabilities, the NPT 1250 can efficientlyaggregate and route the services over the network, meeting their service performance needs (SLAs) on a service by service basis. Fullredundancy and support for segment routing and MPLS-TP make the NPT 1250 a perfect fit for operators delivering business and missioncritical services.
NPT 1250 supports a full set of optical interfaces including 100G ZR/ZR+ coherent optical pluggables, this allows it to support both singlelayer, hop-by-hop IPoDWDM and multilayer IP and Optical transport. The operator can choose which approach best meets their needs, orthey can run both in a hybrid approach.
With such a rich and robust feature-set, the NPT 1250 is well suited for a wide variety of applications and networking scenarios,these include;•5G multi-access Hub: with 5G specificfunctionality including, Class C timing,
Segment Routing, Flex-Algo, EVPN, FlexE and5G interfaces•CIN Switch for MSOs: Providing the IP routing
capabilities needed as MSOs evolve to CIN in asmall compact form factor•Mission critical applications and networks:
With high availability and support for
deterministic packet transport with MLPS-TP,
segment routing and RSVP-TE•

Pre-aggregation for Broadband services:
providing a full set of IP/MPLS capabilities
providing optimized service-aware support forvoice, video, and data services
