Qumran3 is the current Broadcom StrataDNX routing silicon for carrier networks. Three parts carry the carrier roles: Qumran3U at 1.2 Tb/s for access, Qumran3A at 2.4 Tb/s for aggregation and Qumran3D at 25.6 Tb/s for core, edge, peering and DCI. IP Infusion plans OcNOS support for all three, delivered as complete routers on open hardware from UfiSpace and Edgecore.
1.2 Tb/s · Access. Cell site and business aggregation, PON OLT uplinks and metro handoff, in a 1RU router.
BCM884002.4 Tb/s · Aggregation. Carrier Ethernet, cell site routers, mobile backhaul, PON OLT, microwave access, aggregation routers and deep buffer top of rack.
BCM8849025.6 Tb/s · Core. Ethernet switching, carrier Ethernet, edge and core routers, peering, DCI and aggregation, with 800G ZR.
BCM88870IP Infusion will deliver these parts as complete routers. UfiSpace and Edgecore build the open hardware around them, and IP Infusion will supply OcNOS, the platform, the optics and one support contract.
Common to all three. A hierarchical traffic manager, deep buffering, and Ethernet OAM, MPLS and Segment Routing. Port counts and buffer size are set by the platform builder, not by the chip. What differs between the parts is capacity.
Qumran3U sits where subscriber, mobile and business traffic first aggregates. Qumran3A carries the metro rings above it. Qumran3D carries, peers and hands that traffic to another site, over coherent optics in its own ports.
The three parts cover three stages of the network, under one operating system. Each card describes what changes at that stage.
Cell site, business and PON OLT traffic aggregate into a single 1RU router. Timing and deep buffering are in the same device, so there is no separate timing appliance to power, cable and manage.
AccessAdding capacity has meant adding devices, each with its own power feed, its own cabling and its own management. A 2.4 Tb/s aggregation router absorbs that growth in ports on a device already in the rack.
AggregationConnecting sites over telco fiber has meant a separate shelf beside the router: another chassis, another power feed and a second management system for one link. With 800G ZR in a router port, the router carries the span, so the link is one device instead of two.
Core and interconnectReported savings. “A routing solution based on a single Qumran3D will save up to 66% more energy and up to 80% more rack space compared to previous generations.” Broadcom, October 2023.
Broadcom builds the silicon. UfiSpace and Edgecore build the open hardware. IP Infusion brings it together and will deliver the finished router: OcNOS, the platform, the optics and one support contract.
IP Infusion is a Broadcom Authorized Development Collaborator for StrataDNX. Its StrataDNX team has received direct training from Broadcom and works alongside Broadcom application engineers. One company delivers the software, the qualified open hardware, the optics interop and the support, so one vendor is accountable for the fix.
On the Qumran2 and Jericho2 platforms OcNOS supports today: MEF 3.0 certification for E-Line and E-LAN, achieved with OcNOS-SP-PLUS on the UfiSpace S9510-28DC, covers the business services these rings carry. Hierarchical QoS shapes and schedules by service and by tenant, so classes share a saturated uplink under a defined policy. SR-MPLS programs paths from the edge, adding capacity a node at a time without redesign.
On rings shared with mobile transport, OcNOS runs G.8275.1 full timing on the router that is forwarding, and qualified platforms meet G.8273.2 Class C per-hop specs. The class binding depends on platform and release. The platform builders separately publish Class C accuracy with an integrated Stratum 3E OCXO on the Qumran3 routers below.
OcNOS-SP sets transmit wavelength, modulation and FEC on the pluggable. That control runs today on eight Qumran2-class and Jericho2-class platforms, with proven interop from multiple vendors. Qumran3D would extend it to 800G.
Compared with a chassis. A single-chip 1RU or 2RU router replaces a chassis of line cards and supervisors. The trade-off is a larger failure domain, addressed at system level: every platform here publishes redundant hot-swap power and fans and a baseboard management controller. Node count depends on the topology.
UfiSpace and Edgecore build these routers today: two for access, one for aggregation and one for core. OcNOS support is planned across all four. Every figure below is the one the platform builder publishes.

UfiSpace product page Core · 2RUSourcing. Port and buffer figures are as published by UfiSpace and Edgecore for each platform. They differ between platforms on the same chip because both are board choices: the two Qumran3U routers above ship with a 4GB and a 16GB buffer. UfiSpace styles the access silicon as Qumran3u; this page uses Qumran3U, Qumran3A and Qumran3D throughout.
