Product Information
Lumia P300T is the multi-terabit central switching blade for Lumia T6 and T14 OLT chassis. It aggregates subscriber-blade traffic and provides carrier-class network connectivity, switching and routing for large residential, business and mobile-backhaul fibre-access deployments.
A standalone P300T provides 1.7 Tbps switching capacity and up to 300 Gbps uplink connectivity. Two blades can operate in dual-unit stacking mode as one nonblocking switch with 3.4 Tbps switching capacity, up to 600 Gbps uplink connectivity and a single management IP address. Each central blade connects every subscriber blade through 200 Gbps of backplane capacity, providing up to 400 Gbps per subscriber blade when two central blades are installed. Advanced functions include provider-edge bridging, selective Q-in-Q, hierarchical QoS, IPv4 and IPv6 routing, OSPF, PIM-SM, multicast control, SyncE, Stratum 3E and PTP. Some routing and VRF capabilities are explicitly identified as roadmap items in the datasheet and must not be presented as generally available without release-level confirmation.
Technical data
| Access Ports | Central switching and aggregation blade for Lumia T6 and T14 terabit chassis. Supports subscriber blades carrying Combo PON, XGS-PON, GPON, 10GE P2P and other technologies supported by the chassis architecture. Provides Layer-2 switching and Layer-3 routing functions. |
|---|---|
| Subscriber Scale | Provides up to 400 Gbps connectivity per subscriber blade when two P300T blades are installed. Overall subscriber scale depends on the Lumia chassis and installed subscriber blades; Lumia T14 configurations can support more than 50,000 users. |
| Uplinks | 2 x 100GE QSFP28; 4 x 1GE/10GE SFP+ or 25GE SFP28; 2 x 10/100/1000Base-T RJ-45. Up to 300 Gbps uplink connectivity standalone or 600 Gbps with two stacked blades. |
| Switching | 1.7 Tbps standalone or 3.4 Tbps in dual-unit stacking mode; 128k MAC entries; jumbo packets up to 12,288 bytes; backplane interfaces equivalent to 48 x 10/25GE or 12 x 100GE per subscriber blade; 6 x 25GE inter-switch connectivity. |
| Dimensions | Central switching blade for Lumia T6 and Lumia T14 terabit chassis. Blade dimensions are not separately stated in the controlled datasheet. |
