Huawei OptiX PTN 7900E‑32 Full Product Description
Product Overview
The Huawei OptiX PTN 7900E‑32 is a flagship enhanced SDN‑enabled carrier‑grade packet transport platform of the PTN7900E series, targeting metro core‑layer as well as provincial and national backbone networking scenariosHuawei Car.... Built on SPTN software‑defined packet‑transport architecture with control‑forwarding separation, it delivers maximum 32 Tbps forwarding capacity, which can be evolved up to 64 Tbps in future upgradesHuawei Car.... It supports high‑speed interfaces including 40GE, 50GE, 100GE, 200GE and 400GE, undertaking ultra‑large‑scale 4G/5G mobile backhaul, carrier‑grade VIP private‑line, metropolitan Ethernet and large‑scale enterprise service bearing, and enables smooth evolution toward SPN transport networks.
Key Features
-
Carrier‑grade high‑availability design: Supports 1+1 hot‑backup for main‑control boards, switching fabric boards, fan trays and power modules. Multiple protection mechanisms including LSP APS, PW APS, ring‑network protection, LAG, IP FRR and VPN FRR realize 50 ms fast service recovery for mission‑critical bearer services.
-
Massive‑capacity high‑density interface access: Equipped with 32 service processing slots, supports high‑density 40GE/50GE/100GE/200GE/400GE ports, compatible with traditional GE/10GE, POS‑STM‑4 and E1 interfaces, meeting requirements for massive base‑station convergence and huge‑volume private‑line service access华为企业业....
-
High‑precision time‑frequency synchronization: Complies with IEEE 1588v2 PTP and Synchronous Ethernet (SyncE), provides high‑precision clock signals to satisfy strict synchronization requirements for 5G mobile backhaul.
-
Rich multi‑service bearing & evolution capability: Supports MPLS‑TP, SR‑TP, FlexE, iFIT, L2/L3VPN, E‑Line, E‑LAN and CES circuit emulation services. FlexE enables hard‑isolation network slicing for differentiated SLA guarantee, supporting seamless evolution from legacy PTN to SPN for future mobile bearer networksHuawei Car....
-
Standard‑compliant comprehensive OAM toolkit: Implements ITU‑T Y.1731 MPLS‑TP OAM, supports end‑to‑end fault detection, performance monitoring, traffic visualization and measurable service quality for packet‑transport services.
-
Hierarchical carrier‑grade QoS scheduling: Supports multi‑level traffic classification, policing, shaping and sophisticated queue scheduling, guarantees low‑latency and low‑jitter transmission for real‑time voice, video and core services under heavy‑load conditions.
-
Intelligent unified O&M: Compatible with Huawei iMaster NCE network‑management system, supports SDN‑driven automatic service provisioning, hot‑swappable boards and remote monitoring & maintenance, reduces OPEX for large‑scale metro and backbone transport networks.
