Multi-Service Packet Transport Platform
OptiX PTN 7900
OptiX PTN 7900 NE is the new generation high-capacity, high-bandwidth, and software-defined
core devices that support smart services. This NE is applicable to packet transport networks. It is
the first 10T-level SPTN NE in the field. In each slot, a 40GE or 100GE board can be smoothly
replaced with a 400GE board. A PTN 7900 NE supports smart services, visualized traffic, and the
predicable capacity. With the new software-defined networking (SDN) architecture, the PTN 7900
NE effectively supports Long Term Evolution (LTE) and various services.

Extra-high capacity, which supports bearer network long-term evolution:

Supports the maximum forwarding capacity of 3.84 Tbit/s on the equipment, which flexibly
forwards core layer traffic.

Allows a 40G or 100G board to be smoothly replaced with a 400G board in each slot, which
provides a large pipe to freely transmit services.

Super L3VPN ability to support mass base station load;

SDN-based PTN, which simplifies O&M and indicates the trend of PTN
development:

Provides standard application interfaces, which allow for user-defined programmable
services. This helps rapidly roll out new services.

Supports the separation of the control and forwarding planes and decoupling of service
features and hardware, which simplifies O&M and facilitates service innovation.

Supports the uniform management of distributed devices, which helps rapidly and efficiently
deploy and management networks.

Energy Conservation:

Supports the industry-leading distribution system and flexible configuration of power input
based on the number of boards and power consumption. The flexible configuration prevents
resource wastes.

Uses the 28 mm chips with high accuracy in the field, which supports higher performance
and lower power consumption.

Supports the intelligent heat dissipation technique and π-shaped air duct, which improves
heat dissipation efficiency.

Supports dynamic and precise energy control, which helps efficiently use energy resources.
