Huawei OSN 1800 10 Port Packet Ethernet Processing Board TNZ5EG10

Basic function

Transmits and receives the combination of 10 x GE/FE optical services or the combination of 6 x GE electrical services, and processes packet services.

NOTE:

If unshielded network cables are used, a maximum of six services is supported.If shielded network cables are used, a maximum of four services is supported.

Backplane bandwidth

The total backplane bandwidth is 10 Gbit/s.

Service processing capability

The maximum service processing capability of the board is 10 Gbit/s. If the total bandwidth of received services is greater than 10 Gbit/s, packets will be lost.

Port rate

• GE: Ethernet service at a rate of 1.25 Gbit/s.
• FE: Ethernet service at a rate of 125 Mbit/s.

Port working mode
