TNZ5EX4 overview

TNZ5EX4 4*10GE(XFP) ethernet processing board applied to Huawei OSN 1800V.

The EX4 board is a packet board. It supports access of 10GE LAN services and transmits service signals to cross-connect boards for packet data processing and centralized grooming at the equipment level. On the WDM side, the EX4 board works with a board providing the packet service processing function to implement packet service transmission on the WDM network.

The EX4 board receives and transmits a maximum of 4 10GE LAN optical services. The EX4 board implements Ethernet service functions by working with packet switching units on the system control, switching, and timing boards.


Item TNZ5EX4
Basic function Receives and transmits the following services:
4 x 10GE LAN
Backplane bandwidth 40 Gbit/s
