TNZ8EX4 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.
