HuaWei H901XELD board 8-port Gigabit pon board 10G EPON OLT interface board XELD

The basic principles of HuaWei XELD are as follows:

* Control module to complete the software board loading, operation control, management and other functions.

* The switching module implements aggregation and forwarding of eight 10G EPON port signals.

* The interface module implements the conversion of 10G EPON optical signals and Ethernet packets.

* The power supply module provides working power for each function module in the board.

* The clock module provides the working clock for each function module in the board.

* Applicable to Huawei MA5800 series OLT
