SL93EM6X,EM6X,Huawei OTN Ethernet Processing Board

Huawei OTN Line Board SL93EM6X Overview

The EM6X board is a 6-port Ethernet processing board. It provides three 10GE optical ports, one GE optical port, and two GE fixed electrical ports. Its functional versions are SL93EM6X VER.C and SL93EM6X VER.D.

EM6X boards receive and transmit Ethernet services or carry MPLS tunnels.

To implement Ethernet service functions, the EM6X needs to work with the packet switching unit of the system control, switching, and timing board.

Function and Feature
