Huawei MA5800 Series OLT MA5800-X7 Service Subrack

The MA5800 is the industry's first smart aggregation OLT with a distributed architecture. It is positioned as an OLT oriented to the ultra-gigabit era. The product is designed to help carriers build networks with larger bandwidths, higher speeds, and smarter connectivity to deliver better service experience.

• Providing GPON, 10G PON (including XG-PON and XGS-PON), 50G-PON, P2P 10GE/2.5GE/GE access, the MA5800 supports deployment on FTTH, FTTD, FTTB, and FTTC networks. This makes it applicable to home access, enterprise access, mobile backhaul, and Wi-Fi hotspot backhaul scenarios to aggregate all services on one fiber network.
• The MA5800 functions as a large-capacity aggregation device on the network to aggregate the traffic from ONTs, MDUs, and campus switches, thereby simplifying the network architecture and reducing the OPEX.

The MA5800-X7 subrack has 2 ground points. One is on the left side panel and the other is in the middle of the right mounting bracket of the subrack.

The power input end of the MA5800-X7 has a noise filter. The center ground of the noise filter connects to the subrack, known as the chassis ground or protection ground. Ground the subrack enclosure securely to divert the induced or leaked current to the ground and improve the protection against electromagnetic interference.

Use a ground cable to connect the ground point of the subrack enclosure to the ground bar of the telecommunications room or to the ground directly. It is recommended that the grounding resistance of the telecommunications room should be less than 10 ohms. Refer to the local standards before grounding the subrack.
