Performance and connectivity

The HUAWEI OptiXstar EG8145B7N-50 provides one 2.5GE port with auto-negotiation from 10 Mbit/s to 2500 Mbit/s and three GE ports with auto-negotiation from 10 Mbit/s to 1000 Mbit/s. The Ethernet ports support port-based VLAN tagging and untagging, transparent VLAN transmission, QinQ VLAN, and a limit on the number of learned MAC addresses. Its GPON interface complies with G.984.3 and G.984.5 standards and includes bidirectional FEC, SR-DBA, and NSR-DBA for efficient optical bandwidth management.

WiFi 7 wireless capabilities

The device features WiFi 7 compliant with IEEE 802.11 b/g/n/ax/be on 2.4 GHz and IEEE 802.11 a/n/ac/ax/be on 5 GHz, with 2×2 MIMO configuration on both bands and 5 dBi gain antennas. The air interface rate reaches 688 Mbit/s on 2.4 GHz and 2882 Mbit/s on 5 GHz, with a frequency bandwidth of 160 MHz. It incorporates advanced technologies such as OFDMA, MU-MIMO, Beamforming, BSS Coloring, Band steering, and WPA3 for wireless security. Multi-Link Operation (MLO) and Multi-RU optimize spectrum utilization, while support for multiple SSIDs and WPS simplifies network management.
