Performance and Connectivity

The OptiXstar V166a-20 leverages GPON technology with upstream wavelengths of 1310 nm and downstream wavelengths of 1490 nm, along with a receiver sensitivity of −27 dBm. The GPON port supports SN, password, and combined SN+password authentication, forward error correction in both directions, and SR/NSR-DBA. The Ethernet port offers VLAN tagging, QinQ VLAN, transparent VLAN transmission, and MAC address learning with a limited number of learned addresses. The 2.5GE port automatically detects 10, 100, 1000, and 2500 Mbit/s, while the GE ports support auto-sensing for 10, 100, and 1000 Mbit/s.

Wi-Fi and Voice Features

The integrated WLAN supports IEEE 802.11 b/g/n/ax in the 2.4 GHz band and IEEE 802.11 a/n/ac/ax in the 5 GHz band, each with 2×2 MIMO, 4096 QAM, and 160 MHz bandwidth. Security standards include WPA3, WPA2, and WPA1, while MU-MIMO, multiple SSIDs, and WPS complete the wireless features. The POTS port supports a maximum REN of 4, codecs G.711A/μ, G.729a/b, and G.722, fax modes T.30/T.38/G.711, DTMF, and emergency calls via the SIP protocol.
