Introduction
The ONU-6040B-2x is an optical network unit (ONU) that
allows you to enjoy high-speed Internet access over optical
networks. The ONU-6040B-2x comes with one fiber and four
10/100 Mbps RJ-45 ports. No configuration is required. On
the ONU-6040B-2x, all device configuration is done remotely
by the OLT (Optical Line Terminal). Once you have connected
the hardware, you are ready to enjoy Internet access.
Two ONU-6040B-2x models are discussed in this guide:
ONU-6040B-21 (with a 10km transceiver) and ONU-6040B-22
(with a 20km transceiver).
