Introduction
The ONU-6100B-2x is an optical network unit (ONU) that
allows you to enjoy high-speed Internet access over optical
networks. The ONU-6100B-2x comes with one fiber, and one
10/100/1000 Mbps RJ-45 (LAN) port. No configuration is
required. On the ONU-6100B-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-6100B-2x models are discussed in this guide:
ONU-6100B-21 (with a 10km transceiver) and ONU-6100B-22
(with a 20km transceiver).
