General Description
ONU is a equipment used in PON networking system to provide data service for end users.The main function of ONU is receiving the optical signals from downlink ａnd convert it into ethernet signals then deliver to users.And receiving the ethernet signals from uplink signal of users equipment or networking and switch it into optical signals then deliver to upper networking through PON networking system..
WT-101G is a Optical Network Unit of GPON series products. EPON series product uses PON technology, it precedes over the traditional optical accessing products on not only cost performance,maintainability but also extendibility.
WT-101G is a device with 1 uplink GEPON port and 1 10/100/1000M RJ45 ports, it suits for the FTTB networking syetem.
FEATURE
WT-101G be connected to OLT via ODN（Optical Distributed Net），Compose Gepon net which optical ratio is 1：32 or 1：64（Short Distence）.
