Solution Display
The EPON system usually consists of the OLT at the office side, the ONU and the ODN at the user side,
and adopts a point-to-multipoint network structure. The ODN consists of single-mode optical fibers and
passive optical devices such as optical splitters and optical connectors. It provides the optical transmission
medium for the physical connection between the OLT and ONU.Implement FTTX service deployment application.

The device has a built-in power template and supports two power ports.The power supply unit (PSU)
feeds the proper power voltage to the base board of OLT. Two PSUs are possible to be mounted into
rear of the chassis and it can be DC or AC type of PSU. Therefore, you need to decide to choose proper
power supply unit according to installation environment.
The power connector (AC and DC type) for main power supply is located on the rear panel of the PSU.
For redundant power feeding, the second PSU has to be used.
The below shows the electrical characteristics of the OLT：
Characteristic | DFL3000 Series |
Nominal DC power supply | DC: 36V ~ 75V |
Nominal AC power supply | AC: 100～240V; 47/63Hz |
