ONU
Optical Network Unit
What powers the Fiber to the Premise (FTTP) Optical Network Unit (ONU)?
Flexpoint Power Supply installed inside the residence
Residential Optical Network Unit (ONU) that converts optical signal to RF and connects to existing coax.
RFoG (RF over Glass)
Each optical tap port on a Network Access Point (NAP) represents a unique fiber strand and is assigned to ___.
A specific home.
This will show a fiber assignment from the splitter cabinet to each home or address it serves.

What is the difference between a RFoG ONU and an EPON ONU?
RFoG converts optical signal to Broadband RF. EPON converts optical signal to Ethernet.
The nominal Optical Power Input for a Fiber to the Premise (FTTP) RFoG Optical Network Unit (ONU).
0 to -6dBm
What is the power output of the Flexpoint Power Supply that feeds power to the ONU?
12 VDC
NAP
Network Access Point
Because fiber drops come in pre-made lengths, you may have to store excess fiber in the ___.
The Pedestal or vault.
If the Status LED on the FTTP RFoG ONU is red, this means.
Optical Power Input is poor
During a FTTP installation, what are the two bonding options inside of the ONU enclosure?
- Install a ground block in the coax connected to the RF side of the ONU.2. Eliminate the ground block and connect the ground wire to the ground lug on the ONU.
This service type provides a node at every residence
FTTP
RFoG
RF over Glass
What is the max distance to the ONU that the Alpha Flexpoint Power Supply can be installed?
50 ft
If the Status LED on the FTTP RFoG ONU is green, this means.
Optical Power Input is good
This device used in Fiber to the Premise (FTTP) plant is similar to a tap in a HFC plant.
NAP (Network Access Point)
The name for a fiber node at the home.
ONU (Optical Network Unit)
The FTTP ONU’s two piece design has a lower door provided for access to ___.
The Ground Block
The output of the Optical Network Unit (ONU) at a residence in a Fiber to the Premise (FTTP) plant can be one of these two.
Broadband RF or Ethernet
EPON
Ethernet Passive Optical Network
The RF power level Output on the FTTP RFoG ONU at 1002Mhz.
19dBmV
The device at the residence that converts optical signal to electrical and electrical back to optical for the upstream.
ONU (Optical Network Unit)
This node at a home provides RF to CPE from the Optical Network Unit (ONU), is powered from the residence and provides an approximate output of 19 dBmV.
RFoG ONU (RF over Glass Optical Network Unit)
FTTP
Fiber to the Premise
What must be done with the fiber drop before you pull it through the conduit?
Unspool it
This must be done each and every time an optical drop connection is made, even if it’s a brand new install with brand new equipment.
Must be cleaned
The Alpha Flexpoint Power Supply cannot be connected to this type of power outlet.
GFI or GCFI plug
A residential fiber solution that delivers optical signal all the way to the residence.
FTTP
Two types of Optical Network Units (ONU) that can be used in Fiber to the Premise (FTTP)?
RFoG (RF over Glass) or EPON (Ethernet Passive Optical Network)
The residential Optical Network Unit (ONU) that converts optical signal to packets and connects to in home Ethernet.
EPON (Ethernet Passive Optical Network)
