R-ONU is simply

a node mounted at the home and fed from a fiber optic drop cable

each port on the NAP represents

a specific fiber all the way back to the Fiber Distribution Cabinet (FDC)

the R-ONU enclosure should be placed

above the ground and away from sprinklers or water run-off

the excess pig tail at the R-ONU should be placed

around the mounting plate

overlay or upgrade to existing building or subdivision

brownfield

because fiber drop is reinforced and not extremely flexible, do this first

figure 8 staging

new build, new building, new subdivision

greenfield

fiber optic drop up to 5000 feet long has loss of

less than 1 dB

a red indicator on the R-ONU indicates

low or no light power caused by a dirty or faulty fiber connection, bad drop or inactive port

the bundle of pre-cut fibers that are terminated inside the NAP

pig tail

when opening, closing or cleaning an FTTP optical connector

position your eyes at a 90 degree angle to the connection

device used to apply power on a coax drop

power inserter

connectors installed at the factory

pre-connectorized

fiber optic drop cable is

pre-connectorized

A soft sided apparatus that slides over the SC-APC connector of the fiber drop. The pull rope inside of the drop conduit is attached to the pull-sock allowing the tech to pull the fiber drop up to the R-ONU enclosure.

pull sock

This is a soft material fitted over a fiber drop to facilitate pulling

pull sock

a soft sided apparatus that slides over the SC-APC connector of the fiber drop

pull-sock

compared to series 6 coax drop cable, fiber optic drop cable is

similar in size but flat

the R-ONU should only transmit upstream light when

the CPE is sending an upstream data carrier

after making the connection to the R-ONU, connect at

the NAP

power is provided to the R-ONU

through a series 6 cable from the power supply, less than 50 feet

the role of the R-ONU

to convert downstream fiber optic signal to electrical RF signal

a metallic strand incorporated into the fiber drop sheath that allows for connection to a cable locating device

toning wire

NAPs come in varying port availability:

2, 4, 6, 8 and 12 ports

the optical signal utilized to deliver FTTP service through a fiber optic drop cable is classified

Class 1 LASER emission (lowest hazard potential)

A plastic piping used to house fibers, fiber drips and RF cables

Conduit

a single, shared optical fiber that uses inexpensive optical splitters to divide the single fiber into separate strands feeding individual subscribers.

EPON Ethernet Passive Optical Network

Fiber Distribution Cabinet

FDC

An enclosure that provides the connection between fiber optic cables and passive optical splitters

FDC Fiber Distribution Cabinet

Comcast services delivered using fiber optic cable run all the way to the side or inside of the customer's residence

FTTP

a pure fiber-optic cable connection running from an Internet Service Provider (ISP) directly to the user's home or business.

FTTP Fiber to the premise

a device that shuts off an electric power circuit when it detects that current is flowing along an unintended path, such as through water or a person.

GFI Ground Fault Interrupt

a composite material or fiber-reinforced polymer made of a plastic reinforced by fine fibers made of glass

GRP Glass Reinforced Plastic

New build or new construction

Hand Hole

Light Amplification by Stimulated Emission of Radiation

LASR

a classification of housing where multiple separate housing units for residential inhabitants are contained within one building or several buildings within one complex.

MDU Multi-dwelling unit

a connector for ribbon cables with four to twenty-four fibers. Connectors for singlemode fiber have angled ends to minimize back-reflection, while multimode fiber versions typically have flat ends

MPO Multi-fiber Push On

located near that residence or businness. This is where the fiber drops are connected

NAP Network access point

when doing figure 8 staging, this connector is on bottom

NAP connector

pull fiber optic drop cable from

NAP to the R-ONU

a terminal for connection of several fiber optic drop cables to the fiber distribution network

Network access point (NAP)

this should be used to clean optical connections before connecting

One Click style (dry) cleaner

a filter is designed to prevent MoCA signals from leaving your home through the cable box or radiating out of an antenna

POE Point of entry

a telecommunications technology that implements a point-to-multi-point architecture, in which unpowered Fiber Optic Splitters are used to enable a single optical fiber to serve multiple end-points such as customers, without having to provision individual fibers between the hub and customer.

PON Passive Optical Network
