UPS Uninterruptible Power Supply
A weather hardened box that is set into the ground typically at grade level. It houses cable equipment, NAP's, and splice cases.
Vault
a technology or technique modulating numerous data streams, i.e. optical carrier signals of varying wavelengths (colors) of laser light, onto a single optical fiber.
WDM Wave Division Multiplexing
enables unique and separate modes of light at different wavelengths to be transported through the same optical medium

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

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

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.

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.

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.

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

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.
