DESCRIPTION
This Quick Start provides instructions for the installation of the
GPON TA352/TA374 Optical Network Termination (ONT) units (P/N:
1287802F1C, 1287803F1C). The GPON TA352 4th Gen ONT has two
POTS ports and two Gigabit Ethernet ports; the GPON TA374 2nd Gen
ONT has four POTS ports and four Gigabit Ethernet ports.
The ONTs are enclosed in a weather-hardened Network Interface Device
(NID) which mounts to the exterior of a building. The figure below
illustrates the TA374 ONT in the context of the NID with the access door of
the NID removed.
Figure 1. Example NID Enclosure
The ONT is a Class 1 Laser Product.
INSTALLATION
This section explains NID installation and all cable routing.
After unpacking the ONT, inspect it for damage. If damage is noted, file a
claim with the carrier and then contact ADTRAN. For more information,
refer to the warranty.

f WARNING!
■ Read all warnings and cautions before installing or servicing this
equipment.
■ Refer to the national, state and local electrical codes for the
requirements for power, grounding, wiring, and installation methods.
■ The protective earth (PE) ground screw of this device must be properly
tightened to the grounding post of the Network Interface Device (NID).
The PE terminal of the NID must be properly grounded utilizing a 6
AWG (13.3 mm²) ground wire.
■ This equipment must be serviced by authorized service personnel
only. All repair procedures are detailed to allow
sub-assembly repairs ONLY. Authorized service personnel should not
attempt component level repairs or circuit modifications to the printed
circuit board. Improper repairs can create a safety hazard.
f CAUTION!
The buried fiber drop cable to the subscriber’s premise used in this
application must be a UL Listed non-metallic armored cable
containing no other electrically conductive materials.
Required Tools and Supplies
In addition to standard technician tools, the following tools are required for
this installation:
■ Carpenter’s level
■ 3/32 inch screw driver for connecting ONT power
■ 5/32 inch hex tamper proof bit
■ Two #10 screws (Max. Head Diameter 0.385”) and appropriate wall
anchors for mounting the NID
■ RJ-11 and RJ-45 crimpers
■ A telephony/data communication test set
■ Assorted tie wraps for securing cabling and wiring
■ Up to 4 RJ-45 and RJ-11 plugs
For fiber optic connections, you must have the following tools:
■ PON power meter with wavelength filtering
■ Fiberscope or videoscope
■ Fiber optics Fusion splicing tools
■ Fiber connector cleaning tool
■ SC/APC fiber connector
Included with the GPON TA352/TA374 packaging are 2/4 Two-screw
Terminal Bridges (2 for the TA352 and 4 for the TA374), an SC/APC fiber
jumper, and a 7-position power and alarm connector. For data, the
connection to the ONT is through the RJ-45 Ethernet connectors
. For
POTS, the connection is made through the 2/4 Two-screw Terminal
Bridges.
Installation Steps
To install the ONT, complete the following steps:
■ “Mount the NID Enclosure”
■ “Ground the NID”
■ “Install the ONT”
■ “Route the Fiber Connection”
■ “Connect Power/Alarm”
■ “Install a Local Power Source”
