Admonishments
Important safety admonishments are used throughout this manual to warn of possible hazards to
persons or equipment. These admonishments — in the form of Dangers, Warnings, and Cautions
— must be followed at all times. These warnings are flagged by use of the triangular alert icon
(seen below), and are listed in descending order of severity of injury or damage and likelihood of
occurrence.
General Warning and Caution Statements
1 PRODUCT DESCRIPTION
1.1 Splice Chassis
The NG4access splice chassis is a fiber optic panel designed to be mounted on an NG4access
frame in an application where on-frame splicing is desired. When used to capacity, the splice
chassis accommodates 48 splice trays, each with a capacity of up to 72 mass fusion splices, for
ISSUE DATE REASON FOR CHANGE
1 9/2012 Original.
2 10/2012 Added grounding/bonding note and updated for minor design changes.
3 July 2016 Rebranded for CommScope.
Rev C December 2017 Corrected rebranding error (removed QR code).
Danger: Danger is used to indicate the presence of a hazard that will cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.
Warning: Warning is used to indicate the presence of a hazard that can cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.
Caution: Caution is used to indicate the presence of a hazard that will or can cause minor
personal injury or property damage if the hazard is not avoided.
Danger: Avoid eye exposure to unmated connectors. Unmated connectors may emit invisible
laser radiation. Do not look directly into the end of a connector or an adapter port. Do not
inspect with a magnifying device. To ensure safety, maintain caps on unmated connectors at all
times.
Caution: Handle cables with care. Fiber optic cable stubs should be handled with care
throughout the installation procedure to avoid kinking and damage to cables.

a total capacity of 3456 splices per chassis. This number corresponds to the frame capacity
when loaded with six standard chassis equipped with LC connectors. Each standard chassis
provides 576 terminations for a total of 3456 terminations per frame.
When used for single fusion splices, each splice tray provides up to 24 heat shrink fusion
splices, for a total of 1152 splices per splice chassis.
The splice chassis has features suited for high-density applications, including the following:
• Splice trays are stacked on their narrow ends, making it possible for a large number of
trays held within the chassis. Each splice tray slot has a lance point where waxed lacing
can be anchored to secure the incoming cables as they enter the splice tray.
• The splice chassis has an area below it, at the base of the frame, where slack is stored for
the network and distribution cables routed into splice trays.
• The splice chassis travels inward and outward like a drawer providing access to the cable
slack area below the splice chassis. When the chassis is extended outward, the cable
lengthens out. When the drawer is slid in, the cable loops around below the drawer.
Figure 1 shows the main components of the splice chassis. They are as follows:
Figure 1. Main Components of Splice Chassis
•Chassis Slide—(one on each side) allows the chassis drawer to travel inward or outward
providing access to the splice trays within the splice drawer and the cable storage area
below the splice drawer.
•Tray Slot—accommodates a single splice tray, positioned on its narrow end. Each tray
slot has a dedicated lance point. Cables routed into the tray are secured with wax lacing to
the lance point.

•Lance Point—provides a tie off point for cables for each splice tray.
•Covers—(not shown) conceal splice trays within the splice chassis. The chassis has a top
cover, front cover, and bottom cover (kick plate).
1.2 Splice Tray
The NG4access splice tray installs within a NG4access splice chassis on a NG4access frame.
Each splice tray occupies one of 48 available slots in the splice chassis.
The splice tray accommodates both stranded and ribbon fiber, and both mass fusion and single
fusion splice sleeves. Each splice tray holds up to 72 mass fusion splices or 24 single fusion
splices for a total capacity of 3456 mass fusion splices or 1152 single fusion splices.
The options available for fiber types and splice chips are described in Table 2 on Page 15.
Figure 2 shows the physical features of the splice tray. They are as follows:
•Base—is the main component of the splice tray. It houses the cover and is used for storage
of cable and bare fiber slack which is wound around within it.
Figure 2. Splice Tray Features
•Fiber Breakout Deck—is a flat area containing eight holes used for tying down cables
with wax lacing. This is where cable subunits are typically broken out into bare fibers.
•Cover—lifts off at either Lift Holes or Lift Tabs. It is used for storage of bare fiber and it
holds the splice chip where fibers are spliced.
Note: CommScope recommends using only connectors, jumpers, and cables that comply
with appropriate industry standards (Telecordia GR-326-CORE, GR-20, GR-409).

3 GROUNDING AND BONDING THE CHASSIS
The splice chassis uses thread-forming mounting screws to provide an electrical path between
the chassis and the metalwork in which it is mounted. It is required that nonconductive coatings
must be removed on the mating metal surfaces. Before installation the mating surfaces must be
cleaned and coated with an antioxidant.
4 INSTALLING THE SPLICE CHASSIS
The splice chassis is installed from the rear of the frame, and always at the bottom of the frame
below the standard chassis. Before the splice chassis is installed, the frame bottom cover and
associated brackets must be removed. Use the following procedure to install the splice chassis.
1. Remove the frame bottom cover and the two brackets below the cover. Refer to Figure 4.
These items may be discarded after they are removed.
Figure 4. Removing the Frame Bottom Cover and Brackets
2. Unpack the splice chassis and ship-alongs and place them at the rear of the frame.
3. Align and secure the chassis slides as follows (refer to Figure 5):
a. Set the chassis directly behind the frame in line with the area of the frame where the
splice chassis will be installed.
b. Fully extend the chassis slides.
c. Look into the area of the frame where the splice chassis will be installed and locate the
threaded stud and two mounting holes on either side as shown in Figure 5.

d. Slide the chassis onto the threaded studs and align the mounting holes in the chassis
with the mounting holes on the frame.
e. Install a #10 washer and a 10-32 nut on each threaded stud; hand tighten.
f. Install a #12 star washer and a 12-24 x 0.5 screw in each of the four mounting holes
shown in Figure 5; hand-tighten.
g. Operate the chassis inward and outward to ensure proper alignment. If needed, adjust
support brackets and fasteners installed in steps e and f to obtain smooth operation.
h. When smooth operation has been obtained, tighten the nut on the threaded stud to 16
inch-pounds (1.8 Newton meters). Tighten the four screws in the mounting holes to 18
inch-pounds (2.0 Newton meters).
