ADMONISHMENTS
Important safety admonishments are used throughout this manual to warn of possible hazards to
persons or equipment. An admonishment identifies a possible hazard and then explains what
may happen if the hazard is not avoided. The 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 SAFETY PRECAUTIONS
LIST OF ACRONYMS AND ABBREVIATIONS
The following acronyms are used in this manual:
FMDF Fiber Main Distributing Frame
FTB Fiber Termination Block
FTB w/MPO Fiber Termination Block With MPO Connectors
MPO Multifiber Push-on Connector
NGF Next Generation Frame
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: Infrared radiation is invisible and can seriously damage the retina of the eye. Do not
look into the ends of any optical fiber. Do not look directly into the optical adapters of the
adapter packs. Exposure to invisible laser radiation may result. An optical power meter should
be used to verify active fibers. A protective cap or hood MUST be immediately placed over any
radiating adapter or optical fiber connector to avoid the potential of dangerous amounts of
radiation exposure. This practice also prevents dirt particles from entering the adapter or
connector.

1 PRODUCT DESCRIPTION
This section describes the CommScope Fiber Termination Block with MPO Connectors (FTB
w/MPO). The FTB w/MPO is available with 96, 144, or 192 terminations per block.
1.1 General Description
The FTB w/MPO is used on a NGF rack to provide a point for terminating MPO trunk cables.
The FTB separates out the multiple circuits within each MPO connector into its component
individual circuits. The circuits are terminated to factory-installed pigtails that are routed within
the FTB to individual connectors in sliding adapter packs. Figure 1 shows the FTB exploded out
from an NGF frame.
MPO trunk cables terminate at the rear of the FTB where the MPO connectors mounted in the
block are accessed. Cross-connect or interconnect patch cords terminate at the front of the FTB
where the sliding adapter packs are accessed. The NGF rack, on which the FTB is mounted,
provides physical support and cable management.
The FTB w/MPO has a left or right orientation for installation on either the left or right side of
the NGF rack (as viewed from the front).

1.2 Product Function
An MPO trunk cable contains multiple fibers terminated at a single connector. The FTB
separates out the multiple circuits within each MPO connector into its component individual
circuits. The individual circuits are routed through pigtails to individual connectors on sliding
adapter packs. By sliding out an adapter pack and connecting an interconnect or cross-connect
patch cord, a technician easily routes an individual circuit to a local device. In a reverse
direction, the FTB can be used to consolidate 12 individual circuits into a single MPO cable for
routing within a facility or to a network element. Figure 2 is a schematic of product function.
Figure 2. FTB w/MPO Product Function
1.3 Main Components
An FTB w/MPO block consists of a sheet metal chassis with physical features providing for
mounting of MPO connectors on the back of the chassis, mounting of sliding adapter packs on
the front, and placement of factory-installed internal pigtails between the MPO connectors and
sliding adapters. The 96-position chassis accepts sliding adapter packs with four adapters each.
The adapters are arranged in twelve rows, each with two adapter packs (12x2x4). The 144-
position chassis accepts sliding adapter packs with six adapters each (12 rows of 2x6). The 192-
position chassis accepts sliding adapter packs with eight adapters each (12 rows of 2x8). The
adapter packs are available with SC and LC ultra-polish adapters. Figure 3 shows the 144
position chassis.
The FTB chassis has a removable side cover and two hinged front covers. Removing the side
cover provides access to the rear cable management area where the connectors used for
terminating MPO trunk cables are located. The rear cable management area also has an upper
radius limiter and other features designed for securing and routing a MPO trunk cable.

1.5 Accessories
The following accessories are available for use with the FTB:
•Patch Cords—Are available with specified connectors in standard lengths of 6.0, 7.0, 8.0,
9.0, 10.0, and 12.0 meters.
•Connector Cleaning Kit—Provides all the materials required to clean fiber optic
connectors and adapters. Two types are required: a ferrule mote kit for the adapter
connectors on front of the block, and an MPO kit for the MPO connectors on back.
1.6 Applications
The FTB may be used to support either interconnect or cross-connect frame applications. Both
are described below.
1.6.1 Interconnect Application
In an interconnect application, only MPO trunk cables are terminated at the rear of the frame.
Network elements are connected directly to the trunk cables using interconnect patch cords. The
excess patch cord slack is stored in the slack storage area on the front of the frame. Figure 4
shows a typical interconnect application using the FMDF. An interconnect application uses the
entire frame for terminating trunk cables. An overhead or underfloor fiber raceway system such
as the FiberGuide system must be used for routing the interconnect patch cords to the frame.
Figure 4. Typical Interconnect Application
1.6.2 Cross-Connect Application
In a cross-connect application, both network elements and MPO trunk cables are terminated at
the rear of the frame. A network element may be connected to a trunk cable, a network element
may be connected to another network element, or a trunk cable may be connected to another
trunk cable, using a cross-connect patch cord.
