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.

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.
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.

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.
