Equipment and Rear Access Cable Installation

NOTE
:
The optical fiber cable is fragile and must be protected. The fibers should
be placed in a protective tube or channel, such as PVC tubing, or
PANDUIT
cable channel, when running the cable from the DDM-2000 OC-3 to the
cable rack. The fibers should be placed in the cable rack in a protective
channel with nothing on top of them. Cable ties should NOT be used with
the optical fiber cables.
NOTE
:
The mode of fiber (single mode or multimode) that is connected between
the
LGX®
fiber optic distributing frames at each end should be determined.
The fiber from the DDM-2000 OC-3 transmitter to the
LGX®
fiber optic dis-
tributing frame must be single mode or the same mode as exists between
the
LGX®
fiber optic distributing frames. The fiber from the DDM-2000
OC-3 receiver to the
LGX®
fiber optic distributing frame must be multimode
or the same mode as exists between the
LGX®
fiber optic distributing
frames.
NOTE
:
The recommended
PANDUIT
cable channel is listed in the "Introduction"
section of this manual.
!
WARNING:
Unterminated optical connectors may emit laser radiation. Do not view an
unterminated optical connector with optical instruments.
!
WARNING:
Invisible laser radiation when unterminated. Avoid direct exposure of the
eyes to the beam.
NOTE
:
Prior to connecting the optical fiber cables, the fibers should be examined
to ensure that they are clean. The fibers can be cleaned with optical
lint-free tissue or with a compressed air duster.
NOTE
:
The optical fiber cables require
ST®
type connectors for connection to
21G, 21D, and 22F OLIUs only. The 21G-U, 22G-U, 21D-U, and 22D-U
OLIUs can use optical fiber cables equipped with either
ST®
, FC/PC, or SC
type connectors, depending on the type of universal LBO used on the
OLIU. The universal type OLIUs are shipped with a 0 dB
ST®
type univer-
sal LBO installed. If a FC/PC or SC type connector, or a larger LBO is
required it can be ordered separately. See Table 2-18.
