FSP 3000R7 ROADM-C40/40/2-3HU-2DC and FSP 3000R7 Optical Cabling
,
which describes how to establish optical connections between the FSP 3000R7
master shelf supporting modules and ROADM-C40/40/2-3HU-2DC shelves.
Introduction
Due to system flexibility, planning and designing individual configurations is
quite complex. FSP Network Planner should be used as an aid for planning, cal-
culation, and installation of your custom tailored configuration. See the
FSP Net-
work Planner User Manual
.
Fiber optic cabling is carried out during network element (NE) installation.
Pairs of fiber-optic jumpers are used to connect various optical modules
installed in a single FSP 3000R7 equipment shelf and within the NE (inter-shelf
connections). The equipment shelves may come with preterminated fiber optic
cabling according to the system configuration ordered. In this case, only the
completely pre-installed equipment shelves, ROADM Shelves, 1HU passive
shelves, and fiber management shelves of a NE need to be interconnected opti-
cally.
The interconnection requirements are determined by your system configuration
and can be found in the optical cabling plan. The ports of the optical modules
are connected with respect to their logical sequence in the network. Optical con-
nections are established from client lines (CPE) via channel modules, various
active or passive optical modules, amplifiers, an optical switch module through
to the network line. In this way the fiber-optic jumpers form the internal optical
signal path of a single network element.
Labeling the optical connectors on the faceplate of each module is explained in
the
Hardware Description
.
Pairs of connecterized fiber-optic jumpers of different lengths and types are
delivered with each equipment shelf. They are color coded and labeled accord-
ing to usage.
Fiber optic jumpers can easily be damaged if they are improperly handled and
installed. It is imperative that all guidelines for the proper handling of optical
fibers and the standard installation parctices for field use be followed.
Optical module ports (receptacles) and fiber-optic connectors are susceptible to
become contaminated.The fiber end face and ferrule of the fiber optic connec-
tors must be absolutely clean and smooth, and must not display scratches or
cracks to achieve correct fiber connections. Microscopic dust particles, finger
crease or any other loose contaminants on the fiber end faces can cause a num-
ber of performance problems in optical networking if contamination is not com-
pletely removed prior to first or any mating the connectors. Mating a dirty
fiber-optic connector can cross-contaminate the receptacle of the module and/or
can permanently damage both end faces of the fibers. Consequently, the two
mated connectors have to be replaced. Therefore, please remember that visual
inspection, cleaning and re-inspection of the fiber optic connectors are
all-important steps which must be performed before you make any fiber-optic
connection. Even brand new fiber-optic connector and receptacles needs to be
