3 WDM MOUNTING PROCEDURE (OPTIONAL ACCESSORY)
A
bi-directional
wavelength
division
multiplexer
(WDM)
is
available
as
an
accessory
item
for
non-diversity
versions
of
the
Digivance
LRCS.
If
the
application
does
not
require
the
use
of
a
WDM,
skip
this
section
and
proceed
to
Section
4.
The
version
of
the
WDM
that
is
used
with
the
HU
consists
of
one
or
two
WDM
modules
and
a
WDM
mounting
shelf.
Each
WDM
module
can
support
two
HU’s
and
each
WDM
mounting
shelf
can
hold
two
WDM
modules.
A
fully
loaded
WDM
mounting
shelf
can
therefore
support
four
HU’s.
When
multiple
HU’s
require
connection
to
a
WDM,
the
WDM
mounting
shelf
and
the
HU’s
should
be
mounted
in
the
equipment
rack
as
shown
in
Figure 3-2.
This
configuration
allows
the
pigtail
leads
from
the
two
WDM
modules
to
be
connected
directly
to
the
optical
ports
on
any
one
of
the
four
HU’s.
Figure 3-2. Typical WDM and HU Configuration
The
WDM
mounting
shelf
may
be
mounted
in
either
a
19-inch
or
23-inch
EIA
or
WECO
equipment
rack.
Four
#12-24
screws
are
provided
for
securing
the
mounting
shelf
to
the
rack.
Use
the
following
procedure
to
install
the
WDM
mounting
shelf
in
the
equipment
rack
and
to
mount
the
WDM
modules
in
the
WDM
mounting
shelf:
1. The
WDM
mounting
shelf
is
shipped
with
the
mounting
brackets
installed
for
19-inch
EIA
rack
installations.
If
installing
the
mounting
shelf
in
a
19-inch
EIA
rack,
proceed
to
step
5.
If
installing
the
mounting
shelf
in
a
19-inch
WECO
rack,
a
23-inch
EIA
rack,
or
a
23-inch
WECO
rack,
proceed
to
step
2.
