the
Fiber Multiplexer

As
a
manufacturer
of
fiber
multiplexers
for
almost
15
years,
our
experience
has
shown
that
in
less
than
1%
of
cases
will
an
operator
ever
use
the
expansion
feature
of
a
modular
multiplexer
which
is
all
E1
or
T1.
This
additional
cost
for
modular
design
is
born
by
the
operator,
increasing
operating
costs.
In
this
age
where
costs
must
be
controlled,
purchasers
should
be
opting
for
a
low
cost
fixed
design
when
available.
Maintenance
personnel
must
take
on
a
new
mind
set
to
not
specify
high
priced
and
useless
features
when
developing
compliance
documents.
Modular
designed
multiplexers,
of
this
capacity,
are
neither
required
or
are
they
financially
viable.
Modular
designs
are
reserved
for
multi
‐
service
multiplexers
supporting
TDM,
Data
and
Voice.

panel
of
the
Fiber Multiplexer
,

channel
and
the

port.
The
optical
interfaces
may
be
of
the
Fixed
type
or
pluggable
SFP
type.
The
two
optical
interfaces
provide
1+1
fiber
protection.
The
front
panel
also
provides
the
connections
to
the
RS

232
Console
Interface
(terminal

and
to
the
