T
his easy-to-install, standalone
media converter enables you
to connect your copper network
to a fiber optic segment while
keeping data flowing at Gigabit
Ethernet speeds.
Compact enough to fit on
the desktop and made of durable
sheet metal, the B ACK BOX
®
ayer 1 Gigabit Media Converter
provides seamless 1000BASE-TX
to 1000BASE-SX or 1000BASE- X
conversion. We offer two models:
the G5134A-R3 for connecting to
850-nm multimode fiber; and the
GC5135A-R3 that supports 1300-
nm single-mode connections.
In the electrical-to-optical
conversion, the media converter
bridges the gap between copper
and fiber optic wiring systems. It
not only brings fiber to the desktop
user but offers access to fiber-
based services for the enterprise.
Use the ayer 1 Gigabit Media
Converter, for instance, to share
your legacy network equipment
and wiring with today’s newer
technologies without having to
undertake a costly upgrade.
Make twisted-pair to fiber conversions
in your Gigabit Ethernet network.
LAYER1GIGABITMEDIACONVERTERS
By supporting Gigabit Ethernet
speeds, the media converter not
only brings greater bandwidth to
your network, but it gives you an
easy way to connect an enterprise
backbone with a more-demanding
metropolitan area network (MAN)
or wide area network (WAN). With
the converter, enterprise and
service provider networks can
deliver speeds of 1.25 Gbps* over
both copper and fiber optic cabling
infrastructures.
What’s more, with a ayer 1
Gigabit Media Converter, you can
extend the reach of your Gigabit
Ethernet greater distances—up
to 40 kilometers (24.9 miles) with
the single-mode GC5135A-R3
model!—while using standard
1000BASE-T switch ports at both
ends of your fiber run. This way,
you can keep using your twisted-
pair cable plant on your local side
and connect an optical switch to
your network.
The GC5134A-R3 operates
across distances of up to 200
meters (656.2 ft.) on multimode
fiber optic cable.
Because the box performs
its conversions at ayer 1 (the
Physical ayer), the device is
transparent to the network’s
higher-level protocols. In addition,
there’s no bulky external power
transformer to make installation
of the ayer 1 Gigabit Media
Converter cumbersome; the
device has a built-in universal
power supply.
And you won‘t need any
crossover cables for the twisted-
pair side. You can get away with
using just straight-through cabling
to connect your copper devices.
That’s because the converter has
an MDI/MDIX function that
automatically determines whether
the converter has to cross over
between the four pairs on the
1000BASE-TX port’s RJ-45
connector.
The media converter uses
autonegotiation to configure
each of its ports for full- or half-
duplex and master or slave
modes of operation. It does this
by determining which clock will be
used between the media converter

and its connected device, whether
it’s a switch, a network interface
card (NIC), or another ayer 1
Gigabit Media Converter. To avoid
conflicts with devices connected
to the media converter, it senses
which mode is appropriate and
chooses either slave or master
mode.
To override the factory
defaults of duplex settings and
slave/master modes, you need
only to change an 8-position
DIP switch on the bottom of the
converter box and activate the
front-panel reset button.
Fault-detection features
The ayer 1 Gigabit Media
Converter has ink Integrity
features that prevent “silent
failures” on your network. What
this means is that the converter
identifies lost cable links. No more
time wasted searching for them! A
link can be checked by physically
observing the status of the media
converter’s ink ED.
One feature, FiberAlert™,
signals to you when a fault occurs
on one fiber strand and the link is,
in turn, incapable of carrying
bidirectional communications
between two fiber devices. If
a strand isn’t available and
you have FiberAlert enabled, the
device at the receiver end notes
the loss of the link and stops
transmitting data until it receives
a signal or link pulse.
Essentially, with FiberAlert, the
link status of one end is mirrored at
the opposite end. This means that
the link status can be seen at both
en s through the respective ink
EDs, thus helping you to identify
and isolate faults anywhere in the
fiber loop. FiberAlert works even if
the fiber devices are separated by
great distances.
ink oss™ is a feature that‘s
similar to FiberAlert in that faults
on one port are mirrored on the
other. But in the case of ink oss,
a fault on the fiber port is mirrored
to an Ethernet twisted-pair port
rather than another fiber port.
So if the fiber link is lost at the
converter, the converter disables
the twisted-pair ink ED. With
ink oss enabled, the link status
of the fiber segment will always
be reflected by the twisted-pair
segment so you’re informed
quickly of fiber problems.
LEDs show activity, signal alerts
All selectable features on the
ayer 1 Gigabit Media Converter
are externally accessible, and
each port includes diagnostic
EDs for easy monitoring of
activity on both connected cable
segments. In all, the box has seven
EDs on its faceplate—four to the
right of the shielded RJ-45 UTP
jack and three to the right of the
fiber optic SC connectors.
The first set of EDs signal
when data is detected on the
twisted-pair port, when you
establish a twisted-pair link,
when it’s operating in full-duplex
mode, and when the unit has
power.
The second ED set informs
you when the converter detects
data on the fiber port, when you
establish a fiber link, and when
FiberAlert is enabled.
