PoE PSE Media Converter not only connects
100BASE-FX fiber to 10BASE-T/100BASE-TX copper, but it also
functions as power source equipment (PSE) in Power over
Ethernet (PoE) applications.
PoE enables you to provide power over the spare pairs
of an Ethernet data cable to compatible PoE-powered devices
(PDs). These can be wireless access points, CCTV security cameras,
or VoIP phones. The PoE PSE Media Converter works as an
endpoint PSE that delivers -48-VDC power via twisted-pair
cable Pins 1, 2, 3, and 6.
Using a single cable to deliver both data and power gives
you added flexibility. It’s particularly beneficial in areas where
you’re short on AC power outlets, and it eliminates the need
to run separate AC power circuits to devices at the edge of
your LAN.
In a typical PoE application, you’d use the PoE PSE Media
Converter to convert copper and fiber in order to extend your
data runs at long distances over interference-free, signalenhancing optical cable. Then, at the end of the fiber run,
you would use a remote management PC or security station to
communicate with the PoE devices plugged into the converter.
The converter gets its power from an autosensing AC power
supply that plugs into a standard outlet.
Compatible with the 802.3af PoE standard, the PoE PSE
Media Converter features an advanced autosensing algorithm
that enables it to provide PDs with discovery, classification,
current limit, and other necessary functions.
For PoE-side PD links, simply run a twisted-pair cable to
compatible equipment. The converter supports 10BASE-T
or 100BASE-TX media. Or set it up to adapt to the speed of
the Ethernet or Fast Ethernet connection, and use it in an
existing switch, bridge, or router application.
The media converter offers overcurrent and undercurrent
detection, as well as fault protection input and power
monitoring. LEDs inform you if PoE feeding power is
disrupted and the class of PD connected (4-W Class 1, 7-W
Class 2, or 15.4-W Class 0 or 3 device). PD signature sensing
detects when a 802.3af-compliant PD is connected
downstream. This helps protect non-802.3af legacy devices
that may be accidentally connected to the converter.
On the fiber side, the media converter connects to
1310-nm 100BASE-FX media. Depending on the model
you order, this can be multimode fiber optic cable with ST
or SC type connectors or single-mode cable terminated with
SC type connectors. The multimode PoE PSE Media Converter
models support full duplex fiber runs up to 2 kilometers
(1.2 mi.) long, and the single-mode model supports
full duplex fiber segments as far as 20 kilometers (12.4 mi.).
Link-fault passthrough and far-end fault detection keep
you from sending valuable data across invalid links. Link
status on one port is propagated to the other port. If either
the twisted-pair or the fiber optic port is in link-fail state—
if it’s unplugged, for instance— the converter disables the
other port, thus passing through the link fault. The converter
also stops sending link pulse to the link partner if it detects
loss of a fiber RX signal.
Rear-panel DIP switches enable you to configure the
converter quickly so you’re up and running in a matter
of minutes. Simply ensure that connected nodes are set to
operate in flow control mode identical to that of the media
converter. No further intervention is required.
And though it’s designed to work as a PoE PD, the PoE
converter doesn‘t have to be used this way. It also works as
a pure converter. It’s even ideal for temporary setups where
you need to convert copper twisted-pair interfaces to fiber
media, and vice versa.

Recognize any of these situations?
• You wait more than 30 minutes to get through
to a vendor’s tech support.
• The so-called “tech” can’t help you or gives you
the wrong answer.
• You don’t have a purchase order number and the
tech refuses to help you.
• It’s 9 p. m. and you need help, but your vendor’s
tech support line is closed.
According to a survey by Data Communications
magazine, 90% of network managers surveyed say
that getting the technical support they need is extremely
important when choosing a vendor. But even though
network managers pay anywhere from 10 to 20% of their
overall purchase price for a basic service and support
contract, the technical support and service they receive
falls far short of their expectations— and certainly isn’t
worth what they paid.
At Black Box, we guarantee the best value and the
best support. You can even consult our Technical Support
Experts before you buy if you need help selecting just
the right component for your application.

Power over Ethernet (PoE) provides a way for network
devices to be powered by their data cables rather than by
separate power cords. The IEEE 802.3af PoE standard calls
for 48 volts of AC power over any grade of UTP wire,
including Category 3, 5, 5e, and 6. The specification covers
power sourcing equipment (PSE) and powered devices (PDs).
The PSE puts power onto the UTP cable, and the PD
picks it off.
How does PoE work? Very simply, Ethernet cable consists
of four twisted pairs of cable: two pairs for data transmission
and two “free” pairs that can be used for other purposes.
802.3af PoE uses either the spare pairs or the data pairs
to transmit power. It adds DC power to the wires using signal
transformers and picks off power at the far end the same way.
Although sending power over the data pairs rather than
the spare pairs would seem to be counterintuitive, data and
power transmissions don’t interfere with each other because
they’re at opposite ends of the frequency spectrum.
Specifically, electricity has a low frequency of 60 Hz or less,
and data transmissions have frequencies that can range
from 10 million to 100 million Hz.
The 802.3af standard calls for the maximum power
available to any powered device to be 12.95 watts with a
voltage range of 36 VDC to 57 VDC. This is more than enough
to power typical PoE devices, such as wireless access points.
