1. Overview
Thank you for purchasing Antaira's FCU-1802Px family of
10/100Mbps Ethernet Twisted pair to 100Base-FX Fiber-optic
PoE Bridge Converter. This converter is used to convert one type
media signal to another easily, efciently and inexpensively. The
converter provides Power over Ethernet power injector function
which is able to drive one IEEE 802.3af compliant powered
devices.
About the Power over Ethernet Injector
The FCU-1802Px has an IEEE 802.3af Power over Ethernet
Injector that provides DC 48V over Ethernet cables. The
FCU-1802Px IEEE 802.3af Power over Ethernet Injector inserts
DC Voltage into Cat.5 cable, allowing the cable between the
Injector (FCU-1802Px) and PoE PD (Powered Device) to transfer
data and power simultaneously. The maximum distance between
the Injector (FCU-1802Px) and PoE PD is 100 meters. With
the FCU-1802Px installed, it combines the Ethernet digital data
with power over the twisted pair cables as an IEEE 802.3af
Power over Ethernet Injector. And the IEEE 802.3af Power over
Ethernet splitter shall separate the digital data and the power
into two outputs.
With IEEE 802.3af Power over Ethernet devices installed, the
system administrator only has to use a single RJ-45 Ethernet
cable to carriy both power and data to each device. Aside from
connecting through the FCU-1802Px and PoE PD, you can also
have the benet of cost saving, easy for networking planning,
and higher reliability. Moreover, upon any IEEE 802.3af device
installation, the FCU-1802Px or PD can make the connection
while migrating the Ethernet digital packets, such as connecting
the FCU-1802Px to an IEEE 802.3af complied devices, AP or IP
Camera.

4. Link Fault Pass through (LFP)
The LFP function includes the Link Fault Pass Through
function (LLCF/LLR) and the DIP Switch design. LLCF/LLR can
immediately alert administrators about problems with the link
media and provide an efcient solution to monitor the net. The
DIP Switch can disable or enable the LFP function.
With LLCF (Link Loss Carry Forward), when a device connected
to the converter loses the TP line link, the converter’s ber will
disconnect the link of transmit. With LLR (Link Loss Return),
when a device connected to the converter and loses the ber
line link, the converter’s ber will disconnect the link of transmit.
Both can immediately alert administrators about link media
problems and provide an efcient solution to monitor the net.
Link Loss Carry Forward (LLCF)
The FCU-1802Px incorporates an LLCF function for
troubleshooting a remote connection. When LFP function is
enabled, the FL/TP ports do not transmit a link signal until they
receive a link signal from the opposite port.
The diagram below shows a typical network conguration with a
good link status using the FCU-1802Px for remote connectivity.

Link Loss Return (LLR)
The ber ports of the FCU-1802Px have been designed with an
LLR function for troubleshooting a remote connection. LLR works
in conjunction with LLCF.
When LFP function is enabled, the port’s transmitter shuts down
when its receiver fails to detect a valid receive link. LLR should
only be enabled on one end of the link and is typically enabled
on either the unmanaged or remote device.
The diagram below shows a typical network conguration with a
good link status using the FCU-1802Px for remote connectivity.
Note that LLR and LLCF are enabled as indicated in the diagram.

If one of the optical conductors is bad (as shown in the diagram
box below), the converter with LLR function will return a no-link
condition to its link partner. With LLCF function also enabled,
the no-link condition is carried forward to the switch/hub
where a trap is generated to the management station, and the
administrator can then determine the source of the loss.

If you are familiar with the network installa-
tion, for diagnostic purpose (i.e. check which
end is broken), you can turn it off and reset the
converter to make it take effect. Otherwise, please
leave it at the default position.

FCU-1802Px and the IEEE 802.3af Injector / Splitter
equipment installation:
Before your installation, it is recommended to check your
network environment. If there is any IEEE 802.3af devices that
need to power on, the FCU-1802Px can provide a way to supply
power for this Ethernet device conveniently and easily. The
FCU-1802Px comes with an AC-DC adapter with DC 48V input
and injects this DC power into the pin of the twisted pair cable
(pair 1, 2 and pair 3, 6).
