Revision
User’s manual for Antaira 100Base-FX to 10/100Base-TX PoE Media Converter
Rev 1.1 (April 2013)
Part No. 2350-AA3540-470
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 of media signal to another easily, efficiently, and
inexpensively. The converter provides Power over Ethernet power injector
function which is able to drive one IEEE 802.3af compliant powered device.
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 benefit 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.

- User’s Manual x 1
- If any items are missing or damaged, please consult the dealer from which you purchased your PoE Media Converter.
Product Outlook
Overview
The layout of the FCU-1802Px.
Left View
There is one RJ-45 Twisted-Pair jack (Auto-MDI/MDI-X), one fiber-optic
connector (vary by model) and four LED indicators.
Right View
One DIP switch for Link Fault Pass Through (LFP) feature, “ON” to turn-on the
LLCF and LLR detection. And “OFF” to turn off this feature. Please refer to
the following sections for more. Also one DC 48V power socket for the PoE
Media Converter.
Link Fault Pass-through (LFP)
The LFP function includes the Link Fault Pass Through function (LLCF/LLR) and
the DIP Switch design. LLC/LLR can immediately alert administrators about
problems with the link media and provide an efficient 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 fiber will disconnect the link of
transmitting. With LLR (Link Loss Return), when a device is connected to the
converter and loses the fiber line link, the converter’s fiber will disconnect
the link of transmitting. Both can immediately alert administrators about link
media problems and provide an efficient solution to monitor the net.
Link Loss Carry Forward (LLCF)
The FCU-1802Px incorporates an LLCF function for troubleshooting a remote
connection. When the 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 configuration with a good link
status using the FCU-1802Px for remote connectivity.
If the connection breaks, the FCU-1802Px link loss forwards to the switch/hub
which generates a trap to the management station. The administrator can then
determine the source of the problem.
*Units are shipped with the LFP function disable (OFF).
Link Loss Return (LLR)
The fiber ports of the FCU-1802Px have been designed with an LLR function for
troubleshooting a remote connection. LLR works in conjunction with LLC.
When the 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 configuration 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 the LLR function will return a no-link condition to its
link partner. With LLC 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. Note
The LFP function is turned on by default. This feature can also be turned off
via the side DIP switch. If you are familiar with the network installation,
for diagnostic purposes (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.
Installing the Converter
Please follow these steps to install the PoE Media converter:
-
Turn off the power of the device/station on the network to which the FCU-1802Px will be attached.
-
Ensure that there is no activity in the network.
-
Attach fiber cable from the FCU-1802Px to the fiber network. TX and RX must be paired at both ends. Attach a Cat. 5 UTP cable from the 10/100Base-TX network to
the RJ-45 port on the FCU-1802Px. -
Connect the 48V DC power adapter to the FCU-1802Px and verify that the Power LED is lit.
-
Turn on the power of the device/station, and the TX Link, and FX Link LEDs should light when all cables are attached.
Note
RJ-45/STP, UTP Cat 5, straight /crossover cable is accepted.
Please refer to section 9 for more about the wiring distance of your TP,
Optic-fiber networks.
PoE function
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).
