Installation
Connect the fiber network cable to the LC connector on1.
the fiber media converter. Using UTP Ethernet cable,
connect the cable to the RJ45 jack.
Set the Auto/Force switch on the media converter, to2.
turn auto negotiate on or off. If set to Force, set the
Duplex switch (full/half) according to the specifications
of your networking equipment.

DIP Switch Conguration
Full/ Half:
The Fiber and UTP Duplex will be configured in Full
duplex or Half duplex.
This switch includes an “Auto Reset” function so the*
power-reset is not necessary when any modification is
made here.
LBT:
Loop-back test and get remote side status :
(OFF = Not Active, ON = Active).
If the local side loop-back test is active, then LEDs*
(except PWR) will all blink rapidly and refresh to display
the remote side status.
LLF:
Link Loss Forwarding (OFF = Not active, On = Active)
Auto/Force:
Auto negotiate duplex mode, or force Full/Half via DIP
switches.

Loop-back Testing (LBT) & Get CPE status
This fiber media converter incorporates a Fiber Loop-
back Testing feature which allows the system to confirm
whether or not the fiber or Ethernet circuit loop is
complete. The local-side unit will send out a detect
message which includes both command and test-pattern
data to the remote-side unit and request for an answer.
When the remote-side unit receives the message, it will
attempt to recognize the command.
After the remote-side unit recognizes the command
message, it will deliver the received test-pattern data
back to the local-side unit, completing the circuit loop, and
enabling the rack mount unit to easily monitor the remote
side unit(s). The remote side status message includes
the fiber-side link and duplex status, the UTP-side link,
duplex, speed, power, transmission and fiber failure
status.
Please note that while Loop-back testing is in process,
the fiber side transmission will be halted. If the local-side
cannot access the remote-side while in Loop-back Testing
mode, only the power LED will flash (rapidly):
Link-Loss-Forwarding (LLF)
This fiber media converter incorporates a Fiber Link
Forwarding feature that allows indirect sensing of a
Fiber Link Loss via the 1000 Base-TX UTP connection.
Whenever the media device detects a Link Loss on
the Receive fiber (Fiber Link OFF), it disables its UTP
transmitter so that a Link Loss condition will be sensed
on the receive UTP port (as depicted in the following
diagram). The Link Loss can then be easily monitored and
reported at the remote UTP port’s host equipment.
This feature has no effect on the media converter’s
UTP Link LED, which continues to function normally,
independent of the state of the Fiber Link LED and the
UTP transmitter. This feature is enabled by default.
