Congratulations on purchasing a quality UNICOM product.
Unicom’s VELOCITY Series represents the newest, most advanced
generation of signal conversion technology.
Unicom’s Giga Fiber Conver ter is a cost- ef fective solution for the
conversion of 10/100/1000Base-T (Auto MDI/MDIX) and pure 1000
Base-T to 1000Base-SX/LX cabling. It can be slotted into a multiconverter chassis that enhances your network flexibility. It can also be
used as a stand-alone conver ter.
The Giga Fiber Conver ter will allow you to extend the cabling distance of
your 10/100/1000Base-T (Auto MDI/MDIX) or pure 1000 Base-T
network up to 550m for multi-mode fiber or 10 kilometers for singlemode fiber. This Conver ter uses the most popular fiber cabling
connectors: SC multi- mode fiber connector and SC single-mode fiber
connector.
The Modular Giga Fiber Conver ters provides one Fiber connector for fiber
optic cable and one Ethernet RJ-45 port (Auto MDI/MDIX) for
10/100/1000Base-T copper cable or pure 1000 Base-T copper cable
connections. There are DIP- switches to set the operation mode for UTP,
Fiber ports and link lost for warding function.
Dimensions: 120mm x 85mm x 26mm (L x W x H)
Warranty: Limited Lifetime

• Twisted-pair segments can be Unshielded Twisted Pair (UTP) or
Shielded Twisted Pair (STP) cabling. The cable must comply with the
IEEE 802.3 10/100/1000Base-T standard for Category 5e/6. The
cable between the converter and the link partner (switch, hub,
workstation, etc.) must be 100 meters (328 ft.) or less in length.
• Fiber segments using Single Mode connectors must use 9/125µm
Single Mode fiber cable. The maximum link distance in full duplex
operation is 10 Kilometers (6.2 miles). The maximum link distance
in half duplex operation is 412 meters (1352 ft).
• The maximum distance of fiber segments using Multi-Mode
connectors measures 550 meters (1804 ft.) with 50/125µm or
62.5/125µm Multi-Mode fiber cable.
Network Connection
A. Select the appropriate length Categor y 5e or 6 twisted pair cable.
Connect one end of the twisted pair cable to the RJ-45 connector
on the conver ter and the other end of twisted pair cable to the RJ45 connector on any 10/100/1000Base-T device.
B. Connect one end of a fiber jumper to the SC connector on this
converter and the other end of the fiber jumper to the SC
connector on the other 1000Base-SX/LX device.
C. Attach the power adapter DC jack to the conver ter. Verify that the
Power LED is on.
D. Verify that the UTP “LK/ACT” LEDs light when cable connection is
installed correctly. Verify that Fiber “LK/ACT” LED blinks to indicate
network activity.
Troubleshooting
• Verify that you are using the right power adapter, DC 5V, 2A
(minimum). Using a power adapter with DC output greater than 5V
could result in damage to the unit and/or personal injur y.
• Confirm the proper UTP/Fiber cable is being used. The Single Mode
converter must use Single Mode fiber optic cable.

Follow the steps below to install modular conver ters into the 10 space
Converter Chassis (pn: FEP-593110).
A. Remove the blank bracket from the chassis by rotating screw
counterclockwise. Put the blank bracket aside.
B. Open the rack mount bracket kit. The kit contains two rack mount
brackets and four screws.
C. Use a screwdriver to attach the rack mount ears to both sides of
the modular converter.
Hardware Description
The Front Panel
The Front Panel of the 10/100/1000T to 1000SX/LX conver ters
consists of one RJ-45 Por t ( Auto MDI/MDIX ) one fiber 1000BaseSX/LX Port and 6 LED Indicators (SPD, LK/ACT, FDX, Fiber LK/ACT,
FDX/COL and PWR ).
GEP-5300TF-C 550m
D. Install the modular conver ter by inser ting it into the chassis
guides and sliding it in until it stops. Press it firmly to seat the
chassis power plug into the modular conver ter receptacle.
E. Gently push the thumbscrews in and turn clockwise to tighten.
Do not over tighten.

Ports
• Copper Port: RJ-45 Por t (Auto MDI/MDIX), the Ethernet RJ-45 will
features Auto-Sensing for 10/100/1000Base-T connections and
Auto MDI/MDIX which is basically an auto crossover feature. This
means you can connect to another Switch or workstation without
changing to a crossover cable.
• Fiber Port: This por t is for the 1000Base-SX/LX connection and is
available in the SC format in Multi- and Single mode.This fiber por t
does not support auto-negotiation.
The Rear Panel
The rear panel contains a power socket. This power socket accepts
DC9V voltage and minimum 0.7A supplied current.
LED Indicators
DIP Switch Description
There are six diagnostic LEDs located on the front panel of these
converters. The LEDs provide real-time information on system status.
The indicators include SPD, LK/ACT, FDX, Fiber LK/ACT, FDX/COL and
PWR. The following table provides describes these LEDs:
LED Status Color Description
PWR On Green • The converter is supplied with
suitable power.
SPD On Green • Current UTP Speed is 1000Mbps
( speed ) On Amber • Current UTP Speed is 100Mbps
Off -• Current UTP Speed is 10Mbps
LK/ACT On Green • Unit is connected with a link
( UTP ) Blinking -•Unit is transmitting data
Off -•No device attached
FDX ( UTP ) On Orange • The UTP port is in full-duplex mode.
Off -•Half-duplex mode/no device attached
LK/ACT On Green • Unit is connected with a link
( Fiber ) Blinking -•Unit is transmitting data
Off -•No device attached
FDX/COL On Amber • The UTP port is in full-duplex mode
( Fiber ) Off -•No device attached
The DIP-switch is used to configure operation mode for LLF (Link
Lost Forwarding) and operation mode for Copper/Fiber por t. The
default value of Dipswitch is OFF.
10/100/1000Base-T to 1000Base-FX converter module
No. Status Description
1 Off LLF enabled
On LLF disabled
2 Off Switch Cover ter Mode

3 Off Reser ved
On Reserved
Link Lost Forwarding: When LLF is enabled, it will allow copper por t
link failure to be repor ted to the Fiber side and will also allow Fiber
link failure to be repor ted to the copper side. Therefore, a link loss
forward feature is provided on both copper and Fiber sides.
Pure Converter mode: When Pure Conver ter mode is enabled (ON),
the switch operates with the minimum latency. The transmission flow
does not wait until an entire frame is ready but instead for wards the
received data immediately after being received. The TP should be
forced at 1000M in this application.
When the DIP-Switch is in Switch Conver ter mode (OFF), the
converter function is the same as a Switch Hub.
[Note]
1) Do not change the DIP-switch setting when the copper or fiber por t is
transmitting or receiving data. It may cause data error.
2) Power off, then power on when changing the DIP-switch setting.
