Gigabit Fiber Ethernet Converter
10/100/1000Base-T/TX to 1000Base-SX/LX
User’s Manual
Gigabit fiber media converter is a 10/100/1000 auto negotiating media converter. The copper port
auto negotiates the connected device’s speed and duplex mode: 10/100/1000Mbps half duplex;
or 10/100/1000 Mbps full duplex; the fiber port always operates at 1000Mbps. The maximum
distance is Multi-mode 0.5 or 2km and single-mode 10/20/40/60km or 80km.
1. Interface
RJ-45 interface
The transmission media adopts CAT5 twisted-pair with typical length of 100 meter.
It features the function of automatically identifying the through line and cross wire
Fiber interface
Fiber interface is of duplex mode type, including two interfaces, namely TX and RX. When the
two sets of optical transceiver are interfaced or connected to switch with fiber interface, the
fiber is in cross connection, namely "TX-RX", "RX-TX" (direct butting for single optical fiber).
2. Connection
The network device (work station, hub or switch) with RJ-45 interface is connected to RJ-45
jack of the media converter through twisted-pair. The fiber device is connected to fiber
interface of the media converter. Then switch on. The corresponding LED is on for correct
connection. (See the table below for the LED indicator lamp)

1. This product is suitable for indoor application.
2. Put on the dust cover of fiber interface when not used.
3. It is forbidden to stare at the TX fiber-transfer end with naked eyes.
4. Single optical fiber transceiver must be used in pair (See the attachment description in delivery).
Trouble shooting:
1. Device is not matched. Please select the corresponding network device according to the transfer rate of
the product (10Mbps or 100Mbps) when connected to other network devices (network card, hub, switch).
2. Line loss is excessive during the fiber wiring. Excessive loss in connector plug-in and fiber soldering
welding, and excessive intermediate nodes may cause excessive loss rate or abnormal operation.
