Installation
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 (10/100M).
Fiber interface
SC/ST 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 optical transceiver
through twisted-pair. And the multi/single mode fiber is
connected to SC/ST fiber interface of the optical transceiver.
Then switch on. The corresponding LED is on for correct
connection. (See the table below for the LED indicator lamp)

Explanation for LED indicator lamp
LED indicator lamps serve as device monitoring and trouble
display. The following is the explanation for each LED
indicator lamp.
LED indicator lamp Status Explanation
FX Link/Act On Connection status display for fiber link.
“ON” indicates that Fiber link is
in correct
connection.
Blink Active status display of fiber link
“Blink” indicates packet goes through Fx end.
TX Link/Act On Connection status display for electric link.
“ON” indicates that electric
link is in correct
connection.
Blink Active status display of fiber link
“Blink” indicates packet goes through Tx end.
FDX On Transceiver works in the full duplex mode.
Off Transceiver works in the half duplex mode.
PWR On Power is on and normal.
FX100 On Transfer rate of optical interface is 100Mbps.
TX100 On Transfer rate of electric interface is 100Mbps.
Off Rate of electric interface is 10Mbps

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.
