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. Fiber
interface LC is of duplex mode type, including two interfaces, namely TX and RX.
When the two sets of optical transceivers are interfaced or connected to switch, 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 this converter through a twisted pair. And the multi/single mode fiber is
connected to fiber interface of this converter. Then optical transceiver works. The
corresponding LED is ON for correct connection. (See the table below for the LED
indicators.)
Explanation for LED indicator lamp
LED indicators serve as device monitoring and trouble display. The following is the
explanation for each LED indicator.
LED
Status
Explanation

Trouble shooting:
1. Device is not matched. Please select the corresponding network device according to
the transfer rate of the product (10Mbps or 100Mbps, 1000Mbps) 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, and excessive intermediate nodes may cause excessive loss rate or
abnormal operation.
