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
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)
