Packing List
When you unpack this product package, you will find the
items listed below:

Fiber Switch 1 piece
AC/DC5V1A Adapter 1 piece
Copy of user manual 1 piece
Installation
1. Interface
RJ-45 Interface
RJ-45 Connector supports CAT5 twisted-pair with typical
length of 100 meters. It features the function of
MDI-MDIX through parallel lines.
Fiber Interface
SC/ST fiber interface is of 100M full-duplex mode,dual
fiber(TX and RX)should be cross-connected(TX-RX,
RX-TX),direct connection for single optical fiber when
the transmitter and receiver are interfaced or connected
to switch with fiber interface.
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
multimode/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)
