Brief introduction
Many thanks for purchasing Gigabit optical converter!
This product supports IEEE802.3Z/AB 1000Base-SX/LX
protocol, the working mode of duplex full mode and half
mode. The electric outlet is adaptive to the rate of
10/100/1000M Gigabit optical converter. This manual is
for various models of adaptive 10Base-T, 100Base-T, and
1000Base-T optical converters. The following purchasing
guide is for customer to refer to.

Installation
1. Interface
RJ-45 interface
The transmission media adopts CAT5 and CAT 6
twisted-pair. It is recommended to use quality RJ-45 and
well made jumper. It features the function of
automatically identifying the through line and cross wire.
Fiber interface
If the SFP fiber transceiver you used is dual fiber type,
including two interfaces namely TX and RX. When the
two sets of optical converter are interfaced or connected
to switchboard with fiber interface, the fiber is in cross
connection, namely "TX-RX" "RX-TX".
2. Connection
Connect the network device (work station, hub or switch)
to the RJ-45 jack of the optical converter through
twisted-pair CAT5. Insert the SFP fiber transceiver in the
metal cage. Connect the multi-mode/single-mode fiber to
the SC/LC fiber interface of the SFP fiber transceiver.
Turn the power on. The corresponding LED is on for a
correct connection. (See the table below for the LED
indicator lamp)

Redundant DIP-Switch description:
When the DIP-Switch is on the "OFF" side (Default), the
2 fiber ports are working on the switch mode; When the
DIP-Switch is on the "ON" side, the 2 fiber ports are
working on the redundant mode.
When the Redundant function enabled, the F1 port work
as main channel, if the F1 port link down, the F2 port will
link up within 10ms, if the F1 port recovered, the F2 port
will link down and F1 link up within 10ms.
