Gigabit Fiber Ethernet Converter
10/100/1000Base-T/TX to 1000Base-SX/LX
User’s Manual
Overview
Gigabit fiber media converter is a 10/100/1000 auto negotiating media converter. The copper port
auto negotiates the connected device’s speed and duplex mode: 10/100/1000Mbps half duplex;
or 10/100/1000 Mbps full duplex; the fiber port always operates at 1000Mbps. The maximum
distance is Multi-mode 0.5 or 2km and single-mode 10/20/40/60/80km or 160km.
There is also 10/100/1000Base-T to SFP (mini-GBIC) media converter available. The SFP slot
supports both Multi-Mode (SX) and Single-Mode (LX) fiber standards for transmission distances
of up to 80km. Gigabit Ethernet port Auto-Negotiate between 100 and 1000Mbps transmission
speeds. Note: DN-82131 support 1000Base-T only.

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
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 the media converter through twisted-pair. The fiber device is connected to fiber
interface of the media converter. Then switch on. The corresponding LED is on for correct
connection. (See the table below for the LED indicator lamp)

Technical parameters:
1. Standard Protocol:
IEEE802.3 10 Base-T standard
IEEE 802.3u 100Base-TX/FX standard
IEEE 802.3z 1000Base-TX/FX standard
2. Connector: one UTP RJ-45 connector, one SC/ST/SFP connector
3. Operation mode: full duplex mode or half duplex mode
4. Environmental temperature: 0°C-60°C
5. Relative humidity: 5%-90%
6. TP cable: Cat5 UTP cable
7. Transfer fiber:
multi-mode: 50/125, 62.5/125 or 100/140μm
single mode: 8.3/125, 8.7/125, 9/125 or 10/125μm

Cautions:
1. This product is suitable for indoor application.
2. Put on the dust cover of fiber interface when not used.
3. It is forbidden to stare at the TX fiber-transfer end with naked eyes.
4. Single optical fiber transceiver must be used in pair (See the attachment description in
delivery). Example: DN-82122 and DN-82123
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.
