❖Item : SFP Port
SFP Transceiver Module
You can select different SFP modules as required (Please refer to our SFP selection list for the
appropriate module). To insert/remove the SFP, the procedures are as follow:
1. On the side panel, insert the SFP module into the SFP port until it is securely locked.
2. Connect the optical fiber (1/2 core) to the LC connector(s) of the SFP.
3. To remove the SFP module, press down the lock of the LC connector of the optical fiber to pull
out the fiber cable.
4. Pull down the SFP lever and hold its position. Pull out the SFP module from the SFP port.
User Manual
Notes: If you make your own cable, we suggest
labeling the two sides of the same line with the
same letter (A-to-A and B-to-B, shown as below, or
A1-to-A2 and B1-to-B2).

Setup
a) Connect the Ethernet port of the media converter to a PC or network device with a
network cable.
b) Insert the appropriate SFP into the corresponding SFP port. Connect the fiber cable from
the remote device (media converter or switch) to the LC connector of the SFP.
c) After the device is powered on, the PWR indicator will all be on. If the indicators are not
on, check the power supply connection.
d) After all cables are correctly connected, the indicators will be lit as per port status LEDs .

❖Drawing
As aforementioned, an Ethernet crossover cable is adopted to connect two ports of
the same configuration (i.e. MDI-to-MDI or MDIX-to-MDIX). However, it may generate
some confusion and inconveniences when deploying two different kinds of Ethernet
cables. The auto-MDI/MDIX technology is developed to fix this problem: It
automatically switches between MDI and MDIX as required. Auto MDI/MDIX ports on
newer device interfaces detect if the connection requires a crossover, then
automatically choose the MDI or MDIX configuration to properly match the other end
of the link. In this case, it doesn’t matter if you using straight through or crossover
cables. The chart below shows cable types for MDI/MDIX and auto-MDIX.

Wiring Requirements
Cable laying need to meet the following requirements,
1. It is needed to check whether the type, quantity and specification of cable
match the requirement before cable laying;
2. It is needed to check the cable is damaged or not, factory records and quality
assurance booklet before cable laying;
3. The required cable specification, quantity, direction and laying position need to
match construction requirements, and cable length depends on actual position;
4. All the cable cannot have break-down and terminal in the middle;
5. Cables should be straight in the hallways and turning;
6. Cable should be straight in the groove, and cannot beyond the groove in case
of holding back the inlet and outlet holes. Cables should be banded and fixed
when they are out of the groove;
7. User cable should be separated from the power lines. Cables, power lines and grounding
lines cannot be overlapped and mixed when they are in the same groove road. When
cable is too long, it cannot hold down other cable, but structure in the middle of alignment
rack;
8. Pigtail cannot be tied and swerved as less as possible. Swerving radius cannot be too small
(small swerving causes terrible loss of link). Its banding should be moderate, not too tight,
and should be separated from other cables;
9. It should have corresponding simple signal at both sides of the cable for maintaining.
❖Installation
Before installation, confirm that the work environment meet the installation
require, including the power needs and abundant space. Whether it is close to the
connection equipment and other equipment are prepared or not.
1. Avoid in the sunshine, keep away from the heat fountainhead or the area
where in intense EMI.
2. Examine the cables and plugs that installation requirements.
3. Examine whether the cables be seemly or not (less than 100m) according to
reasonable scheme.
4. Power: 12-48VDC power input
5. Environment:
working temperature: -40～75℃
Storage Temperature: -40～85℃
Relative humidity 5%～95%
Assembly, Startup, and Dismantling
• Installation: Mount the Micro type unit onto a fixture, or camera housings, e.g.
a plank, (either on the wall or on a flat surface) with at least 2 screws piercing
through the holes on the mounting frame to secure it in position.
• Startup: Connect the supply voltage to start up the Media Converter via the
terminal block.
• Dismantling: Locate and remove the securing screws. Usually, but not limited
to, at least 2 screws.
