Product Description

1000Mbps 4 Port Fiber Optic Media Converter Online SFP Module SX/LX Data Buffer 256K
       Media converters can be used anywhere in the network to integrate newer technology with existing equipment to support new applications, technologies and future growth. It provides you SC,FC or ST connectors for your fiber optic cables and RJ45 for twisted pair UTP cable connection. The maximum extension is up to 120km over fiber.Instead of costly, across-the-board upgrades, media converters can extend the productive life of the existing cabling as well as the active equipment.


1. Auto negotiation function allows UTP ports to auto select 10/100/1000M and Full Duplex or Half Duplex.

2. The UTP port supports the connection of MDI/MDI-X auto crossover.

3. Singlemode Fiber: the max distance up to 60km

4. Supporting the max 1536 byte Ethernet packet

5. Supporting flow control

6. Adopting internal power supply

As with any electric device, you should place the equipment where it will not be subject to extreme temperatures, humidity, or electromagnetic interference. Specifically, the site you select should meet the following requirements: Please follow the steps to install the media converter. This Converter is aplug-and-play device.

1. Turn off the power of the device/station in the network in which the media converter will be installed.

2. Ensure that there is no activity in the network.

3. Attach fiber cable from the media converter to the fiber network. The fiber connections must be Matched-Transmit socket to receive socket

4. Attach a UTP cable from the 1000Base-Tx network to the RJ-45 port on the product

5. Connect the power cord to the media converter and check if the power LED lights up. The TP Link and FX link LED will light when all the cable connections are satisfactory.

6. Turn on the power of the device/station.
