Convertidor Fast Ethernet ROLINE RC-100FX/ST

The ROLINE RC-100FX/ST Fast Ethernet Converter provides media conversion between STP (shielded twisted pair) and multimode ST fiber, enabling connection of RJ-45 Ethernet devices to ST fiber links. It supports 100 Mbit/s data transfer, includes a loop-back test feature for diagnostics, and is powered via the supplied external power adapter. The compact grey housing measures 72.5 x 108 x 23 mm.

Advantages

This converter allows seamless conversion from RJ-45 to ST multimode fiber, supporting mixed cabling environments that combine shielded copper and fiber optic segments. It supports a maximum fiber reach of up to 2000 m when used with 50/125 µm multimode fiber and provides a built-in loop-back for simple testing and troubleshooting. The unit is powered by the included 7.5 V DC, 500 mA external power supply.

Suitable for

• Extending 100 Mbit/s Ethernet networks over multimode ST fiber
• Connecting RJ-45 devices to ST fiber infrastructure
• Mixed cabling environments combining STP copper and multimode fiber
• Basic network testing and troubleshooting using the loop-back feature

How to use

Connect the RJ-45 Ethernet cable from your network device to the converter's LAN port and attach the ST multimode fiber cable to the ST fiber connector. Plug the supplied 7.5 V DC, 500 mA power adapter into the unit and an electrical outlet. Verify link/activity indicators on connected devices and use the loop-back feature if you need to perform a basic continuity or diagnostic test.

Recommendations

Use 50/125 µm multimode ST fiber to achieve the stated maximum distance of up to 2000 m. Ensure proper handling and cleaning of ST connectors to maintain signal quality. Place the converter in a dry, ventilated location and avoid exposing it to extreme temperatures or moisture.
