Fast Ethernet Media Converter

The Perle 05050204 is a stand-alone Fast Ethernet media converter that connects 10/100Base-TX copper to 100Base-FX fiber. It extends network links up to 1.24 Mile over multimode ST duplex cabling. Network administrators use it to bridge legacy copper gear with fiber infrastructure without replacing switches or endpoints.

Plug-and-play installation

The unit requires no software configuration; simply insert the RJ-45 and ST duplex connections and apply power with the included US cord. Its compact 1.0 by 3.1 by 4.7 inch footprint fits on a desk or shelf. The only common issue is mismatching the fiber type or exceeding the 1.24 Mile distance limit, which causes link failure.

Sustained link stability

Under continuous traffic the converter maintains line-rate Fast Ethernet throughput without packet loss. It operates silently with no moving parts and handles extended uptime in temperature-controlled environments. The metal enclosure aids passive heat dissipation during 24/7 operation.

Questions about this item

How can I verify the 100Base-FX link is active after connecting the ST duplex fiber?

Check the LED indicators on the converter for a solid link light on the fiber port and confirm 100 Mbps full-duplex status in your switch management interface.

Does the package include the fiber patch cable for the ST duplex port or must I order it separately?

The box contains the media converter and a US power cord only; an ST duplex fiber patch cable is not included and must be purchased separately.

Which model should I select if I need to bridge 10/100Base-TX copper to 100Base-FX multimode fiber up to 1.24 miles?

Choose the 05050204 (S-100-M2ST2) — it provides one RJ-45 port and one ST duplex port rated for 1.24 mile multimode reach.
