Perle's advanced features make the end to end fibre link completely transparent. This allows for more efficient troubleshooting and less on-site maintenance. In addition, a lifetime warranty and free worldwide technical support make Perle's S-100MM Fast Ethernet Fibre to Fibre Media Converters the smart choice for IT professionals.

Whether you need to extend multimode to multimode or multimode to single mode, Perle has an extensive range of S-100MM Fast Ethernet Fibre to Fibre Media Converters to meet your fibre conversion requirement.

Link Pass-Through

When enabled, the state of the receiver on one 100Base-X interface is reflected on the other 100Base-X fibre transmitter. If disabled, the 100Base-X fibre interfaces operate independently. Far-End Fault indication on the 100Base-X fibre interface has no effect on the other interface. Using Link Pass-Through with Far-End Fault minimises data loss when a fault occurs. If a fault occurs, the end devices have the indication of a failure available to making trouble shooting easier.

Far-End Fault (FEF)

When enabled, the media converter transmits the Far-End Fault Indication over the fibre connection whenever a receive failure is detected. The media converter continuously monitors the fibre connection and clears the Far-End Fault Indication condition when a valid signal is received. When disabled, Far-End Fault Indications are not transmitted regardless of the condition of the receive signal on the 100Base-X fibre connection. The action the media converter takes on receiving a Far-End Fault Indication is dependent on the Link Pass-Through switch setting.

Signal Regeneration

Signal regeneration maintains signal integrity and allows for maximum fibre to fibre connections without degradation.


Media converters can be cascaded. Two or more media converters can be chained in a link to achieve even greater distances.

Pause (IEEE 802.3xy)

Pause signalling is an IEEE feature that temporarily suspends data transmission between two devices in the event that one of the devices becomes overwhelmed. The fast ethernet media converter supports pause negotiation on the 100Base-TX copper connection.


The media converter is transparent to VLAN tagged packets.

Remote Loopback

The media converter can perform a loopback on each 100Base-X fibre interface.
