Perle S-100MM-S2LC80 - Media converter - 100Mb LAN - 100Base-FX, 100Base-ZX - LC multi-mode / LC single-mode - up to 49.7 miles - 1310 nm / 1550 nm

Far-End Fault (FEF). When enabled, the media converter transmits the Far-End Fault indication over the fiber connection whenever a receive failure is detected. The media converter continuously monitors the fiber 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 fiber connection. The action the media converter takes on receiving a Far-End Fault indication is dependent on the link pass-through switch setting. Link pass-through. When enabled, the state of the receiver on one 100Base-X interface is reflected on the other 100Base-X fiber transmitter. If disabled, the 100Base-X fiber interfaces operate independently. Far-End Fault indication on the 100Base-X fiber interface has no effect on the other interface. Using link pass-through with Far-End Fault minimizes 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. Pause (IEEE 802.3xy). Pause signaling 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.
