Perle SMI-100-S2LC40 - Fiber media converter - 100Mb LAN - 100Base-TX, 100Base-EX - RJ-45 / LC single-mode - up to 24.9 miles - 1310 nm

Link pass-through. With link pass-through the state of the 100 Base-TX receiver is passed to the 100 Base-FX transmitter to make the media converter appear transparent to the end devices that are connected. In addition if Far-End Fault is enabled the media converter can turn off the 100 Base-TX transmitter when a Far-End Fault is received. Using link pass-through with Far-End Fault minimizes data loss when a fault occurs. Should a fault occur, the end devices have the indication of a failure available to them 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 100 Base-TX copper connection. Auto-MDIX. Auto-MDIX detects the signaling on the 100 Base-TX interface to determine the type of cable connected and automatically configures the connection when enabled. With auto-MDIX enabled, either a straight-through or crossover type cable can be used to connect the media converter to the device on the other end of the cable. Far-End Fault (FEF). The media converter implements the 802.3 standard for Far-End Fault for the indication and detection of remote fault conditions on the 100Base-FX fiber connection. With Far-End Fault enabled the media converter transmits the Far-End Fault Indication over the 100Base-FX fiber connection whenever a receive failure is detected on the 100Base-FX fiber connection. The media converter continuously monitors the100Base-FX fiber connection for a valid signal.
