PERLE SYSTEMS 05081254 Perle S-1110PP-M2ST2 - Fiber media converter - GigE - 10Base-T, 1000Base-LX, 100Base-TX, 1000Base-T - RJ-45 / ST multi-mode - up to 1.2 miles - 1310 nm

Auto-MDIX. Auto-MDIX (automatic medium-dependant interface crossover) detects the signaling on the copper Ethernet interface to determine the type of cable connected and automatically configures the connection when enabled. The media converter can also correct for wires swapped within a pair. 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 media converter supports pause negotiation on the 10/100/1000BASE-T connection and 1000BASE-X fiber connection. Auto-negotiation (802.3u). The media converter supports auto negotiation. The 1000BASE-X fiber interface negotiates according to 802.3 clause 37. The 10/100/1000BASE-T negotiates according to 802.3 clause 28 and 40. The 1000BASE-X can link up with its partner after the high common denominator (HCD) is reached and the copper has linked up with its partner. The 1000BASE-X can continue to cycle through negotiation transmitting a remote fault of offline until the copper is linked up and the HCDs match. Fiber fault alert. With fiber fault alert the state of the 1000BASE-X receiver is passed to the 1000BASE-X transmitter. This provides fault notification to the partner device attached to the 1000BASE-X interface of the media converter. If the 1000BASE-X transmitter is off as a result of this fault it can be turned on periodically to allow the condition to clear should the partner device on the 1000BASE-X be using a similar technique. This eliminates the possibility of lockouts that occur with some media converters.
