ipolex's A7S2 series Media Converter is use to expanding existing Gigabit Ethernet networks. The easy implementation and expansion of 1000Base-TX/FX networks can be further assured with this converter. The converter is completely transparent when connected so the network performs exactly the way it did before - only now, it allows the co-existence of both copper and fiber mediums. Main Features: Complies with IEEE 802.3, IEEE 802.3u, IEEE802.3z, IEEE802.3ab, IEEE 802.3x Auto negotiation function allows UTP port to auto select 10M, 100M or 1000M Ethernet port supports MDI/MDI-X auto crossover Extends distances up to 80KM (singlemode fiber) Auto MDI/MDI-X support on RJ-45 port Support Full Duplex and Half Duplex Status LED's for TX,FX LINK/ACT, POWER,FDX to easily monitor network status 1Mbit RAM for data buffer Supports jumbo frame size 9K bytes Optical Port: 1550nm singlemode Connectors: LC connector TX Power (dBm): 0~4 Rx Sens.
