The FIBI-1000 is a standalone optical fiber media converter for 1000Base Ethernet to fiber that also provides NMS functions for Link-Loss-Forwarding, Remote-Monitoring-Status, and Loop-Back-Test. When auto-negotiation is selected, these units will autonatically tailor themselves to convert both half-duplex and full-duplex signals, depending on your specific networks needs. Features Complies with IEEE 802.3ab, 1000Base-TX, IEEE 802.3z, 1000Base-SXLX Gigabit Ethernet Standards.Provides one 1000Base-TX port, one 1000Base-SXLX port, voltage 3.3V SX-Multi-mode, LX- Single-modeThree versions supports fixed SC or LC connector types, GBIC socket with SC, or SFP with LC.Sockets allow easy replacement of the snap-out transceiver models.Supports Full-duplex and Half-duplex mode for the Fiber and LAN ports.Automatic MDIMDX crossover function.6 diagnostic LEDs for Power, TX linktransmit, FX linktransmit, FullHalf Duplex mode, CPE, LLF and LBT.Advanced Features:1) Supports Link-Loss-Forwarding function via front panel DIP switch. 2) Supports for the Loop-Back test via front panel DIP switch. 3) Supports remote monitor status via front panel DIP switch.
