  • Page 16: Product Description

    A variety of twisted-pair-to- fiber models provide for multi-mode or single-mode, transparent full- and half-duplex mode, and normal or Link Pass-through operation. Magnum TF14 and TB14 Media Converters cost significantly less than full repeaters and can be used whenever media distance limitations will not be exceeded in the segment.
  • Page 17 In addition, the TF14 allows fiber segments to be used with new RJ-45 Ethernet hubs and switches that have insufficient (or none at all) fiber ports.
  • Page 18 Fiber models: The Magnum TF14 (multi-mode ST), TF14s (single-mode ST), and TF14-LP (Link Pass-through, ST) are equipped with one fiber-ST and one twisted pair RJ-45 connector for use in IEEE FOIRL or 10BASE-FL compliant networks. The up-link (10BASE-T)

    When a twisted-pair to fiber media converter is introduced, the standard models of these products (such as the Magnum TF14) treat each attached cable segment as a separate entity. The LEDs on the media converter separately indicate LINK on each port,...
  • Page 26 The Link-Pass-through model, TF14-LP, provides the LINK “see-through” feature desired for managed networks. On these models, either both LINK LEDs are lit or neither is lit. And, the TF14-LP operates in transparent half- and full-duplex mode. The following diagram illustrates the standard condition, no Link Pass-through.
