(Attenuation = Cable loss + LED aging loss + Insertion loss + safety factor) 3.3.
Magnum14E Media Converters Installation and User Guide (10/02) The Magnum 14E, with full-duplex operation as a standard feature, can be used in these applications. When installing the Magnum 14E in a full-duplex segment, it is important to consider the combined overall segment length of both of the attached media types. The overall segment length is calculated by adding together the segment lengths on both sides of the Magnum 14E Media Converters.
Magnum14E Media Converters Installation and User Guide (10/02) Media Distance Formula for Magnum 14E, full-duplex: X% + Y% < 100% Where X = Where Y = The segment distance on one side of the Magnum 14E Media Converter divided by the Standard Maximum Media Distance for that media type, x 100% The segment length on the other side of the Magnum 14E Media Converter divided by the Standard Maximum Media Distance for that media cabling type, x 100% www .

Magnum14E Media Converters Installation and User Guide (10/02) Note 1: Where more than one media converter is used in one segment run, the percentages for all of the cabling lengths in the run must be added together and must not exceed 100%. In another instance, a Magnum Media Converter is used to connect a single mode fiber (100BASE-FX) with a twisted pair (100BASE-T) segment. In this example, the length of fiber Segment X is 8500m (27,880 ft).
Magnum14E Media Converters 3.4.3 Installation and User Guide (10/02) Segment Distances, Half-duplex mode Fast Ethernet shared bandwidth devices operate with multiple nodes in a traffic domain. When a node attempts to send a packet, it may hit another packet passing by, i.e., a collision may occur. This is normal and does not cause a problem because the Ethernet protocol provides for this situation and requires that the sender wait and try again.
Magnum14E Media Converters Installation and User Guide (10/02) (PDV or Path Delay Value) in diameter between any two nodes. Nodes in a collision domain are connected by means of a repeater or repeaters such that no bridging or switching devices are present between any two nodes in the cluster.

PDV = (sum of cabling delays) + (sum of repeater & media converter delays) + (DTE pair delays) + (safety margin) PDV is the Path Delay Value of the worst case path. For the network to adhere to IEEE 802.3u standard, this value must be less than 512 BT. The safety margin is specified in BT and may be a value between 0 and 5.
Magnum14E Media Converters Installation and User Guide (10/02) media has a PDV of about 1 BT per meter of length. The Magnum 14E has a PDV of 20 BT. Therefore, in shared Fast Ethernet applications, the 14E uses about 80 meters of equivalent cable distance to convert from TX media to fiber FX media, i.e., it consumes almost as much of the available PDV as a Class II repeater.
Magnum14E Media Converters Installation and User Guide (10/02) The solution is : 512 = total available Bit Times in a collision domain diameter, minus 100 BT for two DTEs on each end leaves 412 BTs, minus 180 BT for two Class II repeaters leaves 232 BTs, minus 20 BT for two 10-meter TP cables for hubs to users leaves 212 BTs, minus 10 BT for two short TP cables from the hubs to 14E’s leaves 202 BTs, minus 40 BT for two Magnum 14Es leaves 162 BTs for fiber cable, which indicates a fiber cable length of abo
Magnum14E Media Converters Installation and User Guide (10/02) allowable maximum cable distance vs. TP cable without the 14Es. Consider a more typical use of Magnum 14Es in a shared Fast Ethernet segment. A stack of Fast Ethernet hubs comprises the only repeater in the collision domain, and the users and servers in the local workgroup are each connected via Category 5 twisted pair cable, a maximum of 30 meters (100 ft.) in length.
Magnum14E Media Converters Installation and User Guide (10/02) 3.5 Connecting Fast Ethernet Media Connecting Ethernet media to the Magnum 14E Media Converter is very simple and straightforward. Using a properly terminated media segment, simply attach the cable end to the appropriate connector. See Sections 4.2 and 4.3 for a description of the LEDs. 3.5.

For all 14Es,the Link-Pass-through feature is standard, the two LINK LEDs operate together, and either both LEDs are lit or neither is lit. Both of the attached cables must be operable for LINK to be indicated. Absence of LINK does not point to the problem cable segment, and the fault may be in either. 3.5.
Magnum14E Media Converters Installation and User Guide (10/02) 3. Connect the Transmit (TX) port (light colored post) on the Magnum 14E to the Receive (RX) port of the remote device. Begin with the color-coded strand of the cable for this first “Transmit-to-Receive” connection. 4. Connect the Receive (RX) port (dark colored post) on the 14E to the Transmit (TX) port of the remote device. Use the non-color coded fiber strand for this. 5.
Magnum14E Media Converters Installation and User Guide (10/02) 1. Before connecting the fiber optic cable, remove the protective dust cap from the tip of the connector on the Magnum 14E. 2. Wipe clean the ends of the connector with a soft cloth or lint-free lens tissue dampened in alcohol. Make certain the connector is clean before connecting.
