  • Page 46: Fiber Optic Sfp Devices

    | Making Network Connections HAPTER Fiber Optic SFP Devices Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length. Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise back pressure jamming signals may degrade overall performance for the segment attached to the hub.

  • Page 47: Figure 16: Making Connections To Sfp Transceivers

    | Making Network Connections HAPTER Fiber Optic SFP Devices Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port.
