❑3Com Fault-Tolerant 10BASE-FB Transceiver - The 3Com Fault-Tolerant10BASE-FB Transceiver (Model Number 5102T-FBFT) provides fault tolerance to-the-desktop. The transceiver connects an existing network to a fault-tolerant fiber backbone network. It also provides a fault-tolerant network connection for a mission-critical device.
❑3Com 10BASE-FB Star Coupler - The 3Com 10BASE-FB Star Coupler (Model Number 9308S-FB) is a pure fiber hub that provides both backbone and to-the-desk connectivity.
10BASE-FB Cable and Connector Specifications
This section contains information on 10BASE-FB cables, and connectors. Use the information in the following sections to ensure that the cables and connecting hardware meet requirements.
You can use many types of fiber cables and connectors to link your 10BASE-FB Module to your network. These cables and connectors are explained in the sections that follow. For proper operation, use only approved cables when you install all equipment.
10BASE-FB Cables
The fiber optic cable diameters that the 10BASE-FB Module supports must meet the following qualifications:
❑50/125, 62.5/125, 85/125, or 100/140 μm graded index fiber
❑duplex fiber with a 150 MHzKm rating or better
Note that network link distances are affected by the grade of cable you choose. The quality of fiber cable varies significantly. Typically, measure quality in terms of the signal loss per km. The less amount of loss, the better the cable quality. Good quality 62.5 μm fiber typically has a 3 to 4 dB loss per kilometer.
