10BASE-FL Cable and Connector Specifications
This section contains information on 10BASE-FL and fiber products, cables,
and connectors. Use the information in the following sections to ensure
that the cables and connecting hardware meet requirements.
In addition to the ONline Ethernet 10BASE-FL Module, 3Com offers the
ONline 10BASE-FL Transceiver (Model Number 5101T-FL1-ST,
5101T-FL1-SMA, or 5101T-FL1-FC). The 10BASE-FL Transceiver connects
the ONline 10BASE-FL Module to the fiber or 10BASE-FL network.
Fiber Cables and Connectors
You can use several types of fiber cables and connectors to link your
10BASE-FL 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.
Fiber Cables
The fiber optic cable diameters that the 10BASE-FL 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 kilometer. The less amount of loss the
cable has, the better the cable quality is. Good quality 62.5 µm fiber
typically has a 3 to 4 dB loss per kilometer.
