1 - 4 ONline Ethernet 10BASE-FB Module Installation and Operation Guide
10BASE-FB Compliance
The ONline Ethernet Port-Switching 10BASE-FB Modules and the ONline
Ethernet 10BASE-FB Module are fully compliant with the IEEE 10BASE-FB
fiber standard. The IEEE ratification of the 10BASE-FB standard validates
synchronous fiber Ethernet as the choice for backbone links. Synchronous
technology provides robust transmission for fiber Ethernet backbones.
Compliance with the 10BASE-FB standard allows 3Com fiber modules to be
compatible with:
❑ Industry 10BASE-FB-compliant products
❑ Existing 3Com 10BASE-FB technology
3Com 10BASE-FB Modules implement Ethernet/IEEE 802.3 physical layer
functionality on a fiber optic medium. Full interconnection of all devices
that comply with Ethernet V2.0 or IEEE 802.3 specifications are provided,
including:
❑ Minicomputers
❑ Engineering workstations
❑ PC networking servers
❑ Bridges
Theory of Operation
The 10BASE-FB Modules serve mainly as network backbone links. Network
backbone links connect concentrators together. You may also use the
10BASE-FB Modules to connect directly to devices using the:
❑ 3Com 5101T-FB Transceiver
❑ 3Com 5102T-FBFT Fault-Tolerant Transceiver
