10BASE-FB Module Descriptions
The ONline Ethernet Port-Switching 10BASE-FB Module is a 2- or 4-port, Ethernet fiber module designed for 3Com ONline System Concentrators. The ONline Ethernet 10BASE-FB Module is a 4-port, Ethernet fiber module also designed for 3Com ONline System Concentrators.
The ONline Ethernet Port-Switching 10BASE-FB Module (Model Number 5104M-FBP) is functionally identical to the ONline Ethernet 10BASE-FB Module (Model Number 5104M-FB1) except for the Port-Switching Module's ability to set each port to an independent backplane network in the concentrator.
The 5104M-FB1 is module-switching only. You can update the 10BASE-FB Module to a port-switching module by installing the ONline Ethernet 10BASE-FB Upgrade Kit.
The 10BASE-FB Modules provide:
❑Fiber backbone connectivity for Ethernet local area networks
❑Direct fiber to-the-desk connectivity
You can directly connect the 10BASE-FB Modules to any other ONline fiber module as well as all of the products in the 3Com 10BASE-FB family, including the:
❑3Com 10BASE-FB Star Coupler
❑3Com 10BASE-FB Fiber Transceiver
❑3Com Fault-Tolerant 10BASE-FB Transceiver The 10BASE-FB Modules:
❑Provide up to 4.0 kilometers distance between any two concentrators
❑Support network diameters up to 4.2 kilometers
❑Contain built-in link redundancy for fault tolerance
