| Need cost-effective, reliable hubs for your network? The virtue of our hubs is to extend a 10BASE-T system beyond two nodes or to increase network distances beyond the 100-meter segment limit of the 10BASE-T specification. To maximize distance, the typical network uses twisted-pair wiring for the end devices and fiber cables for the inter-hub links. Each twisted pair can be as long as 100 m and the total length of inter-hub fiber can be as much as 2000 m. The network diameter cannot exceed 2400 m. In a shared Ethernet environment the length of each fiber segment depends upon the number of hubs used.
Two EI Series models provide expansion through twisted-pair cabling — the four-port EI4-10T and the popular 8-port EI8-10T. The line is enhanced with its fiber optic versions — the 5-port EI5-10T/F and the six-port EI6-10T/F. The EI6-10T/F has 4 ports for twisted-pair that support the signaling standards of 10BASE-T and the two fiber ports support the 10BASE-FL interface using ST connectors. The EI5-10T/F has one less fiber port.
Fiber optic segments make it ideal for building control and industrial control applications where distance and robustness are important. Fiber optic links also provide a layer of isolation and increased immunity to electrical noise and other external influences usually encountered in an industrial environment.
