Application Notes
1. Full-duplex operation only applies to point-to-point access (such as
when a switch is attached to a workstation, server or another switch).
When the switch is connected to a hub, both devices must operate in
half-duplex mode.
2. When a switch is connected to a hub or any kind of shared media,
remember to turn off back pressure to prevent jamming packets from
being propagated thoughout the hub.
3. For network applications that require routing between dissimilar
network types, you can attach the TigerSwitch 10/100 units directly to
a router.
4. As a general rule the length of fiber optic cable for a single switched
link should not exceed:
• Gigabit Ethernet — 550 m (1805 ft) for multimode fiber or 5 km
(16404 ft) for single-mode fiber.
• Fast Ethernet — 2 km (1.24 miles) for multimode fiber or 20 km
(2.43 miles) for single-mode fiber.
However, power budget constraints must also be considered when
calculating the maximum cable length for your specific environment.
