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 throughout 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. The multimode fiber modules are fitted with SC connectors, but you
can attach an ST plug to the switch using SMC's optional SC-to-ST
plug converter (Part Number: 99-012034-091, for 62.5/125 micron
cable only). If you do use an ST plug converter, be sure you run cable
from the Rx (Tx) port on the module to the Tx (Rx) port on the target
device.
5. As a general rule, the length of fiber optic cable for a single switched
link should not exceed:
•
•
However, power budget constraints must also be considered when
calculating the maximum cable length for your specific environment.
1000BASE-SX/LX — 550 m (1805 ft) for multimode fiber or
5 km (16404 ft) for single-mode fiber.
100BASE-FX — 2 km (1.24 miles) for multimode fiber or 20 km
(2.43 miles) for single-mode fiber.
