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. Avoid using flow control on a port connected to a hub unless it is
actually required to solve a problem. Otherwise back pressure jamming
signals may degrade overall performance for the segment attached to the
hub.
3. As a general rule the length of fiber optic cable for a single switched link
should not exceed:
•
1000BASE-SX: 550 m (1805 ft) for multimode fiber.
•
1000BASE-LX: 5 km (3.1 miles) for single-mode fiber.
•
1000BASE-ZX: 100 km (62.14 miles) for single-mode fiber.
However, power budget constraints must also be considered when
calculating the maximum cable length for your specific environment.
