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. For network applications that require routing, you can attach this
switch to a router or WAN gateway.
3. As a general rule the length of fiber optic cable for a single switched
link should not exceed:
• 10GBASE-SR: 300 m (984.25 ft) for multimode fiber.
• 10GBASE-LR: 10 km (6.21 miles) for single-mode fiber.
• 10GBASE-ER: 40 km (24.85 miles) for single-mode fiber.
However, power budget constraints must also be considered when
calculating the maximum fiber optic cable length for your specific
environment.
