Application Notes - AMX NXA-ENET8-2POE Instruction Manual

Application Notes

1. Full-duplex operation only applies to point-to-point access (such as when a NXA-ENET8-2POE is attached to a workstation,
server, or another switch). When the NXA-ENET8-2POE 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: 10 km (6.2 miles) for single-mode fiber.

1000BASE-LH: 80 km (50 miles) for single-mode fiber.

100BASE-FX: 20 km (12 miles) for single-mode fiber.

However, power budget constraints must also be considered when calculating the maximum cable length for your specific
environment.
