The LAN3200A Gigabit Ethernet full-duplex module provides two 1000Base-SX ports with a physical interface of 850 nanometer multi-mode fiber. The LAN-3200A follows the IEEE 802.3z specification and is used to test the performance conformance and interoperability of Gigabit Ethernet backbones. Upstream traffic and throughput testing can be performed by using a LAN-3200A module in combination with a LAN-3100A module.
