Allied Telesis AT FS232

Allied Telesis AT FS232 ... 100Mbps Fast Ethernet network. The AT-FS232 is designed to extend the distance of your network by converting Fast Ethernet data between twisted pair cabling and single-mode fiber-optic cabling. The AT-FS232 features a 100FX fiber-port and a 10/100TX twisted- pair port. The fiber-optic port features an SC connector and an operating distance of 2 kilometers (6, 561 feet) to 90 kilometers (55.8 miles) depending on the model. The twisted-pair port has an RJ-45 connector with a maximum operating distance of 100 meters (328 feet).

Many new backbone switch products now support the industry standard IEEE 802.1Q specification for Virtual LANs (VLANs) that send extra-long data packets on the network. The AT-FS232 switches are fully compatible with these long packets, enabling them to be used in modern networks. Switches not supporting this feature will discard these extra long packets, making them unsuitable for modern networks.

The small size and external power supply of the AT-FS232 allow them to be used almost anywhere. Additionally, they can be mounted in a chassis along with Allied Telesis' media converters, allowing users to construct any mix of network conversions when they add the optional redundant power supply.

The Missing Link feature allows the ports on the media converter to pass the Link status of their connections to each other. When the media converter detects a problem with a port - such as the loss of connection to a node - it shuts down the connection to the other port, thereby notifying the node that the connection has been lost. The ATFS232 also features Smart Missing Link (SML) - a feature that monitors network connections and provides notification when network segments fail, allowing network managers to quickly identify the source and location of failed segments and minimize downtime.
