Description: Allied Telesis AT FS238B/1 - Fiber media converter - 100Mb LAN - 10Base-T, 100Base-FX, 100Base-TX - RJ-45 / SC single-mode - up to 15 km - 1550 (TX) / 1310 (RX) nm
Mfr Part #: AT-FS238B/1-60
The AT-FS238 media converter is a 10/100Mbps copper to single-mode fiber media converter which can send and receive on single strand fiber. These units are designed to be used in pairs in a network topology to provide point-to-point access. The AT-FS238 converts 10/100TX (RJ-45) to 100FX (SC) and will transmit up to 40km on high quality fiber optic cable. Both ports feature full and half-duplex operation. The AT-FS238 is easy to install and does not require software configuration or management. Additionally, it can be used almost anywhere due to its small physical size, choice of external power supplies and options to be rack mounted.
- LEDs for unit and port status
- Auto MDI/MDI-X
- DIP switches for port configuration
- Supports half and full-duplex operation
- Data packet forwarding and filtering at full wire speed
- Store and forward switching mode
- Automatic address learning and aging
- IEEE 802.3u compliant auto-negotiation
- Auto MDI/MDI-X
The AT-FS238 media converter features automatic MDI/MDI-X. The 10/100TX (RJ-45) port automatically determines the configuration of the port on the device to which it is connected and then configures itself appropriately. This feature allows you to use either crossover cables or straight-through cable when connecting a device to the copper port.
- MissingLink and Smart MissingLink (SML)
The MissingLink 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 one of the ports, such as the loss of connection to a node, it shuts down the connection to the other port, thus notifying the node that the connection has been lost. The AT-FS238 also features Smart MissingLink (SML). This feature monitors network connections and provides notification if a network segment fails. This allows network managers to quickly identify the source and location of a failed segment and minimize downtime.
