Overview
The AT-FS238a/x and AT-FS238b/x Series Bridging Converters are the
10/100Mbps fast switch single-mode fiber transceivers which can send and
receive on two different wavelengths (1310nm and 1550nm) on a single-mode
fiber cable.
The AT-FS238a/x and AT-FS238b/x Series Bridging Converters include the
following models:
Below is how to differentiate between the models mentioned above:
❑
AT-FS238a/1 = (1310TX/1550RX) - 15 km range
❑
AT-FS238b/1 = (1550TX/1310RX) - 15 km range
❑
AT-FS238a/2 = (1310TX/1550RX) - 40 km range
❑
AT-FS238b/2 = (1550TX/1310RX) - 40 km range
The AT-FS238a/x and AT-FS238b/x Series Bridging Converters are designed
to extend the distance of your network by converting Fast Ethernet data
between twisted pair cabling and single-mode fiber optic cabling. These dual-
port bridging converters can also be used to improve the performance of your
network by dividing it into smaller, more manageable segments.
Each bridging converter features a 100Base-FX fiber optic port and a 10Base-
T/100Base-TX twisted pair port.The fiber optic port has a simplex SC
(Subscriber Connector) connector and an operating distance of 15 kilometers
(9.4 miles) or 40 kilometers (24.8 miles), depending on the model. The twisted
pair port has an RJ-45 connector with a maximum operating distance of 100
meters (328 feet).
