full- and half-duplex operation and can handle numerous fiber types.
These converters auto-adapt to the highest performance level
supportedbythedevicethatisconnectedtotheUTPport.Whenthe
device supports full-duplex, the converter adapts to full-duplex mode
andcreatesa200-Mbpsbandwidth.Whentheconnecteddevice
supports only half-duplex, the converter adapts to this mode and
createsa100-Mbpsbandwidth.Full-andhalf-duplexoperation
can also be controlled by a manual override switch.

Theconvertersauto-adapttothefull-/half-duplexandflow-control
servicessupportedbythedeviceconnectedtoitsUTPport.User-
selectable override options set the desired mode.
The converters operate in full-duplex to provide an effective
2-Gbpsdatarateorinhalf-duplexmodetoprovidea1-Gbpsrate.
This maximizes the throughput when connecting to high-bandwidth
full-duplex services such as servers or switches.
Network flow control is supported via an auto-selected or user-
selected “Pause” function that helps relieve network congestion
by providing “backpressure” to the sending device.
Theconvertersupports850-nm(SX),1300-nm(LX),or1550-nm
fiberandusesSC,MT-RJ,orLCconnectors.TheMultimodeSX

or other network-managed devices that monitor link availability.
A user-selectable override is provided to isolate the link detection
to a per-segment basis.
Theconverter’sUTPportusesamodularEIA/TIA568RJ-45
connector and supports Category 5 or higher wiring with distances
ofupto328feet(100m).Automaticpolaritydetectionandcorrection
assists in network installation and maintenance.
Token Ring UTP/Fiber
ForTokenRingLANswithfiber-to-copperconversions,these
models automatically sense and configure themselves to the network
ring speed. They also self-configure to attached devices through an
automatic sensing circuit.
TheUTPportcanattachtoaworkstation’snetworkinterfacecard,
ring-in/ring-outport,orlobe.Thisconvertercanalsosupportserver
or workstation fiber attachments and fiber ring extensions.

and12.4miles(20km)usingsingle-modefiber.
These models also test cable integrity in the network.
