Fiber Specifications
The following table presents the fiber specifications. The SCE 2000 may be ordered with either
Multimode or Single Mode transceivers. The transceiver type is indicated on the front panel under the
ports. Note that both transceivers on any individual SCE 2000 are the same, either 850nm Multimode
OR 1310nm Single Mode.
Step 1
Take the appropriate fiber optic cable (see
Fiber Specifications, page 6-8
) and plug it into the
appropriate GBE port on the front panel of the SCE 2000.
Make sure to push on the connector until you hear a click, which indicates that the connector is fully
inserted and secured in the receptacle. Always make sure that you insert the connector completely into
the socket.
