Note
Exception in the naming of X320-3LD FE
With the X320-3LD FE IE switch, the key to the name is different. The position -3LD covers a
total of 3 connectors (1-2) of which only 2 connectors are LD, refer to the explanation below:
● Port 21: Multimode
● Port 22: LD (long distance, single mode)
● Port 23: LD (long distance, single mode)
Note
2 optical interface transceivers possible (X320-3LD FE)
The device is also equipped with 2 optical interface transceivers.
●
1)
Fast Ethernet, long distance interface
●
2)
Fast Ethernet, multimode interface
As a result, the electrical data in the technical specifications is divided into two parts:
transmitter output optical and receiver input.
