Switching Optical Routes How to Use an Optical Switch module
208 Agilent 8163A/B, 8164A/B, and 8166A/B User’s Guide, Fourth Edition
Dependent and Independent Routing
Dependent Routing If Route A <-> is dependent on Route B <->, editing the number of the
port assigned to Route A <-> automatically updates the number of the
port assigned to Route B <->.
For example, an Agilent 81594A/S 2x2 non-blocking (crossover) switch
has two routes described by [Route A <-> 1] [Route B <-> 2] and
[Route A <-> 2] [Route B <-> 1].
Independent Routing If Route A <-> is independent of Route B <->, there are two separate
switched channels. There are two numbered ports that you can assign
to Route A, and two separate numbered ports that you can assign to
Route B.
For example, an Agilent 81592A/S dual 1x2 switch allows you to
switch Route A <-> to [Route A <-> 1] or [Route A <-> 2], and
Route B <-> to [Route B <-> 1] or [Route B <-> 2].
How to set Route A
To switch the route between port A and another numbered port:
1 Use the Cursor key to highlight [Route A <->], then press Enter.
2 Use the Cursor key to enter the number of the port required.
If the Switch module incorporates independent routing, you cannot
select a numbered port assigned to port B.
3 Press [OK].
If the switch module has dependent routing, [Route B <->] is
updated automatically.
The [Edit] softkey is functionally equivalent to the Enter hardkey.
The [Menu] softkey allows you to assign a route for port A and port B
in turn.
