Fiber-optic cables
The lightwave switch use one of three types of fiber-optic cables. To deter-
mine which fiber-optic cable type your lightwave switch uses, refer to the rear-
panel serial number label. This label indicates the installed options which are
defined in the following list:
Option 109:. . . . . . . . . . . . . . . . . . . 12801650 nm, 9/125
µ
m single-mode fiber
Option 163:. . . . . . . . . . . . . . . . . . . 7501350 nm, 62.5/125

m multimode fiber
Switching is bi-directional
The lightwave switches are based on a moving fiber technology where an input
fiber is aligned with any one of N fixed output fibers. The input fiber is posi-
tioned by means of a precision stepper motor. Lightwave switches with two
input fibers allow the user to position either input A1 or A2 to a specific out-
put channel. The non-selected input
may
or
may not
align with another out-
put channel.
Lightwave switches with three or more B channels have an additional posi-
tion called channel O or OFF.
Special ordered instruments
Normal lightwave switches have only one layer installed. (A switch layer is a
switch matrix of A ports and B ports.) However, special ordered instru-
ments may have multiple switch layers installed. If the rear panel shows more
than one set of A ports and B ports, the instrument has multiple switch
layers. Other switch configurations, such as non-blocking matrices are avail-
able as special orders.
Serial numbers
Agilent Technologies makes frequent improvements to its products to
enhance their performance, usability, or reliability, and to control costs. Agi-
lent Technologies service personnel have access to complete records of design
changes to each type of equipment, based on the equipments serial number.
