for Test Automation
• Temperature stabilized performance with low insertion loss
• Easy-to-use manual interface with visual signal path display
• Repeatable switching with 10 million cycle minimum life
• SCPI-compatible remote commands via GPIB and RS-232
• Multilayer switches and other custom configurations available
The Agilent 86060 switch family
features an easy-to-use manual interface and a visual signal
routing display. The interface
allows quick manual operation
for initially setting up a measurement or for quick investigation
of test device performance.
Selected switch positions can
be saved and recalled. The
switches can be easily integrated into automated test
systems using SCPI-compatible commands via GPIB or
RS-232 interfaces.
Agilent 86060C
Features and Benefits
Agilent’s new “C” series of lightwave switches are now temperature stabilized and thus, offer
excellent repeatability and
insertion loss stability. They
are designed for long reliable
service with low insertion loss
and low back reflections, for
accurate lightwave measurements in automated test setups
where the switch is an integral part of the measurement.

The Agilent 86060 series of programmable lightwave switches
cover a broad range of switching capacity and provide easy
signal routing for accurate
and repeatable measurement
automation. These switches
provide an important building
block for implementing automated test systems in manufacturing. They are designed
to be versatile and can be
easily configured with several
different options for automated
test environments.

The Agilent 86060C is a compact
switch available with four to
eight output channels and one
or two inputs. The switch is
designed for easy configuration with HP optical attenuators, lightwave multimeters,
OTDRs, and other lightwave
test instrumentation for either
benchtop or automated system
applications.
New to the “C” series switch
family is the Agilent 86061C—a
mid-size switch in a half-width
chassis, available with one or
two input channels. It can
accomodate from four to twelve
output channels on the front
panel and up to eighteen outputs on the rear panel.
The Agilent 86062C is a fullwidth instrument with 20 to
100 output channels. It is
designed for automated production and evaluation testing
of large numbers of devices.
The Agilent 86060 Series Lightwave Switches are designed
for 9/125 µm single-mode, as
well as 62.5/125 and 50/125 µm
multi-mode operation. Switching is bi-directional. The 1xN
switching module is built around
a precision stepper motor.
Standard configurations include
fiber “pigtails” or FC, SC, or ST
connectors. Other connector
types including DIN, Diamond
or angled physical contact are
available on request. (Unlike
most Agilent products, these
connector types are not interchangeable.)
Switching Operation
The basic 1xN switching design
of the 8606XC is shown in
Figure 2. It consists of a single
input channel that is routed
through a movable arm. The
arm is controlled by the stepper motor to align the input to
any output position1. Very low
insertion loss and excellent
repeatability are achieved
using high quality optics and
precise motor control.
A two input switch diagram is
shown in Figure 3. In this configuration, the two input arms
move together to connect
either input channel to an
output channel. The standard
Agilent 8606XC design is called
“non-blocking” since the unselected input channel is not
blocked to the output. In this
example, connecting A1 to B1
may also connect A2 to B2.
“Blocking” type switches that
only allow one of the input
channels to be connected to
the output can also be configured in the Agilent 86060C
family. These are available as
special options at this time.
For additional information about
blocking switches, please refer
to the custom switching configuration section of this document or contact your local
Agilent field office.

They do not imply that transmission can
only occur in one direction. The 86060C
series switches are all bi-directional (i.e.,
signals can transmit in either direction).

Custom configurations
Multi-layered Switches
The 86060C family offers multilayered switch configurations
in a single chassis. This provides added flexibility and
functionality while minimizing
rack or bench space. Integrated
multi-layer software can control up to 4 separate switch
layers in a single box. An
example of a 4 layer switch is
shown in Figure 4. It consists
of two 1x2 switches on layers
S1 and S2 and two 2x8 switches in layers S3 and S4 in a single chassis. The front panel
display in Figure 5 shows the
channel configuration in each
of the four layers.
The first type of blocking
solution is where every other
output channel position is utilized (see Figure 6). In this
configuration only one input
channel can be connected to

Blocking Switches
In addition to the standard
“non-blocking” design, the
Agilent 8606XC series switches
can be specified in a “blocking” configuration (i.e., only
one input channel can be connected to the output). This is
achieved in two ways.

In addition to the many standard options, Agilent offers a

specific test applications.

an output channel, while the
other input is not aligned to
any connecting port. The advantage to this design is that low
insertion loss can be maintained.
However, the total number
4
of available output channels
is reduced by half. For the
Agilent 8606XC family, the limit
would be 50 output channels
in this blocking configuration.
If more than fifty channels are
required, another blocking
solution is available in the “C”
version by adding an Mx1
switching element in front of a
1xN armature switch (See
Figure 7). The implication of
this design is that there is
slightly higher insertion loss
than the standard “C” specification, and the input/output
channels are controlled on
two separate layers via front
panel keys or remote control.
When programming the switch,
two SCPI commands are needed to connect a one of the
input channels to a desired
output channel.

The 8606XC family of switches can be configured to have
more than 2 input channels.
Up to 4 input channels can be
accomodated. Figure 8 depicts
a 4xN configuration. In this
design, the four input arms
move together to connect any
input channel to any output
channel.

configurations (such as angled
connector contacts, enhanced
specifications, special fiber

connected for the test (for
example, isolators, patchcords,
or attenuators). Insertion loss
is measured versus temperature.
Reference channels are used
for system calibration and to
compensate for system drift. This
system could be expanded to test
return loss versus temperature
with the addition of a coupler
and a reflectance standard.
This test system can also be
set up using a single Agilent
86062C switch with two layers.

A well-implemented automated test system can help reduce
manufacturing costs. A wide
range of measurements can be
performed and recorded much
more rapidly, eliminating the
need to manually reset operating conditions. Automated
systems can be implemented
to reduce the necessary operator skill level and amount of
training required. They can
also reduce the time spent
recording, recovering, and
publishing test results.
Increasing measurement
throughput by greatly reducing
time per test, a single automated test system can do the
work of several manual stations,
thereby reducing both cost
per test and the total capital
investment required for the
test.
Qualification testing can be
very expensive, with the additional cost of operating an
environmental chamber on
top of tying up lots of test
equipment for long periods to
test multiple devices. Figure 9
shows an automated environmental test system using two
Agilent 86060C Lightwave
