General Information
The HP 86060C-series lightwave switches cover a broad range of switching
capacity and provide for accurate and repeatable measurements. Configuring
the switch is easy because the signal routing is shown graphically on the dis-
play. You can easily integrate the switch into an automated test system using
SCPI-compatible commands via HP-IB or RS-232 interfaces. The HP 86060C-
series lightwave switches are temperature stabilized.
• The HP 86060C is a compact switch with 4 to 8 output channels and 1 or 2 in-
puts.
• The HP 86061C is a mid-size switch in a half-width chassis, with 1 or 2 input
channels. It can accommodate from 4 to 12 output channels on the front panel,
and up to 18 outputs on the rear panel.
• The HP 86062C is a full-width switch with 20 to 100 output channels.
WARNING On Option 002 dual input instruments, any light on an
unselected “A” channel will likely be output on one of the
unselected “B” channels.
On Option 002 dual input instruments, any light on an
unselected “B” channel will likely be output on an unselected
“A” channel.

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:. . . . . . . . . . . . . . . . . . . 1280–1650 nm, 9/125 µm single-mode fiber
Option 163:. . . . . . . . . . . . . . . . . . . 750–1350 nm, 62.5/125 µm multimode fiber
Option H51: . . . . . . . . . . . . . . . . . . . .750–1350 nm, 50/125 µm 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
Hewlett-Packard makes frequent improvements to its products to enhance
their performance, usability, or reliability, and to control costs. HP service per-
sonnel have access to complete records of design changes to each type of
equipment, based on the equipment’s serial number. Whenever you contact

Care of Fiber-Optic Connectors
Care of Fiber-Optic Connectors
Advances in measurement capabilities make connectors and connection tech-
niques more important than ever. Damage to the connectors on calibration
and verification devices, test ports, cables, and other devices can degrade
measurement accuracy and damage instruments. Replacing a damaged con-
nector can be very expensive, not to mention the lost time. This expense can
be avoided by observing the simple precautions presented in this section.
CAUTION The connectors on the switch are not easily cleaned. Before connecting cables
to the the lightwave switch it is very important they are cleaned following the
procedures in “Cleaning optical connectors” on page 1-17.
Inspecting connectors
Because fiber-optic connectors are susceptible to damage that is not immedi-
ately obvious to the naked eye, bad measurements can be made without the
user even being aware of a connector problem. Although microscopic exami-
nation and return loss measurements are the best way to ensure good connec-
tions, they are not always practical. An awareness of potential problems, along
with good cleaning practices, can ensure that optimum connector perfor-
mance is maintained. With glass-to-glass interfaces, it is clear that any degra-
dation of a ferrule or fiber endface, any stray particles, or finger oil on the
endface, can have a significant effect on connector performance. Many times
an instrument must be serviced to replace a damaged connector when thou-
sands of dollars and lost time could have been avoided if better care were
given to the fiber-optic connector.
Figure 1-1 is a close-up micrograph of a clean cable endface. In contrast, Fig-
ure 1-2 shows a connector endface that was either not cleaned, or not prop-
erly cleaned. Material is smeared and ground into the endface causing light
scattering and poor reflection. Not only is the precision polish lost, but this
action can grind off the glass face and destroy the connector.

1-14
General Information
Care of Fiber-Optic Connectors
Repeated connections made without removing loose particles, or using
improper cleaning tools can lead to physical damage of the glass fiber endface,
as shown in Figure 1-2. When severe, the damage on one connector end can
be transferred to another good connector that comes in contact with it.
