Optical Switch 1
1 Introducing the Optical Switch
Main Features
The Optical Switch provides fiber-to-fiber positioning of optical signals for a
number of optical applications. This module, which exists in various
models depending on the number of optical ports and configuration
options it has, allows you to quickly switch light from one fiber to another.
Note: Actual ports may differ from the illustrations.
The Optical Switch enhances test performances by:
minimizing downtime
automating the testing process
reducing manual intervention in ribbon or multifiber testing
enabling remote testing on multiple fibers

Available Models
Note: On all RTUe-9110 models shown above, you can use the upgrade ports to
cascade external switches, or use them as standard switch ports. The
upgrade ports have lower insertion loss (IL) than the other ports, which
makes them particularly well suited for switch cascading.
Note: On all RTUe-9110 models shown above, you can use the common port(s)
as a connection point with the primary switch when the switch is cascaded,
or to receive signal from a test module.

RTUe-9110/RTUe-9120 LED Indicator Description
RTUe-9110/RTUe-9120 LED Indicator
Description
There is one LED indicator on the front panel of the RTUe-9110/RTUe-9120
switch showing its status.
The table below presents the possible statuses once the initial startup
sequence is complete.
LED Status Meaning
a
a. If more than one error is detected at the same time, the color of the LED will be set according to the most
severe error (red as the most severe, followed by yellow).
Green The switch is working properly and is ready.
Green, blinking The initialization of the switch is underway.
Yellow Non-critical hardware error detected.
The temperature of the room where the switch is
located could be slightly too low or too high, or
there could be a hardware malfunction.
Ensure that the temperature falls within the
specified operating temperature range of the RTU-2
unit.
If the problem persists, contact EXFO.
Red Critical hardware error detected.
The temperature of the room where the switch is
located is critically too low or too high, or there
could be a hardware malfunction.
Ensure that the temperature falls within the
specified operating temperature range of the RTU-2
unit.
If the problem persists, contact EXFO.
Off Switch is off or not connected to an RTU-2 unit.

Basic Switching Principles
Basic Switching Principles
The switch ports of 1 x N optical switches are numbered on the front panel,
while the common port is identified with a "C."
These switches are bidirectional. This means that the optical signal can
either enter through the common port and be directed toward any switch
port, or enter through any switch port and then be directed toward the
common port.
1 x N Optical Switch Principle

Introducing the Optical Switch
Optical Switch 13
Basic Switching Principles
Duplex switches follow the same principles as 1 x N switches, but each
port have two fibers.
The FTBx-9150 (2 2 model) is also a bidirectional switch. The two
positions for this switch are known as inserted state and bypass state.

Basic Switching Principles
The FTBx-9150 (2 4 model) is also a bidirectional switch. As illustrated in
the following figure, it can be set to six positions. In three of these
positions, one or both input channels do not transmit light to output ports.
