death or serious injury.
CAUTION Indicates a hazardous situation which, if not avoided, could result in
minor or moderate injury.
NOTICE Indicates a hazardous situation not related to personal injury.
Safety precautions
Laser safety
The RA3P Raman amplifier emits invisible laser radiation through the line port that can
be potentially harmful to the human eye and skin.
Note: The safety information and classifications described in this section refer only to
pump laser radiation created within the RA3P Raman amplifier itself and exiting the
line port. Any external radiation (in particular the optical transmission signal) entering
the amplifier through any of the ports will exit through the other ports, and with
respect to such radiation the amplifier is considered a passive device.
DANGER
Eye hazard
Looking directly, or through a magnifying instrument (e.g. microscope), into any optical
fiber cable or connector can cause damage to the eye.
Do not look directly, or through a magnifying instrument, into any optical fiber.

During normal operation, when the RA3P Raman amplifier is connected through the line
port to a closed fiber transmission line, the amplifier may emit up to 700 mW of radiation
(limited by hardware). However, as this radiation is enclosed within the transmission line,
it poses no hazard. A potential hazard can occur when a fiber break or connector opening
occurs. To avoid this, the RA3P Raman Amplifier is equipped with four different
firmware mechanisms designed to detect a fiber break or connector opening, and activate
Automatic Power Reduction (APR) of the RA3P Raman pumps to reduce output power to
below the level defined for class 1M laser products
Note:When an optical cable is not attached, place a protective cap over the cable's
connector.
WARNING
Eye hazard
Invisible laser radiation may be emitted from the line port connector, or fiber connected
to this port.
Do not look into the beam or view it directly with optical instruments.
APR protection
DANGER
Eye and skin hazard
Once the product level of APR protection is disabled, the amplifier is classified as a class
4 laser product, and exposure to direct or scattered radiation may cause eye and/or skin
damage.
DANGER
Eye and skin hazard
Once the system level protection of the amplifier is disabled, the system may contain
locations classified as class 4 hazard levels, where exposure to direct or scattered
radiation may cause eye and/or skin damage.
There are two levels of APR protection, the product level and system level. The product
level APR involves only the RA3P Raman amplifier itself, and is based on detection of
the pump back reflection and Amplified Spontaneous Emission (ASE) in the short-band
(1500-1520nm for C-Band amplifiers). The product level protection ensures that opening
the line port connector of the amplifier, or occurrence of any fiber break or connector
opening in jumpers in the vicinity of the amplifier will activate APR. The RA3P Raman
amplifier product is thus classified as a class 1M laser product according to IEC
60825-1:1993+A1:1997+A2:2001, and CDRH 21 CFR 1040.10.

The product level of APR protection is password protected, and may only be disabled
upon pump unit provider authorization.
The second level of APR protection is a system level protection, and refers to operation of
amplifier within a communication system. When system level protection is enabled, it
allows the entire system to be classified as a class 1M system according to IEC
60825-2:1993+A1:1997+A2:2001.
Note: For more information regarding APR mechanisms, refer to chapter Automatic
power reduction (APR) (p. 2-5)
Laser radiation information
When a potential safety hazard is present (when one or both of the APR protection levels
are disabled), the following should be noted:
Maximum output power of laser radiation emitted through the line port is 29dBm
(700 mW).
Emitted wavelengths are in the C or L Bands and pump bands, rendering the spectral
range of 1420nm to 1564nm.
Beam divergence from a broken fiber or open connector is higher than 6.9 / 0.12
radians (Numerical aperture).
Beam Mode Field Diameter at the output of a broken fiber or open connector is below
11 m.
Warnings
1. Only the upper covers of the RA3P may be opened to replace fans. No other panel
should be opened for any purpose.
2. Do not try to repair the RA3P (apart from fan replacement) - Only personnel certified
by pump unit provider are eligible to repair the RA3P
3. It is forbidden for any purpose to open the Raman pump module located within the
RA3P.
4. Opening the Raman pump module within the RA3P may expose you to harmful laser
radiation. An open Raman pump module is classified as a class 4 laser product
5. Do not look directly at or through any optical magnifying instrument (e.g.
microscope) into the optical connectors.
6. When Automatic Power Reduction (APR) mechanisms are disabled, the RA3P is
classified as a class 4 laser product
7. When connecting the RA3P to a fiber line, use only connectors having Mode Field

2 2The RA3P Raman amplifier
RA3P Raman amplifier hardware
Distributed Raman amplification
ARaman amplifier is based on the Raman scattering process. In this process an incident
photon is scattered to a lower energy photon, while initiating a transition of the fiber
molecules between two vibration states. In the Raman amplifier, stimulated Raman
scattering produces a photon with the same wavelength, phase, and polarization as the
original signal and thus the stimulated scattering mechanism amplifies the signal. The
gain medium in the case of the distributed Raman amplifier is the silica transmission fiber
itself. Amplification occurs along a few tens of kilometers adjacent to the pump unit.
Hardware overview
The RA3P Raman amplifier contains an FPGA and micro processor-controlled Raman
pump module for C-Band (1528.4-1564.7nm) distributed Raman amplification. The pump
module includes three pump laser diodes at different wavelengths and/or polarizations. It
features multiple independent laser safety mechanisms based on Automatic Power
Reduction (APR). This allows both the RA3P Raman amplifier itself and the network
within which it is installed to be classified as class 1M laser products according to IEC
60825 parts 1 and 2, and CDRH 21 CFR 1040.10. This provides eye and skin laser
safely for the operating personnel, and also protects optical and electronic gear deployed
along the lines. The same mechanisms are used to alert system management of line
deterioration and reduction in the amplifier distributed gain.
In addition to the pump module the RA3P includes redundant user replaceable cooling
fans, as well as a communication module supporting the Small Network Management
Protocol (SNMP) through a standard Ethernet RJ45 connector.
Pump module block diagram
The following block diagram describes the main building blocks of the pump module
within the RA3P.

In counter propagating operation, the line port (through which the pump energy exits) is
connected to the output of the transmission fiber. The Raman amplified signal enters the
line port and exits through the EDFA port to an EDFA amplifier following the Raman
amplifier.
the following provides a brief description of the various detectors within the pump
module:
Detector Pes - Measures back reflected light in the pump wavelengths entering
through the line port
Detector Short Band DC - Measures ASE power within the "Short" band (1500-1520
nm for C-Band amplifiers) entering through the line port. In counter-propagating
direction the measured power also includes that of the supervisory channel, typically
located within the Short band.
Detector Short Band MOD - This detector is used only in counter-propagating
operation, and measures the modulation power of the OSC.

Detector Pump power - This detector measures the composite pump power exiting the
line port.
Detector Dpin Line - This detector measures the power within the C Band entering the
amplifier from the line Port.
Detector Dpin EDFA - This detector measures the power within the C Band entering
the amplifier from the EDFA Port.
Detector OSC forward - This detector is used in co-propagating operation, and
measures the supervisory channel power entering from the supervisory port.
Pump modes of operation
The RA3P Raman amplifier supports three operation modes:
1. Max pump power mode: In this mode maximum pump power is launched though the
line port into the transmission fiber. The Ratio between different wavelength pumps is
set according to the transmission fiber type.
2. Gain setting mode: In this mode the pump power of each wavelength is adjusted to
provide a required average gain and gain flattening according to the transmission fiber
type.
3. Manual pump power mode: In this mode the pump power for each of the pump laser
diodes can be set manually
Safety and automatic power reduction
OSC
The RA3P Raman amplifier uses the Optical Supervisory Channel (OSC) to provide for
the safety of operating personnel and to protect transmission equipment.
OSC protection ensures that the product is qualified as a class 1M device according to
IEC 60825-2. This mechanism ensures that when the transmission line fails, even tens of
kilometers from the amplifier location, the APR of the RA3P Raman pumps will be
activated.
This protection mechanism is essential for distributed Raman amplifications for the
following reasons:
Pump power launched from the amplifier line port is high, up to 700mW, which is
harmful to the human eye and skin, and can damage optical and electronic equipment.
Because the RA3P Raman amplifier is a distributed amplifier, it is possible that a loss
of input signal will not be detected, and the amplifier will not be shut down, even if a
fiber break has occurred only a few kilometers from the amplifier. This is due to large
Amplified Spontaneous Emission (ASE) generated along the transmission line within
the operating band. In lumped amplifiers this is not a problem, because ASE is only
generated within the amplifier itself.

For a detailed discussion of laser safety, please refer to section Laser safety (p. 1-2).
When APR is activated, the total pump power is decreased to below the threshold for a
class 1M laser product. For a detailed discussion of the detection mechanisms and
scenarios that lead to activation of APR, see Automatic power reduction (APR) (p. 2-5).
OSC modulation detection enables the RA3P Raman amplifier to respond to a fiber break
or connector opening which requires APR activation.
Additional RA3P Raman amplifier features
Gain flattening
Pumping the transmission fiber with two different wavelengths provides gain flattening
over C band that is better than 1.2dB peak-to-peak.
The ratio between the powers for each pump wavelength is set according to the type of
transmission fiber specified. This ratio can be fine tuned by the user.
Small polarization dependent gain (PDG)
Because the pump wavelength differs from the signal wavelength by less than 100nm, a
residue correlation between pump and signal wavelengths exists. This phenomenon is
mostly exhibited in co-propagating pumping. A polarization dependent gain (PDG) of
better than 0.3dB is achieved by using a three pump configuration, with up to 700mW
pump power, where two of the pumps have the same wavelength, but are orthogonal in
their polarization. With no polarization multiplexing, using only two pumps with different
wavelength and output power up to 450 mW, the PDG is greater than 0.6dB.
Network ready communications
The RA3P Raman Amplifier is controlled using SNMP via a standard RJ-45 Ethernet
LAN connector. The unit is supplied with a Graphical User Interface (GUI) that can be
installed on any computer connected to the LAN, or a remote computer with network
access to the LAN.
Redundant hot-swappable fans
The RA3P Raman Amplifier contains four hot-swappable cooling fans. Three of the fans
are sufficient to keep the unit within operating temperature limits. The fourth fan provides
redundant cooling capacity.
The cooling fans can be accessed and replaced through the upper covers of the unit.

Software Download
Operating software can be replaced or upgraded while the RA3P Raman amplifier is
operating without interrupting traffic passing through the amplifier, or degrading its gain.
The Software Download can be performed from a remote site via the system management
station, or through the RS232 connector on the RA3P Raman front Panel.
Automatic power reduction (APR)
Purpose
The RA3P Raman amplifier emits invisible laser radiation through the line port that can
produce eye and skin damage, as well as damage to optical and electronic equipment.
Please refer to Laser safety (p. 1-2) for detailed laser safety information.
During normal operation, when the RA3P Raman amplifier is connected through the line
port to a closed fiber transmission line, the amplifier may emit up to 700 mW of radiation.
This radiation is enclosed within the transmission line, and does not pose a hazard.
However, a hazard can occur when a fiber break or connector opening occurs. To manage
this, the RA3P Raman Amplifier is equipped to use OSC to detect a fiber break or
connector opening, and activate the APR of the RA3P Raman pumps reducing output
power to below the level defined for class 1M laser products.
This system level protection deals with operation of the amplifier within a communication
system. When this system level protection is enabled, it allows the entire system to be
classified as a class 1M system according to IEC 60825-2:1993+A1:1997+A2:2001.
OSC detection
The RA3P Raman amplifier continuously monitors the OSC signal. Loss of the signal
indicates an open connector or fiber break.

When a single direction is cut on a span containing Raman amplifiers, the Raman
amplifier on the node ingress from span where there is fiber cut (Raman [B]), will see
OSC loss. Its pumps will be turned off. However, Raman (A) on the side where there is
no fiber cut, does not see OSC loss and does not turn the pumps off. Raman packs are
completely dependent on OSC loss for APR.
APR scenarios
The OSC, identified in OSC (p. 2-3), is used to detect various scenarios that require the
activation of product and system level APR. Some scenarios are specific to either
backward counter propagating configuration (BWD), or forward co-propagating
configuration (FWD), the rest are relevant to both configurations.
OSC can be configured by the user according to the specifics of the transmission system
within which the RA3P Raman amplifier is installed.
The Alcatel-Lucent RA3P Raman amplifier is designed for backward operation only. The
relevant APR scenarios are shown in the following table.
Table 2-1 APR scenarios

LOS on Line Input (C Band). If input to amplifier < -45 dBm the
amplifier shuts down and cannot restart until input > -42dBm.
8 OSC Loss
If the modulated OSC signal (1500-1520nm) power < -43dBm the
amplifier shuts down. The amplifier can restart if the modulated OSC
signal power > -42dBm.
7OSC Band Low
Power
If optical power in OSC band (1500-1520nm) is 2dB lower than value
anticipated for the given fiber type, the amplifier shuts down.
5OSC Band
Transient
If back reflection power in OSC Band is changed by a rate faster than >
1dB/150 msec, shut down occurs.
Automatic return from APR shut down
Two possible scenarios can automatically restart the RA3P :
1. When the RA3P detects a modulated OSC signal with power > -42dBm.
2. When the RA3P detects continuous wave (CW) power in OSC band > -52dBm.
If the RA3P turns on, and one of the reasons for APR still exist, it will shut down again
within 150 msec.

Replacing a fan
The RA3P Raman amplifier has a redundant power supply and redundant fans. If one of
the power supplies or fans malfunctions, a system management alarm is received. The
power supplies are not field replaceable, but a malfunctioning fan can be replaced.
Fan replacement
Use the following procedure and illustrations to replace a fan.
...................................................................................................................................................................................................
1 Refer to the GUI error message (as shown in Figure 3-3, Fan failure indication (p. 3-13)
), or the EMS through SNMP, to determine which fans need to be replaced. The GUI
shown in Figure 3-3, Fan failure indication (p. 3-13) indicates that fans 1 and 4 have
failed.
