Optical Connector Care and Handling
All optical connectors are shipped with end caps for protection and safety. Do not
remove the end caps until installation.
The optical connector’s surface is highly polished and free of foreign materials to
ensure low loss coupling and back reflection. Do not allow the optical connectors to
become dirty. Small traces of dirt will degrade transmission quality. Ensure that the
caps are on the optical connectors at all times.
It is absolutely critical that fiber optic connectors be cleaned each and every time
before connecting or reconnecting to anything.
Without proper maintenance practices, fiber optic systems will fail to function
properly. These performance degradation’s take many forms:
• Poor analog transmission quality
• Digital bit error rates increase
Operating Manual OptiCaT 1500 Erbium-Doped Fiber Amplifier
1-3
• Reduced optical power
• Receiver input power outside optimum operating range
• Dirty connectors may cause damage to their mated counterparts
It is recommended that RIFOCS Corporation 945/946 fiber optic connector cleaning
system be used for cleaning the optical connectors.

Startup and Normal Operation
With the Laser key in the “Off” position, turn on the rear panel electrical power.
When the EDFA is first powered up, it will go through a series of power-on selftests. During the self-test period, the push buttons are disabled, the display flashes
“Start-up,” and the LED is set to amber.
With the key in the “Off” position, the optical gain will be disabled and the input
optical signal will be throughput without any amplification or degradation.
To enable the optical gain section, turn the key switch to the “On” position. The
LED will switch to green and “1550 EDFA” will be displayed. If the EDFA does
not pass its self-test because of a warning or an alarm condition, then the EDFA
3-2
Operating Manual OptiCaT 1500 Erbium-Doped Fiber Amplifier
changes the LED and display as described in table 4-1 in Section 4
Troubleshooting.
During normal operation, the EDFA displays “1550 EDFA.” When the “select”
button is pressed, the display changes to show system information according to the
menu structure of Fig. 3-1. By repeatedly pressing “select,” the display cycles
through the menu headings “Optical,” “Pump 1,” “Pump 2,” on up to “Pump 4 if
installed,” and “System.”
In EDFA’s where fewer pumps are installed, the menu headings for those lasers not
installed are eliminated. The down button moves the display down in the menu
structure; if the bottom of the menu is reached, the display wraps back to the top.
For instance, if “Pump 1” is shown and the down button is pressed, then the display
shows the pump 1 laser bias current. The up button moves the display up the menu
structure.
3.4
Output Power Adjustment
To adjust the output power repeatedly press the “select” button until the “Optical”
menu heading appears in the display. Press the down button until the display reads
“Pwr Adj = xx.xdBm.” Press the “select” button and the display will start to flash.
Use the up and down button to adjust the power to the desired setting. Press the
select button again to save the adjustment.
Press the down button again, and the display will read “Update Adj. = Y/N.” Press
the select button and the display will start to flash. Use the up/down buttons to
select “Y” or “N.” Press the select button again to save your choice. If “Y” is
chosen, the adjusted power setting will automatically come up each time the unit is
turned on. If “N” is chosen, the power setting will change back to the previously
updated value when power to the unit is cycled.

TROUBLESHOOTING
There are two types of faults - warnings and alarms. Warnings are conditions that
indicate problems, but do not necessarily result in a total loss of service. Alarms are
conditions that indicate a total loss of service. Based on the condition of the alarm or
warning, different indicators will be affected. These are described below.
4.1
Warning Conditions
When the EDFA is in the warning condition, the status LED will change to amber,
and a brief description of the condition is listed on the display. Warnings generally
do not halt operation of the unit, but correspond to a parameter that is slightly out
of range. If the warning condition ceases, i.e. , the relevant parameter goes back
into its allowable range, the display and LED will return to their normal state
without user intervention.
4.2
Alarm Conditions
Alarms generally halt operation of the EDFA. They correspond to either a
parameter that is far out of the acceptable range, or to a condition that could
potentially cause damage to the EDFA. If the alarm persists after cycling power or
toggling the keyswitch, then the alarm is activated again.
Table 4-1 defines the different warning and alarm conditions, the display readout,
and how the conditions are cleared. Some critical alarms, such as “Alarm: self
test,” can only be cleared by cycling power to the EDFA. Other alarms are cleared
when the keyswitch is toggled off and then on again or are self clearing if the
relevant parameter returns to a normal range. With warnings, the EDFA will
simply continue to function while indicating the warning, or the warning will clear
itself if the relevant parameter returns to a normal range.

THEORY AND BLOCK DIAGRAM
The OptiCaT 1500 EDFA block diagram is shown in Fig 5-1. Depending on model,
isolators are used at both the input and output to prevent optical reflections from feeding
back into the amplifier which can degrade performance. Tap couplers at both the input and
output are used to monitor the power of the incoming and amplified output signal.
Gain occurs in a section of Erbium doped fiber which is “pumped” by light from 980 nm
lasers. The erbium ions absorb the 980nm pump light and re-emit light which is in phase
and at the same wavelength as the input signal. The amount of gain is dependent on both
the incoming signal power and the pump power.
