1. Product Families
Olson Technology, Inc. manufactures high performance fiber amplifiers and lasers, modules and subsystems to meet the rapidly growing demands of the communication market.
OT’s wide range of high and low power amplifiers and lasers are compact, cost-effective
and exceptionally reliable.
OT’s product innovation stems in part from a concept known as parallel pumping which
enables fiber devices to generate almost unlimited power and provides for pumping redundancy, enhanced reliability and extended lifetime of devices.
The OTEA-CM series is specially optimized for used with Direct Modulation 1550nm
Transmitters.
Key F ea tures
• Long Life Time
• Specially Designed to Operate with Direct Modulation 1550nm Transmitters
• Low Noise Figure
• High Conversion Efficiency and Low Power Consumption
• Unique Saturated Output Power
• Compact Design
• Low PMD and PDL
OTEA Rac k Mount De vices
The OTEA devices are rack mount amplifiers designed for use in standard 19-inch equipment racks. They are complete with dual universal voltage/frequency power supplies for
redundancy. The unit is controlled through menu driven front pushbuttons with an LCD
display or a standard RS-232 interface.

Laser Classification IIIb > 100mW 1550nm
This device is classified as a high power Class IIIb laser instrument under 21 CFR
1040.10. This product emits invisible laser radiation at or around a wavelength of 1550 nm,
and the total light energy radiated from any optical output is greater than 100mW. This
level of light may cause damage to the eye and skin. Despite the radiation being invisible,
the beam may cause irreversible damage to the cornea. Laser safety eyewear is not provided with this instrument, but must be worn at all times while the laser is operational.
WARNING:
Use appropriate laser safety eyewear when operating this device. The selection of
appropriate laser safety eyewear requires the end user to accurately identify the
range of wavelengths emitted from this product. If the device is a tunable laser or
Raman product, it emits light over a range of wavelengths and the end user should
confirm the laser safety eyewear used protects against light emitted by the device
over its entire range of wavelengths.
WARNING:
Use of controls or adjustments or performance of procedures other than those set
forth in this User’s Guide may result in hazardous radiation exposure.
CAUTION:
Do not install or terminate fibers when amplifier is active.

General Safety Instructions
In order to ensure the safe operation and optimal performance of the product, please follow these warnings and cautions in addition to the other information contained elsewhere
in this document.
CAUTION:
Before supplying the power to the instrument, make sure the correct voltage is
used. Failure to use the correct voltage could cause damage to the instrument.
WARNING:
Make sure this instrument is properly grounded. Any interruption of the protective
grounding conductor from the protective earth terminal can result in personal injury.
WARNING:
This device and all parts or components thereof are not meant to be operator serviced, except for the replaceable fuse(s). Refer all servicing to qualified OT personnel. To prevent electrical shock, do not remove covers or system components. Any
tampering with or disassembly of the device, parts, or components will void the
warranty and possibly expose the operator to an electrical shock hazard.
WARNING:
DC powered instruments are not meant to be attached to a power source that is capable of delivering more than 30 Amps or connected to a circuit with a 30 Amp
breaker. Failure to limit the source current to less than 30 Amps can result in operator injury, voiding of the warranty and/or instrument damage.
WARNING:
Laser radiation is emitted from all optical outputs simultaneously. Avoid exposure
from all unused optical ports.
WARNING:
Do not enable the laser when no fiber or equivalent is attached to the optical output
connector.

WARNING:
If this instrument is used in a manner not specified in this document, the protection
provided by the instrument may be impaired and the warranty will be voided. This
product must be used only in normal conditions.

Connector Cleaning Guide
Optical fiber connectors require care and careful cleaning. Caps should be left on connectors whenever they are not in use. Do not touch the connector end. Damage to connector
end faces caused by improper care is not covered by the warranty.
Equipment
We have found the following equipment useful in maintaining connector
cleanliness:
Automatic connector cleaner (CLETOP
TM
) (available from most suppliers) or canned iso-
propyl alcohol with clean optical wipes and canned air.
Connector inspection microscope. (The Noyes 300-200 or 300-400 optical fiber scope is
good, as is the AMP fiber inspection scope and the Buehler fiber scope. Typical low cost
multimode connector viewers are not suitable for inspecting single-mode connectors).
Cleaning procedure
WARNING
After making sure that the light source is off (!!!), check the connector ferrule end using
the connector inspection microscope. If no dirt, grease or small particles are visible no further cleaning is necessary.
Use canned air to remove loose particles.
Use automatic connector cleaner such as CLETOP
Either
connector slightly. Using an automatic cleaner is our preferred technique. Note that some
low cost cleaners may leave small particles on the fiber surface.
directed on the box. Be careful with angled connectors (connectors with green
boots) to make sure the full surface contacts the cloth. You will need to tilt the
:
TM
. Wipe the connector as
Moisten a clean optical wipe with alcohol and wipe connector. Finish by wiping
Or
the connector with a dry part of the wipe. Be careful not to allow oil from fingers to
contact connector. Allow the connector to dry for 1 minute. Inadequate drying can
result in the alcohol residue burning into the connector end when the fiber is lit.
Inspect the connector ferule under the microscope. Clean again if necessary.
If a connector is to be used to transmit high powers (>50mW), great care should be taken
in cleaning. Mating loss of these connectors should be kept to a minimum.

Bulkhead cleaning
Fiber bulkhead adapters contain a zirconia or phosphor-bronze sleeve. After removing the
connectors, these can be cleaned with a pipe cleaner moistened with isopropyl alcohol,
and dried with canned air.
Troubleshooting
A small black area appears in the middle of the connector which cannot be removed by
cleaning.
Some material (typically oil from skin contact, residue alcohol or particles from connector
cleaning devices) has burnt on the connector surface. Do not use your device and contract
OT for assistance.
A small circle of dried droplets are visible on the end of the connector.
The connectors were mated when one was still wet (typically from water/alcohol). Repeat
cleaning procedure.
The connector is clean but the loss on mating varies by 10dB or more.
Check to see if the bulkhead adapter sleeve is cracked. Be careful not to over-tighten connectors.
A gray powdery grime continues to appear on the connectors after repeated mating.
If the bulkhead adapter sleeve is made from phosphor-bronze, some of the metal is
probably rubbing off on the connectors.

Protecting Your De vice from Optical Connector
Damage
Output powers of 1 Watt or less
CAUTION:
High optical powers can burn oil from fingerprints, dirt, dust or cleaning alcohol into
the connector ends. The resulting damage looks like a black dot in the middle of the
connector end-face and is clearly visible under a connector viewer microscope. If
you are using an amplifier for component testing, we recommend following the
"Connector cleaning guide" section (above).
If connectors are being frequently connected and disconnected, occasional connector contamination is likely. Large numbers of connector mating are common in a manufacturing
setting where hundreds of parts are being power tested.
