Description
• The OPM210 power meter measures optical power
at 850 nm, 1300 nm, 1310 nm, 1490nm, 1550nm and
1625 nm between a power range of +6 to -70dBm. The
OPM210 is supplied standard with a universal 2.5mm
bulkhead. The OPM210 is supplied with a 1mW Visual
Fault Locator that is used to measure ber breaks,
discontinuities and Macrobends. The VFL has a universal
2.5mm interface with an optional 1.25mm adapter
available.
• The OPM220 power meter measures optical power
at 850 nm, 1300 nm, 1310 nm, 1490nm, 1550nm and
1625 nm between a power range of +26 to -40dBm. The
OPM210 is supplied standard with a universal 2.5mm
bulkhead. The OPM220 is supplied with a 1mW Visual
Fault Locator that is used to measure ber breaks,
discontinuities and Macrobends. The VFL has a universal
2.5mm interface with an optional 1.25mm adapter

LASER LIGHT
DO NOT STARE INTO BEAM
CLASS 2 LASER PRODUCT
The OPM210 and OPM220 instrument has a laser device, a Visual
Fault Locator (VFL) conforming to the requirements of CDRH, CFR
1040, Subchapter J. While there is no potential for eye damage due to
unaided direct exposure, users should always avoid looking directly
into the output port. The use of optical viewing instruments, such as
micro- scopes, magniers, etc., should always be avoided. The use
of such devices around active bers can focus an intense beam of
light energy onto the retina of the eye, which can result in permanent
damage.
Laser hazard:
• When performing measurements on ber optic systems, avoid eye
exposure to any open-ended bers, optical connectors, optical
interfaces, or other sources because they may be connected to
active laser transmitters.
• Do not look into the optical port when a source is turned on.
• Avoid looking at the free end of a test ber, i.e., the end not con-
nected to the instrument. If possible, direct the free end toward a
non-reective surface.
Failure to observe these precautions may result in injury.
Important Safety Information

Electric shock hazard:
• Do not insert batteries with the polarity reversed.
• Do not open the case of the unit for any reason. It contains no
user-serviceable parts.
• Use this unit for the manufacturer’s intended purpose only, as
described in this manual. Any other use can impair the protection
provided by the unit.
Failure to observe these precautions may result in injury and may
damage the unit.
Instrument damage hazard:
• Do not leave the unit in direct sunlight or near direct sources of
heat.
• Protect the unit from strong impacts or shock.
• Do not immerse the unit in water or store in areas with high
humidity.
• When necessary, clean the case, front panel, and rubber cover with
a damp cloth. Do not use abrasives, harsh chemicals, or solvents.
• Replace the interface dust cap(s) when the unit is not in use.
• Store the unit and interface adapters in a cool, dry, and clean place.
Failure to observe these precautions may result in injury and may
damage the unit.

To replace the batteries, follow these steps:
1. Turn instrument off.
2. Remove battery cover.
3. Install the new batteries observing correct polarity as
below.
Connector Interface
Both the OPM and VFL ports are universal 2.5mm. A 1.25mm
adapter is available as an optional accessory.
Cleaning the OPM and VFL Interfaces
Make sure that the instrument is powered off.
Do not look into the output of any ber port.
Use a new 2.5mm cleaning swab each time to clean each
bulkhead port.
