AFL OFL250 - Safety Information

4
WARNING! Use of procedures or adjustments other than those specified herein may result in
hazardous radiation exposure.
1310/1550 nm
single-mode OTDR /OLS
port
This is a CLASS I LASER output
VFL port This is a CLASS II LASER output.
Do not stare into beam
WARNING! Do not connect the OTDR to any fiber that is not dark, or that is terminated by a
device with reflectivity > -13 dB.
CAUTION! To avoid serious eye injury, never look directly into the optical outputs of fiber optic
network equipment, test equipment, patch cords, or test jumpers. Refer to your company’s
safety procedures when working with optical systems.
WARNING! Use only the specified AC adapter. Use of another type of AC adapter can damage
the instrument and create the danger of fire and electrical shock.
WARNING! To avoid the danger of fire and electrical shock:
• Never use a voltage that is different from that for which the AC adapter is rated.
• Do not plug the unit into a power outlet that is shared by other devices.
• Never modify the power cord or excessively bend, twist, or pull it.
• Do not allow the power cord to become damaged. Do not place heavy objects on the power
cord or expose it to heat.
• Never touch the AC adapter while your hands are wet.
• Should the power cord become seriously damaged (internal wiring exposed or shorted),
contact the manufacturer to request servicing.
CAUTION! Do not connect the OFL250 OTDR test port to a live fiber.
If you are not certain that the fiber to be tested is ‘dark’ (not live), measure the optical power
level of the fiber before connecting to the OFL250 OTDR port. Use a jumper to connect the
OFL250 OPM test port to the fiber to be tested, set the OFL250 test mode to OPM with units set
to dBm. If the detected level is above -20 dBm, do not connect this fiber to the OFL250 OTDR
test port. Connecting the OFL250 OTDR test port to a live fiber can cause a bad trace or in the
worst case, damage the OTDR.
NOTICE: An OFL250 OTDR contains no user serviceable parts. Except for changing batteries
and cleaning optical ports, this instrument must be returned to NOYES or authorized agents for
repair and calibration.
IMPORTANT: Proper care in handling should be taken when using any precision optical test
equipment. Scratched or contaminated optical connectors can impact the performance of the
instrument. It is important to keep the dust caps in place when the unit is not being used.
