1. General Information
1.1 Safety Precautions
This product emits high power invisible laser radiation from the optical connector(s)
that classifies it to be a CLASS 4 laser product accordingly to IEC 60825-1:2007. The
optical output is hazardous to eyes and skin. AVOID EYE OR SKIN EXPOSURE
TO DIRECT OR SCATTERED RADIATION.
THE OPTICAL OUTPUT MUST BE DISABLED WHEN SWAPPING PATCHCORD
CONNECTIONS.
NEVER USE ADAPTOR OR CONNECTOR TYPE OTHER THAN SPECIFIED IN
THE TEST REPORT. If measurement instruments accept different connector type,
use hybrid patchcords.
Ensure the optical input signal is within the range specified in the test report.
There MUST be an input signal present before turning on the optical output.
Do NOT use this product in HIGH PEAK PULSE POWER (>10W) applications
unless with the consent from the manufacturer. Failing to following this
instruction voids the warranty.
THE OPTICAL OUTPUT IS A POTENTIAL FIRE HAZARD. It is recommended that
the product is used only in a secure and insulated environment.
Catastrophic failure (plasma formation) of optical fiber can occur at optical
powers of even less than 1 W, CW.The optical fiber can become locally heated to
high temperatures at a sharp bend or dust at a fiber end.When the fiber reaches
these high temperatures it starts to absorb the laser radiation and catastrophic failure
occurs. The high temperature failure region moves at about 1 m/stowards the source
of laser radiation. IT IS RECOMMENDED THAT AN EXTERNAL ISOLATOR OR
LONG PATCHCORD BE PERMANENTLY CONNECTED TO THE OUTPUT
RECEPTACLE TO PROTECT THE EQUIPMENT FROM BEING DAMAGED BY
THIS PHENOMENON.

In case when catastrophic failure (plasma formation) has occurred, DO NOT
enable the lasers again. Otherwise the optical fiber will continue to burn
towards the source of laser radiation at about 1m/s.
Plasma Formation (fiber on the left)
OPTICAL COMPONENTS CONNECTED TO THE OPTICAL OUTPUT MUST BE
RATED FOR HIGH POWER USE. It is highly recommended that these components
be properly cooled to dissipate heat.
FOR CONTINUED PROTECTION AGAINST FIRE, REPLACE ONLY WITH SAME
TYPE AND RATING OF FUSE.
The equipment is certified for EMC requirements. THE USER SHOULD NEVER
OPEN THE EQUIPMENT CASE; any attempt will void the warrantee and may result
in electric shock and EMI attack to equipment in the vicinity.
Avoid using any solvent or vaporizing chemical to clean the equipment panel or case.
It may result in damage to the surface and internal circuits.
