Usage Restrictions
Failure to comply with these usage restrictions may result in incorrect operation of
the system and could possible lead to points of access that may emit laser radiation
levels above the Class 1 limits established in the U. S. by the DHHS and within
Europe by EN60825-1/EN60825-2.

GLM
The GLM is designed and certified for applications using point-to-point optical fiber
links only. Use of the product with multiple input or multiple output optical links (for
example, star couplers) is prohibited since it is incompatible with the GLM’s
certification.
The GLM will not allow normal data transmission on the optical link unless it is
connected to another similar GLM or compatible laser product. For OFC GLMs,
another manufacturer’s laser product is not considered compatible unless it contains
the open fiber link detection and laser safety control system (OFC) and is properly
certified as a Class 1 laser product. Similarly, for non-OFC GLMs, a compatible
laser device must be non-OFC.
Any system level product that incorporates the GLM must provide power supply
protection that guarantees a voltage of 6.0 volts or less at the GLM. The functional
power supply range of the GLM product is specified as 4.75 to 5.25 volts typically.
Operation outside of this range may degrade the performance and lifetime of the
GLM. The GLM will remain operational with laser emissions below Class 1 limits
provided the power supply level at the adapter remains at or below 6.0 volts. If the
power supply level rises above 6.0 volts, the GLM cannot be guaranteed to operate
correctly and could result in laser emissions that may exceed Class 1 limits.
GBIC
Short wavelength and long wavelength GBICs allow normal data transmission on
the optical link when they are connected to another compatible laser product. Short
wavelength and long wavelength GBICs sold by Emulex as accessories are non-
OFC devices. For non-OFC links, a compatible laser device must be non-OFC and
