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 certified as a Class 1 laser product.
