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.
1 x 9 Transceiver
Short wavelength 1x9 transceivers allow normal data transmission on the optical link when they are
connected to another compatible laser product. Short wavelength 1x9s embedded in Emulex host adapters
are non-OFC. For non-OFC links, a compatible laser device must be non-OFC and certified as a Class 1
laser product.

System Level Certification
All GLMs and GBICs sold as accessories by Emulex or host adapters containing embedded 1x9 transceivers are
certified as Class 1 laser products within the U.S. and Class 1 laser component assemblies outside of the U.S.
Manufacturers of products properly incorporating the GLM, GBIC or 1x9 transceiver do not need to recertify
their product for laser safety. The procedure for full system certification is therefore identical to that used for any
other electronic system. When applying for system level certification to electronic standards such as IEC950, the
regulatory engineers may want to see the DHHS and European conformity labeling on the GLM, GBIC or 1x9
transceiver, and the system level documentation and labeling. Copies of the certificate of conformity for any
GLM, GBIC or 1x9 transceiver sold by Emulex can be obtained upon request from Emulex Corporation, Costa
Mesa.
