1x9 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.
Small Form Factor Transceiver
Short wavelength and long wavelength small form factor transceivers allow normal data transmission on the optical
link when they are connected to another compatible laser product. Short wavelength and long wavelength small form
factor transceivers embedded in Emulex host adapter are non-OFC. For non-OFC links, a compatible laser device
must be non-OFC and certified as a Class 1 laser product.
Any system level product that incorporates the small form factor transceivers must provide power supply protection
that guarantees a voltage of 5.0 volts or less at the small form factor transceivers. The functional power supply range
of the small form factor transceivers product is specified as 3.135 to 3.465V typically. Operation outside of this range
may degrade the performance and lifetime of the transceiver. The transceiver will remain operational with laser
emissions below Class 1 limits provided the power supply level at the adapter remains at or below 5.0 volts. If the
power supply level rises above 5.0 volts, the small form factor transceiver cannot be guaranteed to operate correctly
and could result in laser emissions that may exceed Class 1 limits.
System Level Certification
All GLMs and GBICs sold as accessories by Emulex or host adapters containing embedded 1x9 or small form factor
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, 1x9 or small form factor 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,
1x9 or small form factor transceiver, and the system level documentation and labeling. Copies of the certificate of
conformity for any GLM, GBIC, 1x9 or small form factor transceiver sold by Emulex can be obtained upon request
from Emulex Corporation, Costa Mesa.
