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.
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.
