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.
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
