In the United States, all optical GLMs, GBICs, 1x9 and small form factor transceivers sold by Emulex are certified as
Class 1 laser products that conform to the requirements contained in the Department of Health and Human Services
(DHHS) regulation 21 CFR subchapter J. The certification is indicated by a label located on the optical GLM, GBIC,
1x9 or small form factor transceiver.
In Europe, all optical GLMs, GBICs, 1x9 and small form factor transceivers sold by Emulex are certified as Class 1
laser component assemblies that conform to the requirements contained in the CENELEC (European Committee for
Electrotechnical Standardization) standard EN60825-1:1994 (including amendment 11) and EN60825-2:1994.
GLMs, GBICs, 1x9 and small form factor transceivers are certified by a recognized European testing agency and have
appropriate markings on the assembly. The DHHS conformity label and European conformity mark will not be
visible externally once the optical GLM, GBIC, 1x9 or small form factor transceiver is connected to or inserted in the
host adapter and the adapter is installed into a system.
Labeling Requirements
No caution or danger labels are required for use of the GLM, GBIC, 1x9 or small
form factor transceiver since they are Class 1 laser component assembly. In the
U.S., the only laser safety label required is the DHHS certification label that
already appears on the GLM, GBIC, 1x9 and small form factor transceiver. In
Europe, the EN60825-1/EN60825-2 standards require that the system-level
product has a Class 1 information label permanently attached and clearly visible
whenever access to the GLM, GBIC, 1x9 and small form factor transceiver optical port is possible. Each Class 1
product shall have affixed an explanatory label bearing the words:
Alternatively, at the discretion of the manufacturer, the same statement may be
included in user information. If a label is used, an example of the IEC Class 1
information label that is suitable for most European countries is shown below. The
label consists of black printing on a white background. Languages represented on
this label are English, German, Finnish and French, and they represent the
minimum set for acceptance of a Class 1 product in most European countries.
Product Information
GLM
The optical GLM is a single port communications card. Each communication port consists of a transmitter and
receiver optical subassembly. The transmitter subassembly contains a semiconductor laser diode of gallium
aluminum arsenide (GaAlAs). This material emits in the wavelength range of 770 to 860 nanometers for shortwave
and 1270 to 1355 nanometers for long wave, and are commonly referred to as short wavelength (SW) or long
wavelength (LW) lasers. The discrete laser diodes are classified as Class 3B laser products. Once they are
incorporated into the GLM, the product’s automatic power control maintains the average power launched into a fiber
at a value below the Class 1 limit.
Note: OFC GLMs are found only on the LP6000. Any reference to OFC or non-OFC products applies
only to the LP6000, and not to other HBA models.
For OFC GLMs (Open Fiber Control) the optical fiber link between two GLM ports is continuously monitored by the
open fiber link detection and laser safety control system (OFC). In the event of a break anywhere in the path, this
control system prevents laser emissions from exceeding Class 1 levels. For non-OFC links, the optical power from the
laser transmitter is controlled and maintained at a lower power level. The power emitted from either an open fiber or
open laser transmitter is guaranteed to be below the Class 1 limit. Class 1 laser products are not considered hazardous.
No user maintenance, service operations or adjustments can be performed on any GLM accessory.
GBIC
The optical GBIC is an integrated duplex data link for bi-directional communications over multimode or single mode
optical fiber. Each GBIC consists of a transmitter and receiver optical subassembly. The transmitter subassembly
contains a semiconductor laser emitting in the wavelength range of 770 to 860 nanometers for shortwave length
