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 the LP7000E, LP8000, LP850 or LP9000.
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
GBICs and 1270 to 1355 nanometers for long wavelength GBICs. 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
