GPIM-08 Reference Sheet

The GPIM-08 Gigabit Ethernet Port Interface Module is a single-mode fiber-optic interface device that can be installed into an
Enterasys Networks device that supports Enterasys Networks Gigabit Ethernet Port Interface Modules. Check the documention of your
host device to see if it will support the GPIM-08.

FEATURES/SPECIFICATIONS

Refer to Table 1 for the GPIM-08 features and optical specifications.

SAFETY INFORMATION

CLASS 1 LASER TRANSCEIVERS

THE GPIM-08 GIGABIT ETHERNET INTERFACE MODULE USES A CLASS 1 LASER TRANSCEIVER. READ THE

FOLLOWING SAFETY INFORMATION BEFORE INSTALLING OR OPERATING THIS MODULE.

The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This control loop eliminates the need for maintenance checks or
adjustments. The output is factory set, and does not allow any user adjustment. Class 1 laser transceivers comply with the following safety standards:

• 21 CFR 1040.10 and 1040.11 U.S. Department of Health and Human Services (FDA).

• IEC Publication 825 (International Electrotechnical Commission).

• CENELEC EN 60825 (European Committee for Electrotechnical Standardization).

When operating within their performance limitations, laser transceiver output meets the Class 1 accessible emission limit of all three standards. Class 1 levels of laser
radiation are not considered hazardous.

SAFETY INFORMATION

CLASS 1 LASER TRANSCEIVERS

LASER RADIATION AND CONNECTORS

When the connector is in place, all laser radiation remains within the fiber. The maximum amount of radiant power exiting the fiber (under normal conditions) is -12.6
dBm or 55 x 10

-6

watts.

Removing the optical connector from the transceiver allows laser radiation to emit directly from the optical port. The maximum radiance from the optical port (under
worst case conditions) is 0.8 W cm

-2

or 8 x 103 W m2 sr-1.

Do not use optical instruments to view the laser output. The use of optical instruments to view laser output increases eye hazard. When viewing the output
optical port, power must be removed from the network adapter.

1. The maximum drive distance (up to 70 km) depends on the quality of the installed single-mode fiber-optic cable segment. Use the link power
budget (22 dB) to calculate the maximum cable length of the attached segment. The link power budget must not exceed 22 dB as specified in this
table. When using cable lengths less than 50 km, ensure that the cable has at least 3 dB of attenuation. The GPIM-08 input power must not exceed

-3 dBm. Otherwise, saturation could occur.

Cable Type 10 µm SMF

Maximum Input Power -3 dBm

1550 nm wavelength Transmit Power 0 dBm minimum +5 dBm maximum

Duplex SC style fiber-optic connector Receive Sensitivity -22 dBm

Full Duplex only Link Power Budget 22 dB

These specifications meet or exceed IEEE 802.3 1000BASE-LX requirements.
