SAFETY INFORMATION

CLASS 1 LASER TRANSCEIVERS

CLASS 1

LASER PRODUCT

Class 1 Laser Products

The FDMMIM-30 connectors use Class 1 Laser transceivers. Read

the following safety information before installing or operating the

FDMMIM-30.

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.

FCC NOTICE

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 -12.6dBm or 55x10 -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 8x10 3 W m-2 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, you must remove power from the

network adapter.

INTRODUCTION

CHAPTER 1

INTRODUCTION

The FDMMIM, FDMMIM-04, FDMMIM-24, and FDMMIM-30

combine the functions of an FDDI concentrator with those of an

Ethernet/802.3 to FDDI bridge. When distinguishing one module

from the other, keep the following in mind:

• All modules contain FDDI A and B ports which bridge to a

Multi Media Access Centerhub Ethernet bus.

• The FDMMIM-04 and FDMMIM-24 also contain four M type

concentrator ports.

• The master ports of the FDMMIM-24 are unshielded twisted

pair connections.

• The FDMMIM, FDMMIM-04, and the FDMMIM-24 A and B

ports are multimode fiber optic devices.

• The FDMMIM-30 is a single mode fiber optic module that

uses a class 1 laser. This laser increases the link length from

the multimode maximum drive distance of 2 kilometers (km)

to a single mode maximum of 40 km.

This manual describes how to install the FDMMIM, FDMMIM-04,

FDMMIM-24, and FDMMIM-30 and explains how to use the on-

board management tool, FDMMIM Local Management, to configure,

monitor, and control the bridge/concentrator.

Unless otherwise noted, the term FDMMIM refers to the FDMMIM,

FDMMIM-04, FDMMIM-24, and FDMMIM-30. In addition, the

terms FDMMIM/LM, Local Management, and LM refer to FDMMIM

Local Management.
