CLASS 1 LASER TRANSCEIVERS

THE DELHE-UA GIGABIT ETHERNET MODULES USE

CLASS 1 LASER TRANSCEIVERS. READ THE FOLLOWING

SAFETY INFORMATION BEFORE INSTALLING OR OPERATING

THESE ADAPTERS.

The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This
control loo p elimina te s the need for mainte nance chec ks or adjust me nts . The outp ut is f acto ry 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 Publicatio n 825 (Intern atio nal Electro tec h nical Co mmi s sion).

• CENELEC EN 60825 (European Committee for Ele ctrotechnical Standardization).
When operating w it hi n their performance li mitations, laser transceiver output meets the Class 1

accessible emission limit of all three standard s. C lass 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 w ithin the fiber. The maximum amount of
radiant power exiting the fiber (un der normal conditions) is -12.6 dBm or 55 x 10

Removing the optical connect or from the trans ceiver 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

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

Only qualified personnel should perform installation
procedures.

Fast Ethern et (Po rt ) Int erfa ce Modules (FEPIMs) must be installed in the
DELHE-UA before installing the DELHE-UA in the host device. The
FEPIMs provide conne ctivit y to the networ k. At le ast on e FEPIM must be
installed in either port one or port two. To install an FEPIM in the
DELHE-UA, proceed as f ollows:

The DELF3-UI uses Class 1 lasers. 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.

The FEPIM and the DELHE-UA are sensitive to static
discharges. Use an antistatic wrist strap and observe all static

!

precautions during this procedure. Failure to do so could
damage the FEPIM or the DELHE-UA.

1. Remove the coverplate from the port slot where the FEPIM will be

installed.
To remove the coverplate, refer to Figur e 2-1 and proceed as follows:
a. Remove the two screws fastening the coverplate to the standoffs.

Save the screws.

b. Lift and remove the coverplate from the top of the front standof fs.

cable or twisted pair cable . The media chosen deter mines which type of
FEPIM to be used. When using fiber optic cable, use either the
DELFX-UI or the DELF3-UI. The DELFX-UI is used for multimode
fiber cable, and the DELF3-UI is used for single mode fiber cable. Refer
to Appendix B for details on which FEPIM to use with the appropriate
fiber optic cable. To connect to the network using fiber optic cable, refer
to Section 2.4.1. When using twisted pair cabling, use the DELTX-UI. To
connect to the network using twisted pair cab le, refer to Section 2.4.2.

2-8 DELHE-UA User’s Guide

Connecting to the Network

2.4.1 Connecting a Fiber Optic Segment to the FEPIM

DIGITAL offers fiber optic cab les that use SC style connectors which are
keyed to ensure proper crossover of the transm it and receive fibers.

An odd number of crossovers (preferably one) must be
maintained between like devices so that the transmit port of
one device is connected to the receive port of the other device
and vice versa.

If the fiber optic cable being used has SC style connectors that
do not resemble MIC style connectors, or has SC connectors
on one end and a different type on the other, such as ST
connectors, ensure that the proper crossover occurs.

1. Remove the protective covers from the fiber optic ports and f rom the

ends of the connectors.

Leave the protective covers in place when the connectors are
not in use to prevent contamination.

Certain FEPIMs use Class 1 lasers. 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.

DELHE-UA User’s Guide 2-9

Chapter 2: Installation

Do not touch the ends of the fiber optic strands, and do not let
the ends come in contact with dust, dirt, or other contaminants.

!

Contamination of the ends causes problems in data
transmissions. If the ends become contaminated, blow the
surfaces clean with a canned duster. A fiber port cleaning swab
saturated with optical-grade isopropyl alcohol may also be
used to clean the ends.

2. Insert one end of the SC connector into the FEPIM.

3. At the other end of the fiber opt ic cable, attach the SC connector to the

other device.

4. Verify that a link exists by checking that the port receive LED is ON

(flashing amber, blinking green, or solid green). If the receive LED is
OFF and the transmit LED is not blinking amber, perform the
following steps until it is ON:

a. Check that the power is turned on for the device at the other end

of the link.

b. Verify proper crossove r of fib er strands between the port on the

DELHE-UA and the fiber optic devi ce at the other end of the fiber
optic link segment.

c. Verify that the fiber connection meets the dB loss specifications

outlined in Appendix B.

If a link has not been established, refe r to Chapter 3, LANVIEW LEDs,
before contacting a DIGITAL representative.

2.4.2 Connecting a Twisted Pair Segment
