Handling, safety, and environmental guidelines

Before you install a GBIC, SFP, or XFP, read the following handling, safety,
and environmental guidelines:

•

GBICs, SFPs, and XFPs are static sensitive. To prevent damage from
electrostatic discharge (ESD), see "Electrostatic discharge prevention"

(page 11).

11

•

GBICs, SFPs, and XFPs are dust sensitive. When you store a GBIC,
SFP, or XFP, or when you disconnect it from a fiber optic cable, always
keep a dust cover over the GBIC, SFP, or XFP optical bore.

•

To clean contaminants from the optical bores of a GBIC, SFP, or XFP,
use an alcohol swab or equivalent to clean the ferrules of the optical
connector.

•

Dispose of this product according to all national laws and regulations.

Electrostatic discharge prevention

To prevent equipment damage, observe the following electrostatic discharge
(ESD) precautions when handling or installing the components.

•

Ground yourself and the equipment to an earth or building ground. Use
a grounded workbench mat (or foam that dissipates static charge) and
a grounding wrist strap. The wrist strap should touch the skin and be
grounded through a one megaohm resistor.

12 Safety and regulatory information

•

Do not touch anyone who is not grounded.

•

Leave all components in their ESD-safe packaging until installation, and
use only a static-shielding bag for all storage, transport, and handling.

•

Clear the area of synthetic materials such as polyester, plastic, vinyl, or
styrofoam because these materials carry static electricity that damages
the equipment.

Care of fiber optic equipment

Fiber optic equipment must be kept clean and damage-free. Use the
information in this section to properly maintain and care for fiber optic
equipment.

Fiber optic cable care

Although the glass fiber of fiber optic cable is protected with reinforcing
material and plastic insulation, it is subject to damage. Use the following
precautions to avoid damaging the glass fiber.

•

Do not kink, knot, or vigorously flex the cable.

•

Do not bend the cable to less than a 40 mm radius.

•

Do not stand on fiber optic cable; keep the cable off the floor.

•

Do not pull fiber optic cable any harder than you would a cable containing
copper wire of comparable size.

•

Do not allow a static load of more than a few pounds on any section
of the cable.

•

Place protective caps on fiber optic connectors that are not in use.

•

Store unused fiber optic patch cables in a cabinet, on a cable rack, or
flat on a shelf.

Frequent overstressing of fiber optic cable causes progressive degeneration
that leads to failure.

If you suspect damage to a fiber optic cable, either due to mishandling or
an abnormally high error rate observed in one direction, reverse the cable
pairs. If the high error rate appears in the other direction, replace the cable.

CAUTION

Do not crush fiber optic cable. If fiber optic cable is in the same
tray or duct with large, heavy electrical cables, it can be damaged
by the weight of the electrical cable.

Fiber optic connector care

Before connecting them to transmission equipment, test equipment,
patch panels, or other connectors, clean all fiber optic connectors. The
performance of an optical fiber connector depends on how clean the
connector and coupling are at the time of connection. Use the following
cleaning procedures when analyzing fiber connector integrity.

If a connector performs poorly after cleaning, visually inspect the connector
to determine the possible cause of the problem and to determine if it needs
replacing.

Care of fiber optic equipment 13

WARNING

Do not look into the end of fiber optic cable. The light source used
in fiber optic cables can damage your eyes.

To avoid getting debris in your eyes, wear safety glasses when
working with the canned air duster.

To avoid eye irritation on contact, wear safety glasses when
working with isopropyl alcohol.

Perform the following maintenance procedures to ensure that optical fiber
assemblies function properly. To prevent them from collecting dust, make
sure connectors are covered when not in use.

CAUTION

To prevent further contamination, clean fiber optic equipment only
when there is evidence of contamination.

To prevent contamination, make sure the optical ports of all active
devices are covered with a dust cap or optical connector.

To avoid the transfer of oil or other contaminants from your fingers
to the end face of the ferrule, handle connectors with care.

CWDM SFPS are also supported. CWDM technology consolidates
multiple optical channels on a common optical fiber. CWDM uses multiple
wavelengths to expand available bandwidth.

CWDM SFPs are designed to support high speed data communications
for Metropolitan Area Networks (MANs). The system uses a grid of eight
CWDM optical wavelengths in both ring and point-to-point configurations.
All components are color-coded by wavelength.

ATTENTION

The attainable cable length can vary depending on the quality of the fiber optic
cable used.

Procedure job aid: SFP models with DDI support

Digital Diagnostic Monitoring (DDM) allows the Metro Ethernet Routing
Switch 8600 to monitor SFP laser operating characteristics. Metro Ethernet
Routing Switch 8600 support for Digital Diagnostic Interfaces (DDI—an
interface that supports DDM) involves data collection and alarm and warning
monitoring. Static data collection includes the SFP vendor information, DDI
support information, and DDI alarm and warning threshold values. Dynamic
data collection includes temperature, supply voltage, laser bias current,
transmit power, and receive power. DDM works at any time during active
laser operation without affecting data traffic.

The warning and alarm status bits are only checked during initialization
and during requests for dynamic data. If an alarm or warning is asserted
or cleared, a message is logged and a trap is generated. DDM warning

and alarm messages are mapped into WARNING and FATAL message
categories for system logging purposes. If an alarm or warning is generated,
the software does not automatically shut down the port.

CWDM SFPs are also supported. CWDM SFPs are designed to support
high-speed data communications. A CWDM system uses a grid of
wavelengths to provide multiple channels for both ring and point-to-point
configurations. All components are color-coded by wavelength.

Any DDM SFP can be used in any Metro Ethernet Services Unit 1800 or
1850 device or Metro Ethernet Routing Switch 8600 module that supports
SFPs. The optical functions of the SFP are supported. Access to the DDI
information is only provided for:

•

Metro ESU 1850

•

Metro Ethernet Routing Switch 8600 modules 8630 and 8683

Access to DDI information is not supported for:

•

Metro ESU 1800

•
