Handling, safety, and environmental guidelines

Before installing your GBIC, read the following handling, safety,
and environmental guidelines:

• GBICs are static sensitive. To prevent damage from
electrostatic discharge (ESD), follow your normal board
and component handling procedures.

• GBICs are dust sensitive. When you store a GBIC, or when
you disconnect it from a fiber optic cable, always keep the
dust cover over the GBIC’s optical bores.

• To clean contaminants from the optical bores of a GBIC,
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.

Warning: Fiber optic equipment can emit laser or

infrared light that can injure your eyes. Never look into
an optical fiber or connector port. Always assume that
fiber optic cables are connected to a light source.

Introduction to Coarse Wavelength Division
Multiplexed (CWDM) Small Form Factor
Pluggable (SFP) Gigabit Interface Converters

This section describes how the Nortel Networks* coarse
wavelength division multiplexed Small Form Factor Pluggable
Gigabit Interface Converter (CWDM SFP GBIC) works within
the optical routing system. It also provides a list of CWDM SFP
GBICs by wavelength and shows how they are labeled and color­coded.

CWDM SFP GBIC description

CWDM SFP GBICs are transceivers that link Gigabit Ethernet
ports with fiber optic networks. WDM technology consolidates
multiple optical channels, using specific wavelengths to expand
available bandwidth, on a common optical fiber.

About the optical routing system

CWDM SFP GBICs are a component in the optical routing
system designed to support high speed data communication 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.

Note: A minimum attenuation of 5 dB must be present

between the transmitter and receiver. To avoid receiver
saturation, you must insert a minimum attenuation of 5
dB when:

• testing the CWDM SFP GBIC in loopback mode

• using short runs of fiber with no intermediate

CWDM OADM or CWDM OMUX

To determine the expected signal loss for a CWDM
OADM, CWDM OMUX, or fiber length, see Installation
and Networking Guidelines for Optical Routing, part
number 212257-A.

Given a loss budget of 24 dB and assuming fiber loss of
.25 dB/km, up to 96 km reach is supported with no
