Caution: Only qualified technicians should install this  
equipment.  
Place all printed circuit boards on an antistatic mat until you  
are ready to install them. If you do not have an antistatic  
mat, wear a discharge leash to free yourself of static before  
touching any of the printed circuit boards, or free yourself of  
static by touching a grounded metal object before handling a  
printed circuit board.

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.  
Vorsicht: Glasfaserkomponenten können Laserlicht bzw. Infrarotlicht  
abstrahlen, wodurch Ihre Augen geschädigt werden können. Schauen  
Sie niemals in einen Glasfaser-LWL oder ein Anschlußteil. Gehen Sie  
stets davon aus, daß das Glasfaserkabel an eine Lichtquelle  
angeschlossen ist.  
Avertissement: Léquipement à fibre optique peut émettre des  
rayons laser ou infrarouges qui risquent d’entraîner des lésions  
oculaires. Ne jamais regarder dans le port d’un connecteur ou d’un  
câble à fibre optique. Toujours supposer que les câbles à fibre optique  
sont raccordés à une source lumineuse.

Advertencia: Los equipos de fibra óptica pueden emitir radiaciones  
de láser o infrarrojas que pueden dañar los ojos. No mire nunca en el  
interior de una fibra óptica ni de un puerto de conexión. Suponga  
siempre que los cables de fibra óptica están conectados a una fuente  
luminosa.  
Avvertenza: Le apparecchiature a fibre ottiche emettono raggi laser o  
infrarossi che possono risultare dannosi per gli occhi. Non guardare  
mai direttamente le fibre ottiche o le porte di collegamento. Tenere in  
considerazione il fatto che i cavi a fibre ottiche sono collegati a una  
sorgente luminosa.

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 GBICs 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 color-  
coded.  
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  
intermediate CWDM OADM or CWDM OMUX.
