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 abstr a hle n , wodurch Ihre Augen geschäd igt w erd e n können. Sch au e n Sie niemals in einen Glasfaser-LWL oder ein Anschlußteil. Gehen Sie stets davon aus, daß das Glasfaserkabel an eine Lichtquelle angesc hlossen i st .

Avertissement: L’équipement à fibre optique peut émettre des rayons laser ou infrarouges qui risquent d’e ntraîn e r des lésions oculaire s. Ne jamais regarder dans le port d’un connecteur ou d’un câble à fibre optique. Toujou rs supposer que les câbles à fibre optiqu e 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 interio r 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 rag gi 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.

Introduction

This sect ion describes how the Nortel N etworks * coarse wavelength division multiplexed Gigabit Interface Converter (CWDM GBIC) works within the optical routing sys tem. It als o provide s a list of CWDM GBICs by wavelength and shows how they ar e labeled an d color-code d .

CWDM GBIC description

CWDM GBICs are transceivers that link Gi gabit Eth ernet port s with fib er optic ne tw orks. WDM technology consolidates multiple optical channels, using spe cific wavelengths to expand availa ble bandwid th, on a common optical fiber.

About the optical ro uting system

CWDM GBICs (Figure 1) are a componen t in th e opt ic al rout in g system designed to support high speed data comm unication for Metropolitan Area Networ ks (MANs). The system uses a grid of eight CWD M optic al w avele ngt hs i n b oth ring a nd p oin t- to -poin t config urations. All components are col o r-coded by wavelength (Table 1 on page 7). The optical routing system also includes the following:

• Optical multiplexer-demultiplexer (CWDM OMUX)

• Optical add/drop multiplexer (CWDM OADM) For more informat ion about the optical routing system, and

connecting CWDM GBICs t o CW DM OM UX s and CWDM OADMs, see Installation and Networking Guidelines for Optical Routing, part num ber 212257- A .
