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 .

Handling, safety, and environmental guidelines

Before installing a CWDM GBIC, read the following handling, safety, and environ m ental guidelines:

• CWDM GBI Cs ar e static sensitive. To prevent dam a ge from electrostatic discharge (ESD), follow your normal board and component handling procedures.

• CWDM GBICs are dust sensit ive. When you store a CWDM GBIC, or when you disconnect it from a fiber opt ic cable, always keep the dust cover over the CWDM GBIC’s optical bores.

• To clean contaminants from the optical bores of a CWDM GBIC, usean alco hol swa b or equiv al ent to cl ea n the f er ru les of the optica l conne ct or. This also hel ps to pr event damag e t o the ferrules during handling.

• Dispose of this product according to all nati onal laws and regulations.

Warning: Fiber optic equip ment c an emit la ser or infr ared

light that can injure your eyes. Never look into an optica l fiber or c onnect or por t. A lways as su me t hat fib er optic cables are connected to a light source.

Installing a CWDM GBIC

Use the following procedure to install a CWDM GBIC in a switching module. This procedure requires an alcohol swab for cleaning the ferrules of the optical connector to pre v ent damage during ha ndling and installation.

To install a CWDM GBIC in the sw itching module:

1 Remove the CWDM GBIC from its protective packaging. 2 Verify that the CWDM GBIC is the correct wavelength for

your ne twork configur at i o n (Table 1 on page 7).

3 Remove the dus t cover from the CWDM GBIC’s optical

bores.

4 To prevent damage during handling, clean the ferrules of the

optical connector with an alcohol swab.

5 Grasp t he CWDM G B IC between your thumb and for efinger. 6 Insert the CWDM GBIC into the slot on the front panel of the

Giga bi t E t hernet sw i t c hi ng modu le (Figure 3). A clicking sound indicates it is properly seated.

Note: CWDM GBICs are keyed to prevent imp roper

insertion. If the CWDM GBIC resists pressure, do not force it. Remove it, turn it over , and reinsert it .

The CWDM GBIC is installed. For instructions about connecting the CWDM GBIC to a

multiplexer, see Installa tion and Networking Guidelines for Optical Routing, part number 212257- A .

For instructions about monitoring communica tion between the CWDM G BIC an d th e swi tch, se e th e us er’ s gu id e fo r the switch.

Removing a CWDM GBIC

Use the following procedure to remove a CWDM GBIC. When storing a CWDM GBIC, place a dust cove r over the fiber optic bores

Note: When disposing of a CWDM GBIC, comply with

all nati onal laws and regulat ions

To remove a CWDM GBIC from the switching module:

1 Disconnect the fiber cable from the CWDM G B IC connector. 2 Grasp th e ex tractio n ta b s (Figure 1) located on either side of

the CWDM GBIC between your thumb and forefinger.

3 Slide th e CWDM GBIC out of the Gigabit Etherne t m odule

slot.

4 If the CWDM GB IC does not slide easily from the module

slot, use a gentle side-to-side rocking motion while firmly pulli ng the CWDM GBIC from the slot.

Note: A minimum attenuation of 5 dB must be present

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

• testing the 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 b udget of 24 dB and assuming fib er loss of .25 dB/km, up to 96 km reach is supported with no intermediate CWDM OADM or CWDM OMUX.
