Preface

Nortel Networks* optical routing system supports high-speed data communications in metropolitan area networks (MANs) by:

•Connecting Gigabit Ethernet ports with fiber optic networks.

•Combining multiple wavelengths on a single fiber to expand available bandwidth.

The system components include:

Component	Function
CWDM Gigabit interface	Convert signals in a switch to laser light for connection to a
converters (GBICs)	fiber optic network.
Passive optical	Combine laser light signals received from GBICs onto a
multiplexing devices	single fiber for transport to the destination. Separates the
	wavelengths at the destination and routes them onto
	different fibers which terminate on separate GBICs.
Passive optical shelf	Houses the multiplexers.
