Installation and Networking Guidelines for Optical Routing
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:
This book contains the following topics:
“Describing the optical routing system” on page 17
“Calculating transmission distance” on page 27
“Installing the shelf, OADM, and OMUX” on page 35

Component Function
CWDM Gigabit interface
converters (GBICs)
Convert signals in a switch to laser light for connection to a
fiber optic network.
Passive optical
multiplexing devices
Combine laser light signals received from GBICs onto a
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.
