| Introduction
to DWDM
Duration: 2 hours
THE MARKET
- Dense wavelength
division multiplexing (DWDM) and differentiation
from both time division multi-plexing and wave
division multiplexing
- Principal bandwidth
drivers creating the need for DWDM in the network
- DWDM cost and
performance vs. deployment of new fiber
FIBER OPTIC TECHNOLOGY
OVERVIEW
- Fiber optic systems
concentration on the 1310 and 1550 nanometer
wavelengths
- Dispersion shifted
and dispersion flattened fiber
- Lasers vs. fiber
amplifiers with regard to spectral bandwidth
- Electro-optical
cross-connect construction
- Tuning lasers to a
specific wavelength
- Key components and
functions of Bragg grating filters
DWDM TECHNOLOGY
OVERVIEW
- DWDM system elements
- Feasibility of
bidirectional DWDM systems
- Optical ADM
structure and function
- Standards in
building interoperable DWDM systems
- Effects that limit
DWDM transmission distances and speeds, and
procedures that can minimize their impact
- Alternative protocol
"stacks" that reside "on top of
" DWDM
ARCHITECTURES
- Wavelength grooming
in assuring the penetration of DWDM into the network
- DWDM configurations
in long-haul and local network environments
