3. Background Overview
The increasing demand for bandwidth along with the fact that it is relatively very expensive in many cases to lay new fiber implies that we must find ways to increase the capacity on existing fiber.
In metro environments, operators and city carriers have mostly built networks based on SONET/SDH technology, which are already operating at full capacities.
Moreover there are a variety of diverse formats that must be covered in metro environment including Storage Area Network (SAN), Gigabit Ethernet, 10- Gigabit Ethernet which require separate networks as SONET/SDH was not originally designed to handle them
Dense Wavelength Division Multiplexing (DWDM) is a scalable long term solution which addresses all these aspects along with non scraping of existing hardware

4. Technical Terms
SONET/SDH Synchronous Optical Network /Synchronous Digital Hierarchy
STM -1/OC Synchronous Transport Module / Optical Carrier B/W= Mbps. OC defines transmission by optical devices in SONET Specs
STM -4/OC B/W= 622 Mbps.
STM -16/OC B/W= 2.5 Gbps.
DWDM Dense Wavelength Division Multiplexing
CWDM Coarse Wavelength Division Multiplexing
GbE 802.3z Gigabit Ethernet over optical fiber and shielded twisted pair

5. Introduction to DWDM
Data is transmitted simultaneously at multiple carrier wavelengths over the same fiber (concept similar to frequency division multiplexing in RF)
Provides a way to increase the transmission capacity using multiple channels at different wavelengths
Extremely efficient in terms of capacity, scalability, and transparency
Currently being used for international and national long-haul (LH) networks primarily due to very high deployment and operational costs
High cost wide band and high power optical amplifiers are needed to offset the optical losses generated in conventional DWDM solutions even if extended to shorter Metro environments
Lumentis has developed a low cost scalable DWDM solution for deployment in Metro networks

6. Why Lumentis
Lumentis solution has a higher tolerance for optical losses
Provides a very high capacity without the need for optical amplifiers, therefore can be deployed where conventional DWDM solutions are not feasible
One single platform to handle both SONET/SDH and WDM (CWDM & DWDM) traffic
Multi rate traffic from 100 Mbps to 10 Gbps.
Any distance from Km in mix, pt. to pt, bus or ring topologies in metro networks
20 wavelengths channels in C Band, 40 wavelengths in L Band
Scalable, protocol transparent and expand as you grow
No scalability dead ends

7. Advantages of using No Optical Amplifiers in Lumentis Solution
Low initial investment
Easier Wavelength Management
More reliable network
Lower life cycle costs
Minimized site cost
20 wavelengths channels in C Band, 40 wavelengths in L Band
More no of Add /drop nodes
Each Fiber in the Fiber Pair can be used separately
