Rationale Behind The Need For WDM


Massive Traffic Growth The Need For Optical Networking

Constant traffic growth and Customer demands challenges network architecture

More capacity

More flexibility

Delivery on request

Impossible to predict

location level and timing

Evolution from electrical transmission to SDH/Sonet to WDM

Traffic growth outstrips dropping equipment cost


WDM Principles


TDM -> WDM

Example SDH:

Multiplexing of 4x STM-16 (2.5G) onto 1x STM-64 (10G)

TDM: Time Division Multiplexing

WDM: Wavelength Division Multiplexing Wavelength Division Multiplexing Many wavelengths multiplexed on the same fiber

Types of WDM:

CWDM – Coarse WDM

DWDM – Dense WDM


What is WDM? Comparison to a freeway

What is WDM?

•  Wavelength Division Multiplexing (WDM) combines a number of data channels onto a single fiber pair.

•  Each channel is transmitted on a separate color. •  The channels are combined using optical filters.

O/E/O Conversion

3R Regeneration

•  Re-amplification

•  Re-shaping

•  Re-timing

Mapping or Framing Examples:

•  G.709 Framing

•  GFP Mapping

•  TDM Multiplexing

•  OTN Multiplexing

n Client Interface

•  „grey interface“

•  Input e.g. 850nm, 1310nm or 1550nm

•  Interface client data type specific e.g. SDH, FC, Eth

Line Interface

•  „colored interface“

•  G.694.1 for DWDM

•  G.694.2 for CWDM

Convert "grey light" to "colored light"


Optical Amplification

Attenuation of transmitted light in fibers

Compensation by optical amplifiers

•  Spontaneous emission or noise by amplifiers

•  Decreasing optical signal to noise ratio (OSNR) at every amplifier site

Certain OSNR level required by receiver to correctly detect signal

•  Limitation of total transmission distance

OSNR requirements vary for different bit rates and therefore this distance depends on data rate per wavelength as well.


OADM Principle

OADM: Optical Add/Drop Multiplexer •  Provides Mid-Span access to (any) wavelengths

•  Avoids expensive Back-to-Back coupling of transponders

•  Fixed filters (FOADM) or flexible filters/switches (ROADM)


Optical Layer Versatility

Flexibly configurable network resources for automated provisioning.

§  Reduced footprint

§  Reduced power consumption

Traditional core networks §  Management silos enforce

operational separation, slowing reaction to traffic changes

§  Layer interconnects drive interface counts

Operational simplification §  Integrated management solution

ROADM


ROADM Benefit

•  Static WDM engineering rules and scalability can be quite complex (every node an OADM):

•  Bandwidth and wavelength pre-allocation •  Margin allocation for fixed filter structure •  Insufficient power management •  Network extension requires OEO regeneration

•  SDH/Sonet networks are simple to plan: •  Access to entire bandwidth at every ADM •  Simple engineering rules (single hop only) •  Easy addition of new network elements

•  Reconfigurable optical layer enables: •  On demand bandwidth planning •  Extended transparent reach due to power

management per WDM channel •  Hitless scalability even in node degrees

ROADM enables scalable engineering rules

Operational enabled by: Control Plane and Service Manager

Separated Rings !  Regeneration is a must

!  Pre-allocated bandwidth & channel plan

Metro/Regio Core - Access Separation !  Transponder rich

!  High cost in case of increasing bandwidth demand

ROADM Static photonic layer


ROADM Dynamic reconfigurable photonic layer

Interconnected Rings !  4+ Degree Interconnection

!  Any wavelength to any ring to any port

Metro/Regio Core - Access Separation !  3 and 4+ Degree Interconnection

!  Fully flexible and scalable

!  Optical pass-through from access to metro/regional core


ROADM Key technology

WDM ROADM components are based on two basic elements:

•  Dispersive element (grating, prism …) to separate different wavelength in space

•  Switching element to redirect separated wavelengths into different paths / ports
