Wave Division Multiplexing (WDM) – is the solution for every fiber bottleneck!

WDM is a method of transmitting data from different sources over the same fiber optic link at the same time whereby each data channel is carried on its own unique wavelength.

What differentiate MRV WDM proposal

The same platform supports both CWDM and DWDM technologies and

even can support both in the same network

Support for up to 18 CWDM channels thus lowering the cost compared

to DWDM alternative.

In-field 10Gbps upgrade for existing WDM networks

Using Sub-Rate TDM modules for more efficient use of WDM channels

Single fiber bi-directional transmission of up to 80 channels!

Using SFP transceivers provides high flexibility and maintenance

inventory savings

MRV’s Vision of theEnd-to-end Transport Network

• Mix of CWDM and DWDM segment-by-segment. • CWDM segments up to 120 km unamplified at GigE (80 km at 2.5G).• DWDM reach of more than 900km (10G) with no regeneration: only amps and

DCM required.• Mix of 10G, 2.5G, 1G, 100Mbps, 2Mbps services on the same fibre.• Sophisticated, integrated, managed amps & dispersion compensation.• Comprehensive, central/remote network and element management.

When building a Ring or Linear ADM topology only part of the wavelengths need to be dropped/added at every node.

OADM’s – “pass through” without substantial attenuation all the channels that are not dropped.

MUXMUX DeMUX

DeMUX


Uses RAMAN effect in fibers to provide Distributed Amplification (in contrary to EDFA).

The optical signal is amplified along the fiber and thus arrives at the end of the link at higher power and better OSNR – improving system performance at long distances.

The gain is dependant on fiber type (10db minimum for G652 and higher for G655).

RAMAN amplifier

Forward pumping Backward pumping


The fact that optical signal is amplified along the fiber, results in higher signal (and OSNR) at the end of the link thus improving system performance.

Maximum distance with EDFA Booster is about 160km for one 10GE service. With Raman addition, the distance can be increased to about 220km!

RAMAN amplifiers consume 100 times more power per dB of Gain than EDFA

RAMAN gain is dependant on fiber type

RAMAN versus EDFA

Conclusions from EDFA NF calculation: Move the Gain Before Loss

And this is exactly what RAMAN does!

Dispersion Compensators

Service Aware Networking Technologies

• Polarization Mode Dispersion (PMD) Single-mode fiber supports two polarization

states

Fast and slow axes have different group velocities

Causes spreading of the light pulse

• Chromatic Dispersion Different wavelengths travel at different speeds

Causes spreading of the light pulse

Types of Dispersion


Chromatic Dispersion

Affects single channel and DWDM systemsA pulse spreads as it travels down the fiber Inter-symbol Interference (ISI) leads to

performance impairmentsDegradation depends on:

–laser used (spectral width)–bit-rate (temporal pulse separation)–Different SM types

Interference

How Far Can I Go Without Dispersion Compensation?

Distance (Km) =Specification of Transponder (ps/nm)

Coefficient of Dispersion of Fiber (ps/nm*km)

A laser signal with dispersion tolerance of 5400 ps/nm

is sent across a standard SMF fiber which has a Coefficient of Dispersion of 17 ps/nm*km.

It will reach 300 Km at maximum bandwidth.

Lower Speeds Minimize Dispersion Impact


Dispersion Compensating Fiber

Dispersion Compensating Fiber: By joining fibers with CD of opposite signs

(polarity) and suitable lengths an average dispersion close to zero can be obtained; the compensating fiber can be several kilometers and the reel can be inserted at any point in the link, at the receiver or at the transmitter

Disadvantages :

–High loss (10db for 80km)

–Big size

–High cost


LambdaDriver DCMs

•The module is transponder size and fits into all LD chassis•The main application is extending the distance for 10Gbps protocols.•Pre-compensation and Post – compensation (less effective) are possible.•Fixed Dispersion compensation of 1300ps/nm (with small tilt over C-band) – usually placed every 70-80km together with InLine amplifiers.•Typical loss is 5db, but using Mid-Stage amplifiers eliminates this loss.•NEW! Remotely tunable DCM +/-1700ps/nm – NEW! Remotely tunable DCM +/-1700ps/nm – release in October.release in October.


Advantages of MRV’s DCM versus DCF

Low insertion loss – save Optical Amplifiers Small size – fits in the same chassis as OAs Remotely Tunable Dispersion Compensation!

– Allows fine dispersion tuning at the end of line – extending the transmission distance without OEOs.

– One unit for all distances – saving spares and OPEX

– Provides both Negative and Positive compensation – good for any fiber installed!

Dispersion Accumulation versus wavelength

•Fiber dispersion is not equal along C-band and therefore after a distance, despite dispersion compensation, different channels have different accumulated dispersion•At some point placing fixed DCM/DCF will not compensate all channels and some channels will be overcompensated or undercompensated!


The perfect solution – End Of Line Tuning!

MRV’s 10G transponders (TM-GM8D20T) are

Wavelength and Dispersion Tunable! Transponder based per-channel dispersion

tuning at the receiver (-1700 to 3500ps/nm), allows long distance transmission over the whole C-band without the need for per-channel DCM/DCF

Full C-band wavelength tuning provides the network flexibility and saves CAPEX (spares).

ROADM basic functions

ROADM basic functions– Add, Drop, Block or Attenuate any wavelength in any node – controlled by

remote management– Power monitoring and equalization of any wavelength– In Multi-Degree units every port can be configured for single wavelength or

any size band of waves.

The result is: Fully flexible transport networks

Hitless networks upgrades and changes

Full power monitoring and control

SAVE on spares

SAVE on OPEX

Fast time to market

Fixed OADM ROADM ROADM AdvantagePredefined number of channels in each node

Any number and type of waves can be selected in any node

Network configuration Highest flexibility. Future upgrades do not disconnect the fiber. OPEX savings.

Non equal channels power levels at node output.

Per channel power level equalization and monitoring

Easy network design. Efficient use of Optical Amplifiers without the need for fixed attenuators

Every node is unique waves configuration

All nodes have the same equipment

Savings on spares. Easy network design.

Upgrades requires additional power compensation

All EDFAs are deployed at the initial stage

In-service network upgrades

Preserves all functions of regular transponder Tunable wavelength over the whole C-band – highest network

and maintenance stock flexibility High power output – minimum 9dbm – saves cost of Booster

F/O SFP


New LD1600L chassis-Q2/2007

New high density aggregators and FEC transponders require “long” slot space

Existing LD1600 supports only 6 “long” slots

LD1600L is similar to LD1600, but with 10 “long” slots and 8 “short” slots, thus the optimal mix of different slot sizes


MRV MultiDegree ROADM

1x9 WSS switch – availability Q2/2007

– 9 Add/Drop ports

– Fully tunable drop ports (single wavelength or multiplex section)

– Enabler for ring to ring or mesh network designs


So what to do when you meet WDM opportunity?

Selling WDM is usually a teamwork:

– Sales manager/partner : should provide as much information as

possible regarding topology, infrastructure and requirements

– Network design may involve not only the local team, but also may

require MRV project and product managers.

– MRV is a solution provider rather than box mover!


And what is the first step in the installation?

Please read the User Guide!
