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.

RAMAN amplifier
 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).
Forward pumping

Backward pumping
Service Aware Networking Technologies
RAMAN versus EDFA
 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
Conclusions from EDFA NF calculation:
Move the Gain Before Loss
And this is exactly what RAMAN does!

Dispersion Compensators
52
Service Aware Networking Technologies
Types of Dispersion
• Chromatic Dispersion
Different wavelengths travel at different speeds
Causes spreading of the light pulse
• 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
Service Aware Networking Technologies
Chromatic Dispersion
Interference
Affects single channel and DWDM systems
A pulse spreads as it travels down the fiber
Inter-symbol Interference (ISI) leads to
performance impairments
Degradation depends on:
–laser used (spectral width)
–bit-rate (temporal pulse separation)
–Different SM types

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

Service Aware Networking Technologies
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
Service Aware Networking Technologies
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 – 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.

 Every 70-80km DCU (Dispersion Compensation Unit) postcompensates the accumulated dispersion.
 Usually DCU’s are located together with In-Line Optical
Amplifiers that compensate for power loss.
62
Service Aware Networking Technologies
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
– 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

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!
