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 49 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! 50 Service Aware Networking Technologies LambdaDriver RAMAN amplifiers “Long” double slot size fits in LD1600 and LD400L chassis 3 types available : – EM1600-OAR10 - 10db Raman Amplifier – EM1600-OAR12 - 12db Raman Amplifier – EM1600-OAR15 - 15db Raman Amplifier Bundle kits are defined appropriately : – LDROAx includes LD400L/2AC + EM800-MNGD+ EM1600-OARx Where x = Gain (10/12/15) 51 Service Aware Networking Technologies Optical transport solutions 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 Service Aware Networking Technologies Combating Chromatic Dispersion Use DSF and NZDSF fibers – (G.653 & G.655) Transmitters with narrow spectral width Dispersion Compensating Components Service Aware Networking Technologies Dispersion in different fibers 56 Type Dispersion @1550 Vintages SMF 17 ps/nm/km 1980- E-LEAF 4 ps/nm/km 1996- TrueWave RS 4.5 ps/nm/km 1996- TrueWave Classic 2 ps/nm/km 1992-1996 DSF 0 ps/nm/km 1990-1992 SMF-LS -1 ps/nm/km 1992-1995 Service Aware Networking Technologies 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 57 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. 59 Service Aware Networking Technologies 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!

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! 63 Service Aware Networking Technologies 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). 64 Service Aware Networking Technologies LambdaDriver® TDM Sub-Rate Transponders Running more services over the same wavelength 65 Service Aware Networking Technologies 2 x GE/FC Multiplexer module 2 x GE or 2 x FC 1Gbps ports are TDM multiplexed into SFP WDM port 2.5Gbps uplink for maximum utilization of the available wavelengths.

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! 103 Service Aware Networking Technologies And what is the first step in the installation?
