DWDM & CWDM
Fundamentals, Technology, New Test Needs, MARKET and TRENDS
Course Summary:
WDM technology (Wavelength Division Multiplexing) has revolutionized the telecommunications market in the whole world by offering a phenomenal cost-effective increase in the fiber transmission capacity. It is the best alternative to satisfy the growing demand for bandwidth current seen in worldwide telecom networks
DWDM (Dense WDM) became commercial in 1995 while CWDM (Coarse WDM) emerged after 2000, stimulated by the telecom crisis
CWDM brings simpler technological concepts as compared to DWDM, cutting down prices, but fits just the lower transmission capacity markets, such as the metro and enterprise networks. More than 90% of the long distance fiber links in the US and Europe already makes use of DWDM technology.
Applications of C&D WDM in metropolitan, enterprise and cable television networks are also growing. The worldwide market of WDM equipments was about US$ 8,9 billion in 2000, with an annual growth (CAGR) of 73%. In 2001, annual growth rate was of 43%. Between 2001 and 2004, the market went through a deep crisis. Its recovering in the last years on its way.

Chromatic Dispersion and Compensation Dispersion
in Long Distance High Capacity Optical Transmission Systems
Duration:
4 or 8 Hours
Instructor:
Dr. Sérgio Barcelos
Description:
The growth of transmitted data and the appearance of new telecommunication services has been demanding ever higher transmission capacity in fiber optic links. Fiber chromatic dispersion and loss are the key obstacles to obtaining this. The emergence of erbium-doped fiber amplifiers operating in the 1550 nm region has eliminated fiber loss as a fundamental limit to achievable transmission distance and made it possible to transmit optical data over thousands of kilometers of single-mode fibers without electronic regeneration.
However, the lack of intermediate regenerative repeaters causes the chromatic dispersion to build up along the entire system length, rather than just in between repeaters. The use of dispersion-shifted (DS) fiber with zero dispersion wavelength near 1550 nm is one obvious solution. However, this is not cost effective as, first, DS fiber exhibits higher loss, second, it is more expensive and, third, because the embedded fiber plant throughout the world largely contains standard single-mode fiber.
Consequently, alternative means for compensating for the chromatic dispersion must be sought if standard fiber is to remain in use for building the future high-speed amplified systems.
Several strategies for dispersion compensation (DC) have been explored and can be categorized into three main areas: pre-distortion, post-detection and all-optical techniques. Pre-chirping of laser pulses and frequency-to-amplitude conversion are examples of pre-distortion schemes. Post-detection makes use of frequency-dependent delay lines in conjunction with coherent detection or special signal processing at the receiver if direct detection is used.
All-optical techniques include the use of dispersion-compensating fibers, the highly dispersive higher-order mode in a two-mode fiber, optical phase-conjugation (or midpoint spectral inversion), and optical filters (such as birefringent crystals, Gires-Tournois interferometer, cascaded Mach-Zehnder interferometers, fiber grating-assisted intermodal coupling, periodic fiber gratings, and chirped fiber Bragg gratings).
By far, R&D activities on dispersion-compensated optical transmission systems have been mostly concentrated on pre-chirping, dispersion-compensating fibers and chirped fiber Bragg gratings, which is probably because of their simplicity and practicality.
In this course, we initially describe the principles of Chromatic Dispersion and the limitations it imposes in the transmission capacity of analog and digital optical systems. Next, we discuss the existing fiber dispersion measurement techniques and present a survey of commercially available dispersion measurement instruments.
Then, we discuss the use of dispersion shifted fibers (DSF and NZD) and present the main techniques proposed so far for dispersion compensation in monocanal and WDM optical fiber links. "Pre-Chirping", "Spectral Inversion", "Dispersion Compensating Fiber" and "Chirped Fiber Grating" techniques are discussed in details. The use of Chirped Fiber Gratings is specially highlighted for being the most practical and economic solution.
Its operation principles, fabrication techniques, theoretical modeling, applications to telecommunications, etc, are introduced. Finally, chromatic dispersion mapping and management along the fiber link are discussed.
Polarization Mode Dispersion (PMD)
in Optical Communications
Description:
Polarization Mode Dispersion, PMD, is a parameter of great importance in modern optical communications. It imposes limitations on both analog (CATV) and digital (telecommunication) optical systems. System designers need to understand well the subject of PMD for them to specify fibers and other components. On the other hand, fiber and cable manufacturers must develop products that satisfy the increasingly demanding specifications. Also, installation techniques have to be reviewed to guarantee that the PMD stays below acceptable levels. On the other hand, international bodies such as ITU, TIA, IEC and EU-COST have been conducting several studies, intending to create technical recommendations related to PMD.
PMD arises from the fact that even in current fibers, which have excellent geometry and little internal stress, there exists a small level of birefringence. Birefringence causes pulse spreading due to the slight difference between the propagation velocities of the two orthogonal polarization states that constitute the light signal. Due to fiber movements, temperature variations and other environmental variations, these two polarization states couples strongly. This makes PMD to be wavelength dependent and strongly affected by the environment. Thus, PMD varies randomly and is best characterized through statistical measurements.
PMD imposes a limit in the information transmission capacity of long distance optical telecommunication systems. For instance, a 400 km 10 Gbit/s standard fiber link demands fiber with PMD <0.5 ps km-1/2. In the case of DS (Dispersion Shifted) fibers or higher transmission rates, a PMD < 0.1 ps km-1/2 should be specified. Analog optical communications (CATV) is also affected by PMD, which introduces distortions and adds noise to the signal. Several newly installed CATV systems have required rework due to unfortunate combinations of these parameters.
A key element in keeping PMD under control is its proper measurement. This allows quality control and introduction of improvements in the fiber and fiber cable manufacturing processes. It allows also to evaluate installed links and to investigate special cares needed during the link design and installation techniques. Several methods have been proposed to measure PMD. Unfortunately, there are no standardized methods or agreement on which are best qualified for laboratory or field use. This is very much due to the statistical nature of PMD, which makes it difficult of being clearly measured.
In this course, we explore all aspects related to PMD. Initially, we describe its origins and statistical characteristics associated to its dependence with geometric and environment variations of the fiber. Next, we describe the influence of the link length and the effects of PMD in analog optical systems (CATV) and digital telecommunication optical systems. The interaction of PMD with polarization dependent loss and gain (PDL and PDG) of the system components are discussed as well. The different existing measuring methods, their limitations and accuracies are presented and compared.
Standardization studies by the ITU, TIA, IEC and EU-COST on measuring techniques and recommended PMD values are also shown. A detailed survey of the measuring techniques best recommended for laboratory (fiber manufacturing) and field (fiber installation) use is presented, followed by discussions about and the commercially available instruments for such purpose. Measurement procedures and special cares during system design are discussed. The influence of the fiber and fiber cable manufacturing processes and of the installation techniques on the PMD levels are shown. PMD values for different fibers and optical devices are presented, with special emphasis for the comparison between conventional fibers and dispersion shifted fibers.
This course is intended for telecommunication and CATV optical system designers, for engineers and technicians involved in the manufacturing process of fibers and fiber cables, and for fiber cable installation technicians.

Fiber Bragg Grattings
for Applications to Optical Communications and Sensors
Course Summary:
A fiber Bragg grating is a short section of optical fiber in which the core refractive index has a periodic modulation. They are produced by exposing a photosensitive fiber to a periodic pattern of ultraviolet (UV) light. Their fundamental property is to reflect light over a narrow spectral range centered at a resonant wavelength known as the Bragg wavelength, lB = 2× L× neff, where L is the period of the index modulation (or grating pitch) and neff is the effective refractive index of the fiber mode. Their reflection spectra have shape similar to the "sinc2" function and are characterized by the grating FWHM (full-width at half-maximum) bandwidth, B3dB, and peak reflectivity, Ro, which are function of the grating length, the amplitude of its index modulation and the Bragg wavelength.
Fiber Bragg Gratings can be used to reflect, filter or disperse light within an optical fiber. Their ease of fabrication and use combined with their unique properties and great advantages make them ideal for a great number of applications in telecommunications, fiber sensors and lasers. In this tutorial course, we explore all aspects related to this revolutionizing device. Its principles, fabrication techniques, types, apodization, theory and modelling, recent technological advances and applications to fiber amplifiers, lasers, WDM devices, filters, taps, dispersion compensators and sensors are covered.
