17. Padtec´s Product Lines: • Passive Optical Products • Active Optical Products • xWDM System: The Metropad Platform

18. Passive Optical Products: • They are totally optic or passive and have the following characteristics below: • Low cost and plug and play use • Does not requires power supply or management • Transparent or compatible with any transmission rate and protocol • High reliability – does not need spare unit • There is not optical-electrical conversion inside • The Padtec´s passive products are listed below: • Duplex • Quadruplex • OADM – Optical Add and Drop Multiplex

19. Active Optical Products: • They basically require optical-electrical conversion inside their modules. These products are designed to assure high reliability and flexible capabilities to the optical networks. • Characteristics: • AC or DC power supply • Dry contact reles for fail management • The active optical products of Padtec are: • Multimode-singlemode converters • Optical-electrical STM-1 converters • Media converters • Transponder of optical wavelength • Transponder quadruplex • Optical protection system • Optical amplifier family

20. Metropad Platform: xWDM Systems • xWDM Systems allow the transmission of multiples • optical signals based on a couple of fibers. • CWDM: Coarse Wavelength Division Multiplexing – up to 16 optical signals • DWDM: Dense Wavelength Division Multiplexing – up to 80 optical signals • Metropad Platform: it supports both CWDM and DWDM technologies as well their common integrated management system

21. DWDM Technology • High density system uses the minimum spacement between optical channels (usually 100 GHz), is able to support up to 80 channels of 10 Gbps each into the Metropad Platform • High transmission capacity per channel (10 Gbps) • Sophisticated and high reliability components, it requires wavelength circuit controlling • Commercial transmission: C and L bands enable optical amplification • Metropolitan, Access and long haul backbones applications of all topologies

22. CWDM Technology • Its based on low-cost components and low-density WDM (up to 16 optical channels) • 20 nm of spacement between channels (1310 to 1610 nm) • Low cost and high reliability optical components • It does not requires wavelength circuit controlling • Metropolitan and Access Applications
