DW4200 series Reconfigurable OADM System Multi-reach DWDM platform Higher bandwidth clients such as Gigabit Ethernet are becoming one of general demands. Service providers have to flexibly and rapidly deliver high quality and high bandwidth services anywhere and anytime. The SpectralWave DW4200 series provides remotely controllable optical add, drop or passthrough functions at any nodes and any wavelengths on a 80 channel DWDM platform, also provides adjustable passive optical add, drop or pass-through functions. The SpectralWave DW4200 series offers high bandwidth, flexible and economical optical network. Multi-Service Optical networks should flexibly support various interface capability without surplus facilities for rapid and diverse service demands. The SpectralWave DW4200 series provides a Bitrate Free transponder (3R) for wide range of optical clients from 100Mbit/s to 2.7Gbit/s including Gigabit Ethernet and Fiber Channel. In addition, a Multi-rate SDH/SONET transponder is provided for STM-1/OC-3, STM-4/OC-12 and STM16/OC-48 with B1 performance monitoring of SDH/SONET frame. For data centric demands, 10Gig-E LAN-PHY and 9-channel Gigabit Ethernet transponders are provided. Scalable and Easy System Design Different optical path may have different loss budget. When new paths/nodes are added, the system design is very complicated due to uneven spectral power level. The SpectralWave DW4200 series supports predominant automatic optical power control and gain flatness control functions. These functions enable easy λ expansion and network configuration upgrade without manual gain adjustment and complicated system re-design work. Full Band Tunable Transponders 80 channel full band tunable in C-band or L-band for spare cost saving and rapid service establishment In-service Upgrade Optical networks are growing according to broadband demands. Terminal nodes or in-line amplifier nodes may be upgraded to intermediate add/drop nodes for new demands. The SpectralWave DW4200 series enables economical in-service upgrade from DWDM terminals or in-line amplifiers to ROADM configurations with minimum investment.
