Metro WDM Systems
Two NEC product families are available for metro WDM systems the TM Series and MW Series. These carrier-grade optical networking solutions enable transparent transport of any service at 100Mbit/s to 10Gbit/s for metropolitan and regional applications.
Features
- Mobile transmission networks
- City carrier networks
- High-end enterprise networks
- Storage networks
- Triple-play networks
- Long-haul networks
TM Series
TM-3000 / TM-301 / TM-101
The TM-3000 Series platform is a carrier-grade optical networking solution allowing transparent transport of any service at 100Mbit/s to 10Gbit/s for metropolitan, regional and long haul applications.
This solution supports any type of network within the metro WDM environment, including:
- Mobile transmission networks
- City carrier networks
- High-end enterprise networks
- Storage networks
- Triple-play networks
- Long-haul networks
The cornerstone of the TM Series is a unique system architecture that includes CWDM, DWDM and SDH/SONET transmission solutions within a single system.
Features
- Three types of chassis: High-capacity central office, medium-capacity central office and single ?CPE
- Two types of passive unit: CWDM and DWDM allow modular expansion for capacity growth
- Tunable transponders/muxponders: Minimal spare part costs
- Pluggable transponders/muxponders: A flexible combination of CWDM, DWDM and reconfigurable HW solutions
Benefits
- Modular, flexible and incrementally expandable from access to medium-haul
- Cost-effective solutions via seamless integration of DWDM and CWDM
- Layers 1 and 2 combine in a single platform
- Low power consumption (< 700W ) and small footprint
- Embedded management channels reduce costs and simplify DCN setup
- Carrier-class FCAPS
- Multi-service support (Ethernet, SAN, SDH/SONET, OTN, DVB-ASI, DVB-SDI)
- Manageable via embedded node manager (ENM) or Transmode network manager (TNM)
- The flexibility of stand-alone, combined single-fiber or fiber-pair configuration
