Metro

Metro networks link providers’ central offices, data centers, cell towers, large businesses in metropolitan areas. They consist of Metro Access, Regional and Core networks spanning up from 80 km to 1,200 km . These networks operate from dense, power-constrained service environments, yet must deliver ever-more bandwidth to meet customer needs.

Transmission Equipment Requirements

Metro network transmission equipment must:

  • Support a large number of ROADMS in metro networks.
  • Support older fiber which has higher loss and whose other characteristics may or may not be known.
  • Have the ability to selectively introduce 100Gbit service alongside existing 10G and 40G Metro services without requiring a forklift upgrade.
  • Meet tight power requirements that operate within the power and cooling capacity of metro network service facilities.
  • Support higher port density and small footprint to meet the needs of Metro.
  • Support client /line side universal slots and pluggability for various metro transport/switching platforms .
  • Support standardized data rate and modulation formats to enable interoperability.
  • Work with low latency to support time-critical financial and banking applications.

Read how our AC-100-CFP–the first coherent 100G CFP module designed specifically for metro networks–meets these needs. It is the lowest power 100G coherent module in the market, at a price that makes 100G more cost-effective than 10G in Metro networks.

Also available is our AC-400 Flex Product family with configurability to address metro applications. By changing the configuration of these modules through software configuration, customers can use these modules to support the transmission speed and distance that is best suited to their needs including metro applications.
