Introduction of Colored Interface

Introduction of Colored Interface

Definition

The colored interface feature allows a router to directly output DWDM colored optical signals to the multiplexer of a WDM device. The data link and transport layers are not isolated.

Purpose

With the rapid growth of Internet industry and traffic, revenue growth of carriers' data services lags far behind. To address the pressure caused by traffic growth, carriers are increasing infrastructure investment and O&M costs year by year. Carriers are in the dilemma where traffic increase does not bring corresponding revenue increase. Carriers hope to reduce network layers to reduce Operating Expenses (OpEx) and Capital Expenditures (CapEx).

To satisfy this need, Huawei has developed colored boards for NE40E. With colored optical modules integrated, colored boards require fewer colorless optical modules, which reduces unnecessary optical-to-electrical and electrical-to-optical conversion. The colored optical modules also simplify network layers and reduce OpEx and CapEx.

Benefits

Colored interfaces offer the following benefits to carriers:

  • Simplified network layers: Network layers are reduced by simplifying WDM devices.
  • Reduced costs: Unnecessary optical-to-electrical and electrical-to-optical conversion are reduced to save many colorless optical modules and reduce costs.
  • Saved resources: The equipment room and power consumption are saved.
  • Simplified maintenance: O&M are simplified to reduce TTM time.
  • Enhanced reliability: Routers query module information to improve network reliability.
