In Backbone Networks
In backbone networks, efficient use of existing fiber is critical to satisfying bandwidth demands. The Alcatel-Lucent 1675 LambdaUnite MSS efficiently aggregates and grooms traffic to help maximize bandwidth utilization and lower per-bit costs. The optional, fully transparent OC-48/STM-16 inter- face card can help carriers to cost- effectively address wavelength service delivery using the existing SONET/ SDH network infrastructure.
Figure 1 shows two complete Alcatel-Lucent 1675 LambdaUnite MSSs in one rack, with a capacity of 640G.
With DWDM Systems and
Transoceanic Applications
When the Alcatel-Lucent 1675 LambdaUnite MSS is deployed with an Alcatel-Lucent dense WDM (DWDM) system, you can achieve significant equipment savings by using express optics because expen- sive optical transport units (OTUs) on the DWDM equipment are eliminated.
The Alcatel-Lucent 1675 LambdaUnite MSS is well suited for transoceanic applications. The transoceanic protocol mechanism supported by the system helps to effectively protect groomed and consolidated traffic for your valuable undersea fiber route.
