What is the minimum number of chassis to deploy an 8x200G (2x100GE) WDM system with DC908?

The correct answer is1. TheOptiXtrans DC908is designed to support high-density configurations,

allowing an8x200G (2x100GE)WDM system to be deployed using justone chassis.

Here’s a breakdown of how this is achieved:

High Integration:The DC908 integrates multiple components, such as optical modules, amplifiers,

and control units, into a single compact2U chassis. This eliminates the need for additional hardware

or external devices.

Scalability:The DC908 supports up to8 wavelengths per fiber pair, each operating at200G. This means

that all 8x200G channels can be accommodated within a single device.

Service Aggregation:Each 200G wavelength can carry multiple 100GE services, enablingefficient

aggregation of traffic. For example, two 100GE services can be mapped onto a single 200G

wavelength.

Space Efficiency:By consolidating everything into one chassis, the DC908 minimizes rack space

requirements, making it ideal for data centers and edge locations where space is limited.

Other options:

2, 3, or 4 chassis:These would only be necessary for extremely large-scale deployments or if

additional redundancy were required. However, for an 8x200G system, a single chassis is sufficient.

This compact design highlights the DC908’s efficiency and cost-effectiveness for modern optical

networks.
