Data Center Interconnect

Data Center Interconnect

The MPBC DCI optical amplification subsystem is a complete DWDM line system for data center interconnect direct detect applications. It provides all of the optical grooming necessary for transmission of up to 80 direct detect carriers, covering the range of 5 km to 100 km SMF while maintaining the simplicity of zero-touch provisioning. The unit has been optimized for ease of data center operations based on the contributions of world-leading data center operators and successfully tested with Inphi’s ColorZTM PAM4 QSFP modules.

Features

Application

DCI-SR Series

The DCI-SR unit is composed of a multiplexer / demultiplexer, optical amplifiers, dispersion compensators and an optical supervisory channel.

DCI-LR Series

In addition to the similar components used in DCI-SR, DCI-LR unit has the addition of a Raman counter pump which provide additional gain over the entire C-band.

Interoperability Test Results

MPB and Inphi have conducted successful interoperability tests with fully-loaded 40 Inphi ColorZTM PAM4 100 G QSFP28 modules2 at 125 km of Corning SMF-28 fiber. Long term Post-FEC error free transmission was successfully demonstrated:
