DCI Short Reach & Long Reach

The MPB’s DCI Optical Line System (OLS) is a complete DWDM line system for data center interconnect applications. It provides all of the optical grooming necessary for transmission of up to 40 DWDM PAM4 channels, 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



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:
