Lumentum’s 100G PAM4 (53 Gbaud) directly-modulated laser (DML) is for hyperscale data center applications. This breakthrough product complements Lumentum’s existing 100G PAM4 externally modulated laser (EML) products and offers transceiver designers a lower cost alternative.
Catering to demands for intra-data center traffic and higher speed, capacity, and reliability, the 100G PAM4 DMLs are available in samples.
It joins Lumentum’s portfolio of best-in-class laser chips that enable a wide-range of MSA-compliant transceiver modules operating at multiple data rates and wavelengths. Manufactured with Lumentum’s internal wafer production capabilities, the 100G PAM4 DML leverages advanced InP technology, using a sophisticated cavity design to operate with the same high-bandwidth performance of an EML in 100G and 400G applications, but in a small, simple, and cost-effective footprint.
The latest DML can lower the cost of 400G DR4 compared with current laser alternatives. Additionally, 800G PSM8 modules can benefit from the capabilities of the new 100G PAM4 DML, which is important as data centers transition to these modules in future top-of-rack and leaf layer applications.
To sample the 100G PAM4 DML, contact a Lumentum representative at customer.service@lumentum.com.
