Smartoptics expands 100G QSFP28 transceiver family

The 100G QSFP28 transceiver remains a popular choice for intra-rack and data centre use and therefore is an important part of Smartoptics’ portfolio of compatible optical transceivers. Now Smartoptics has added four new models to its QSFP28 product range.

The SO-QSFP28-LR4-10L and SO-QSFP28-LR4-2L are direct-modulated laser (DML) diodes for 10km and 2km applications. The DML provides a cost-effective alternative to standard LR modules based on electroabsorption modulated lasers (EML), which are better suited to Ethernet-only traffic.
