The 40GBASE-SR4 QSFP+ module remains the most widely deployed 40G optic in data centers, carrying four 10G lanes over an MPO-12 multimode trunk for up to 150 meters on OM4.
The module complies with the QSFP+ MSA and IEEE 802.3ba 40GBASE-SR4 and supports breakout to four 10GBASE-SR links when paired with MPO to LC harness cables, protecting investment in mixed-speed rows.
