Q&A

What is the reach of the Cisco QSFP-40G-SR4-S?

The Cisco QSFP-40G-SR4-S supports 100 m on OM3 / 150 m on OM4 over Multimode fiber (MMF), using MPO-12 (MTP) connectors. Confirm the fiber grade and the optical budget of the link before ordering.

What connector does the Cisco QSFP-40G-SR4-S use?

The Cisco QSFP-40G-SR4-S uses MPO-12 (MTP). MPO/MTP cabling is required — duplex LC patch cords will not fit.

How does the Cisco QSFP-40G-SR4-S compare with the Cisco QSFP-40G-SR4?

The QSFP-40G-SR4-S reaches 100 m on OM3 / 150 m on OM4 over Multimode fiber (MMF), while the QSFP-40G-SR4 reaches 100 m on OM3 / 150 m on OM4 over Multimode fiber (MMF). Pick the shortest reach that covers the link distance — going longer than needed costs more and adds optical budget margin you will not use.
