QSFP-100G-SR4-S Description
QSFP-100G-SR4-S is the Cisco 100G SR4 QSFP transceiver for short 100G links over MPO-12 multimode fiber.
This optic fits data center links that already use parallel multimode cabling and need a Cisco-supported 100G QSFP module. It should not be substituted with LC BiDi or single-mode optics without checking connector type, fiber plant, reach, and far-end module.
Before purchase, confirm the host platform, MPO-12 cabling, OM3/OM4/OM5 distance, and matching remote optic. Layer23-Switch can help check QSFP-100G-SR4-S price, stock, warranty support, shipping timing, and compatibility.

Application Scenarios
Select QSFP-100G-SR4-S when the cabling design uses 12-fiber MPO multimode trunks and the 100G link distance fits Cisco’s documented OM3, OM4, or OM5 reach limits.
This SKU fits refresh projects where SR4 MPO infrastructure is already in place and the buyer needs Cisco-qualified 100G optics for supported QSFP ports. Confirm the host platform, line card, software release, and remote optic before quote release.
Keep QSFP-100G-SR4-S separate from QSFP-100G-SR-S, QSFP-100G-SR1.2, and QSFP-40/100-SRBD during receiving and spares planning. The names are close, but Cisco documents different connector types, wavelength behavior, and reach profiles.

- QSFP-100G-SR4-S is the SR4 MPO option for 100G multimode links up to 100m on OM4 or OM5 cabling.
- QSFP-100G-SL4 uses the same MPO-12 connector style but is documented for shorter 20m OM3 and 30m OM4 or OM5 runs.
- QSFP-100G-SR-S and QSFP-100G-SR1.2 use duplex LC cabling, so they belong in a different patch-panel and fiber-count plan from SR4 MPO optics.
- Confirm the host compatibility result and remote optic before checking price, stock, warranty handling, or global shipping timing.
Selection Guide
1. Choose it for MPO SR4 multimode links
Use QSFP-100G-SR4-S when the requirement is a Cisco 100G SR4 optic and the installed fiber path is a 12-fiber MPO multimode run within the documented reach.
2. Do not substitute by speed alone
Other Cisco 100G short-reach optics may share the same 100G rate but use LC connectors, BiDi signaling, shorter reach, or different wavelength behavior. Match the fiber connector and remote transceiver before approving the line item.
3. Check the fiber grade and distance
Use Cisco’s documented reach values when reviewing the physical path: 70m on OM3, 100m on OM4, and 100m on OM5. Longer multimode requirements should be reviewed against a different Cisco optic family.
4. Validate platform support before release
Confirm the target Cisco switch, router, line card, port type, and software release in Cisco compatibility documentation before the purchasing team requests a final quote.
