QSFP-100G-DR-S Description
QSFP-100G-DR-S is the Cisco 100GBASE-DR QSFP transceiver for 500-meter single-mode links using duplex LC connectors.
It is a good fit when the design needs a short single-mode 100G DR link and wants LC patching instead of MPO parallel fiber. Compare it carefully with PSM4, FR, and LR optics, since those modules differ by connector, reach, optical specification, and power profile.
Before ordering, confirm the Cisco host platform, G.652 fiber path, far-end optic, and whether the link is a straight 100G DR connection or part of a 400G DR4 breakout design. Layer23-Switch can help check price, stock, warranty support, shipping timing, and compatibility.

Application Scenarios
Deploy QSFP-100G-DR-S where the 100G path uses duplex LC single-mode cabling and the measured fiber route is within Cisco’s 500 m DR reach.
This module can be part of a breakout plan from a Cisco-supported 400GBASE-DR4 optic to four 100G DR links. Confirm the breakout cabling and the remote transceiver before the quote is finalized.
Keep QSFP-100G-DR-S distinct from PSM4, FR, LR, CWDM4, and SR optics in receiving and maintenance stock. The product names look close, but the connector, reach, host support, and far-end optic requirements can change the bill of materials.

- QSFP-100G-DR-S is the LC single-mode option for 500 m Cisco 100G DR links.
- QSFP-100G-PSM4-S also reaches 500 m over single-mode fiber, but its MPO connector and parallel fiber design require a different patching plan.
- QSFP-100G-FR-S keeps the LC single-mode connector style while extending the documented reach to 2 km.
- QSFP-100G-LR-S belongs in 10 km single-mode planning and should not be substituted when the order specifically calls for 100GBASE-DR optics.
Selection Guide
1. Choose it for LC 100G DR links inside 500 m
Select QSFP-100G-DR-S when the deployment requires Cisco 100GBASE-DR, duplex LC cabling, G.652 single-mode fiber, and a short-reach 500 m optical path.
2. Do not treat all 500 m 100G optics as interchangeable
PSM4 and DR can share the same published reach, but the cabling layout is different. Confirm whether the site uses duplex LC or MPO fiber before approving the part number.
3. Confirm the remote optic and breakout plan
For 400G-to-100G breakout, verify that the far end follows Cisco-supported 400GBASE-DR4 interoperability and that the breakout cable maps correctly to the intended 100G port.
4. Validate host support before purchase
Check Cisco compatibility data for the exact platform, port, and software release, then confirm Layer23-Switch quote, stock availability, warranty support, and shipping destination.
