Cisco QSFP-100G-SR4-S Compatible, 100G QSFP28 SR4 Transceiver — 100m OM4 MMF, 850nm, MPO-12
Warranty: Lifetime
Coded for Cisco (Arista / Juniper / Mellanox coding on request). Compatible with Cisco QSFP-100G-SR4-S.
Third-party 100G QSFP28 SR4 optical transceiver, fully compatible with Cisco QSFP-100G-SR4-S, for short-reach in-datacenter 100G links. Carries 100Gb/s across four parallel 25G channels at 850nm over multimode fiber — 100m on OM4, 70m on OM3 — via an MTP/MPO-12 connector. Hot-pluggable, QSFP28 MSA (SFF-8665) compliant, full DOM/DDM digital diagnostics, 3.5W max. Ideal for top-of-rack to leaf/spine, 100G server uplinks, and — with an MPO-to-LC breakout — 100G-to-4x25G runs that attach directly to our 25G SFP28 optics and breakout DACs.

EEPROM / Coding Notes
Factory pre-programmed and serialized to present as Cisco QSFP-100G-SR4-S; the host reads the coded EEPROM (SFF-8636/8665) and initializes identically to OEM. State the required platform coding at checkout if not default-Cisco; Arista/Juniper/Mellanox codings available.
Q&A
Q: Is this compatible with Cisco Nexus switches?
A: Yes — coded to match Cisco QSFP-100G-SR4-S; initializes identically on 100G-capable Nexus platforms.
Q: What is the max distance?
A: 100m over OM4 multimode, 70m over OM3.
Q: Can I use it for 100G-to-4x25G breakout?
A: Yes, with an MPO-to-LC breakout assembly; it pairs with our 25G SFP28 optics.
Q: Does it support DOM?
A: Yes, full digital diagnostics via I2C.
