Cisco QSFP-100G-LR4-S Compatible, 100G QSFP28 LR4 Transceiver — 10km SMF, LAN-WDM ~1310nm, Duplex LC
Warranty: Lifetime
Coded for Cisco (Arista / Juniper coding on request). Compatible with Cisco QSFP-100G-LR4-S. IEEE 802.3ba LR4 — interoperates with any standards-compliant LR4 at the far end.
Third-party 100G QSFP28 LR4 optical transceiver, fully compatible with Cisco QSFP-100G-LR4-S, for long-reach single-mode links up to 10km.
Multiplexes four LAN-WDM wavelengths around 1310nm onto a duplex single-mode pair via LC connectors, carrying full-rate 100Gb/s for campus backbones and data-center interconnect (DCI). Hot-pluggable, QSFP28 MSA compliant, DOM/DDM diagnostics. Because LR4 is IEEE-standard, it links to any compliant 100GBASE-LR4 module at the far end regardless of brand.Key Specs

EEPROM / Coding Notes
Pre-programmed to present as Cisco QSFP-100G-LR4-S. LR4 is a common interoperability optic — it links to any standards-compliant 100GBASE-LR4 module at the far end regardless of that end's brand, as long as both meet IEEE 802.3ba.
Q&A
Q: How far does LR4 reach?
A: Up to 10km over single-mode fiber.
Q: Will it interoperate with a different-brand LR4 on the other end?
A: Yes — LR4 is IEEE-standard, so any compliant 100GBASE-LR4 optic pairs with it.
Q: Single-mode or multimode?
A: Single-mode (SMF), duplex LC.
Q: Is FEC required?
A: No — standard 100GBASE-LR4 does not require host FEC.
