WCI QSFP-100G-LR4-S-WC 100G 10km 1310nm QSFP28, Cisco Compatible

QSFP‑100G‑LR4‑S‑WC — 100GBASE‑LR4 10km QSFP28 Optical Transceiver

The Whaley Communications QSFP‑100G‑LR4‑S‑WC is a high‑performance, long‑reach 100GBASE‑LR4 QSFP28 optical transceiver engineered for reliability in enterprise, data center, and service‑provider networks. Designed as a drop‑in alternative to OEM modules, it delivers full compatibility with major switch and router platforms while maintaining exceptional optical performance and long‑term stability.

Built for 100‑gigabit deployments over single‑mode fiber (SMF), this module uses 4×25G LAN‑WDM channels multiplexed into a single LC duplex interface, supporting distances up to 10 kilometers. Whether you’re upgrading spine‑leaf fabrics, expanding aggregation layers, or standardizing on 100G long‑reach optics, the QSFP‑100G‑LR4‑S‑WC provides the performance and interoperability you expect — without the OEM price tag.
