QSFP-100G-ZR4-S — QSFP28 100 Gbps

The QSFP-100G-ZR4-S is a Cisco QSFP28 module transmitting 100 Gbps over single-mode fiber (SMF) with an LC (UPC) connector, with an exceptional reach of 80 km. This long reach sets it radically apart from short- and medium-range 100G modules, positioning it for long-distance links without intermediate optical amplification.

This transceiver targets telecom operators, ISPs, and enterprises with remote sites tens of kilometers apart requiring native 100 Gbps connectivity. Its 80 km reach covers the vast majority of metropolitan and regional links. Genuine Cisco hardware, manufacturer warranty.
