Cisco QSFP-100G-ZR4-S Compatible 100GBASE-ZR4 QSFP28 1310nm 80km OS2 DOM Duplex LC SMF Optical Transceiver Module

100G QSFP28 ZR4 optical transceiver

The 100GBASE-ZR4 QSFP28 module is built for genuinely long spans: up to 80 kilometers of single-mode fiber between switches, routers and transport equipment. An integrated semiconductor optical amplifier boosts the four LAN-WDM lanes so the link budget closes without external amplification.

Operating in the 1310nm window with a duplex LC interface, the ZR4 complies with SFF-8665, SFF-8636 and the relevant QSFP28 MSA documents, and exposes full digital diagnostics over I2C for per-lane monitoring. It gives operators and large enterprises a cost-effective alternative to dedicated DWDM systems for inter-city and cross-border links, and every module is aged and traffic-tested before shipment to our regional customers.
