Cisco Compatible QSFP-40G-ZR4 | 40GBASE-ZR4 QSFP+ Transceiver LC SMF 80km

Cisco Compatible QSFP-40G-ZR4 40GBASE-ZR4 QSFP+ Optical Transceiver (LC Duplex, 1310nm, 80km)

Product Overview

The Cisco compatible QSFP-40G-ZR4 optical transceiver is a high-performance 40Gbps module engineered for ultra long-distance transmission over single-mode fiber (SMF). Utilizing advanced LAN-WDM technology, it multiplexes four optical lanes into a single duplex fiber pair, enabling efficient high-speed communication across extended distances.

Operating within the 1310nm wavelength range, this module supports transmission distances up to 80 kilometers, making it ideal for telecom backbone networks, long-haul data center interconnect (DCI), and inter-city enterprise connectivity.
