Description

QSFP-100G-ZR4-S refers to a 100 Gigabit Ethernet Quad Small Form-Factor Pluggable (QSFP) transceiver module designed for long-reach optical communication. Specifically, “ZR4” indicates it uses four wavelengths to transmit 100GbE over single-mode fiber, supporting distances up to 80 kilometers. The “-S” likely denotes a specific vendor or specification variant. “X2” indicates you have two of these modules. These modules are crucial for high-capacity data center interconnects and long-haul telecommunications, enabling reliable and efficient transmission of large amounts of data over extended distances.
