Keep high-speed links alive across extended fiber spans with a 100G-ZR4 QSFP28 transceiver designed for demanding network interconnects. This module supports 100 Gigabit Ethernet over single-mode fiber and uses an LC connector interface, making it a practical fit for long-reach backbone, campus, and data center transport designs where link stability matters more than commodity pricing. For infrastructure teams, the value is in preserving throughput without redesigning the optical layer. ZR4-class optics are typically chosen when standard short-reach modules are not enough and when the cost of a failed link is far higher than the cost of the transceiver itself. That makes this module a strong option for procurement cycles that prioritize dependable replacement parts and predictable network behavior. AddOn Networks positions this optic as a compatible solution for the specified platform family, helping teams source the right part for maintenance, expansion, or spares inventory. If your environment depends on long-distance 100 GbE transport, this module is built to keep that path clear.
