Extreme Networks 10449 Active Optical Breakout Cable

Extreme Networks 10449 is an active optical breakout cable that converts a single 100Gb QSFP28 link into two QSFP28 connections over a 20-meter fiber run. Designed for data-center interconnects, it enables a single 100G port to be extended to two downstream QSFP28 ports, preserving signal quality through embedded active electronics across the 20-meter link. The device uses optical lanes arranged to deliver two independent 100G paths while staying within a single 20 m cable, maintaining alignment with standard QSFP28 breakout configurations. In practical deployments, the breakout provides two QSFP28 endpoints at the far end from one source, allowing dual-link connectivity to compatible switches, routers, or high-density top-of-rack adapters without running separate fibers for each path. The 20-meter length supports rack-to-rack layouts in data centers where minimizing cabling footprint is important, and the assembly carries the Extreme Networks part number 10449 and is intended for environments with QSFP28 ports on both ends.
