Cisco NC55-MPA-4H-HD-S= 4x100G QSFP28 Temp-Hardened MPA | Service Provider

Maintain high-speed transport where environmental conditions can challenge standard modules. The Cisco NCS 5500 4x100G QSFP28 Temp-Hardened MPA is built to extend 100G connectivity into service-provider edge deployments that need more tolerance for temperature variation and less compromise on port density. With 4 x 100G QSFP28 ports, this module is suited to aggregation points, remote edge sites, and transport nodes that must keep critical links active without moving to a larger chassis than necessary. The temp-hardened design is especially valuable when equipment is installed in locations with tighter thermal control margins or where operational continuity matters more than minimizing upfront hardware cost. For infrastructure teams, the value is in keeping a familiar 100G architecture while improving deployment flexibility. It supports a cleaner standardization strategy across edge sites and helps preserve service quality in conditions where ordinary modules may be less suitable. That makes it a practical choice for networks that need dependable 100G capacity in demanding physical environments.
