Cisco CPAK-100G-FR= 100G CPAK Transceiver, 2 km SMF | LC Duplex — CPAK-100G-FR=

Carry 100 GbE links farther without stepping into long-haul complexity. Cisco’s CPAK-100G-FR= transceiver is designed for 2 km operation over single-mode fiber, giving network teams a practical option for campus interconnects, metro-adjacent facilities, and data center links that need more reach than standard short-range optics. The duplex LC connection keeps deployment straightforward on established SMF infrastructure. In Cisco environments, the CPAK form factor supports high-speed connectivity while preserving the port density and platform alignment that matter in production networks. That makes this module a strong fit when you need 100 GbE performance with a reach profile that matches real-world building-to-building or room-to-room distances. Compared with lower-cost optics that may force compromises in reach or platform fit, this module is about precision. It gives you the distance, interface, and Cisco compatibility needed to keep critical links clean and predictable—without paying for capabilities you won’t use.
