CPAK-100G-SR4 Overview
The Cisco CPAK-100G-SR4 module delivers 100Gbps Ethernet connectivity over 100m OM4 or 70m OM3 parallel multimode fiber with MPO connectors. It multiplexes 25Gbps lanes onto 850nm wavelengths.
This SR4 module maps a 100GbE signal across 4 lanes capable of 25.78125Gbps each. It enables hyper-scale 100G aggregation in data centers using compact CPAK pluggables with existing MMF cabling.
The CPAK-100G-SR4 also helps enable an upgrade from 40G to 100G capacity while reusing OM3/OM4 infrastructure for investment protection. Its small CPAK footprint provides high density 100GbE ports.
