Cisco CRS-MSC-140G Modular Services Card, manufactured by Cisco, is a modular form factor line card supporting 140-Gbps transmission speed. It interfaces with supported modules including 1x100GbE and multiple XFP-based ports such as 14x10GbEWL-XFP and 20x10GbE-WLXFP.

The CRS-MSC-140G is compatible with the Cisco CRS-3 line-card chassis and can be used in the Cisco CRS-1 chassis when equipped with upgraded 140-Gbps fabric cards. Designed for carrier-grade deployments where scalable capacity per slot is required, it supports high-throughput applications across various port densities using relevant interface modules. Power supply depends on host chassis configuration; mounting style aligns with standard internal module insertion into corresponding slots within approved systems.
