Cisco QSFP-4SFP10G-CU2M 40G QSFP+ to 4x10G SFP+ Breakout Cable (2 Meter, Passive Copper)
Brand: Cisco (or compatible) · SKU: QSFP-4SFP10G-CU2M · MPN: QSFP-4SFP10G-CU2M · Category: Networking
The Cisco QSFP-4SFP10G-CU2M is a 2-meter passive Direct Attach Copper (DAC) breakout cable that allows for seamless connectivity between a 40 Gigabit (40Gbps) QSFP+ port on one end and four separate 10 Gigabit (10 Gbps) SFP+ ports on the other end. It provides 4x 10Gb/s throughput for 2m interconnection with high speed twin-axial copper cable. This cable is a cost-effective solution for short-range interconnections within equipment rooms of telecom operators or data centers. It is fully compliant with QSFP+ Multi-Source Agreement (MSA), IEEE 802.3ae 10GBASE-CR and SFI standard. Compatible versions often use 30AWG twin-axial copper cable.
