Brief Introduction
The CVR-4SFP10G-QSFP is a high-density breakout cable assembly designed to convert a single 40G QSFP+ port into four independent 10G SFP+ links, enabling flexible connectivity and bandwidth optimization in data centers and enterprise networks.
Detailed Description
This passive direct-attach copper (DAC) cable features a QSFP+ connector on one end and four SFP+ connectors on the other, supporting 40G to 4x10G connectivity without signal conversion. Compliant with SFF-8436 and IEEE 802.3 standards, it delivers low-latency transmission up to 5 meters while reducing power consumption and cost compared to optical transceivers. Ideal for switch stacking, server aggregation, and storage area networks.
Key Features
Breakout Functionality: Split 40G QSFP+ port into 4×10G SFP+ channels
Passive Copper Design: Zero power consumption (<0.1W), no signal conversion
Hot-Swappable: Tool-free installation with latching connectors
Low Latency: <0.1ns delay for high-frequency applications
Cost-Effective: 70% savings vs. optical transceiver solutions
Wide Compatibility: Supports Cisco Nexus, Arista, De ll, Juniper platforms
