| Product Description |
Cisco QSFP-H40G-CU3M Full English Product Description
Product Overview
Cisco QSFP-H40G-CU3M is an original Cisco 40GBASE-CR4 QSFP+ to QSFP+ Passive Direct Attach Twinax Copper Cable (Passive DAC) with a fixed length of 3 meters. This fully integrated pre-terminated twinax copper assembly comes with built-in QSFP+ connectors on both cable ends. Compliant with QSFP+ MSA SFF-8436 and IEEE 802.3ba standards, it provides cost-effective, ultra-low-latency 40-Gigabit interconnection solutions for medium-range intra-rack and adjacent cross-rack point-to-point links in enterprise and cloud data centers.
Key Features
-
40 Gbps Full-Duplex Data Transmission
Supports 40GBASE-CR4 Ethernet with four independent 10Gbps differential lanes, delivering stable bidirectional 40G throughput for leaf-spine network fabrics, switch-server interconnections and high-speed storage networking infrastructure.
-
Passive Twinax Low-Power Architecture
No built-in signal amplification circuitry. Ultra-low power consumption reduces overall power expenditure and thermal load inside densely populated server racks.
-
Ultra-Low Transmission Latency
Electrical copper transmission minimizes signal delay significantly, making it suitable for low-latency computing clusters, virtualization platforms and high-performance data center networks.
-
Hot-Swappable QSFP+ Interface
Standard hot-pluggable QSFP+ form factor allows technicians to install or remove the cable without powering down connected switches, routers and servers.
-
Fully Shielded Twinax Construction
30 AWG shielded twinax cable provides excellent suppression of EMI and RFI electromagnetic interference and near-end crosstalk, maintaining reliable signal integrity in densely cabled data center environments.
-
Color-Coded Pull Tab Design
Equipped with pull-tab latches for convenient insertion and extraction from QSFP+ ports on network hardware.
