Cisco SFP-25G-CU2M Full English Product Description
Product Overview
Cisco SFP-25G-CU2M is an original Cisco passive 25GBASE-CR1 SFP28-to-SFP28 direct attach twinax copper cable (Passive DAC) with a length of 2 meters. Factory pre-terminated with integrated SFP28 connectors on both cable ends. Compliant with SFP28 MSA SFF-8432 and IEEE 802.3by standards. This cost-effective, ultra-low-latency cable serves as an ideal alternative to active optical cables and optical transceivers for short-range 25-Gigabit point-to-point links within data center server racks. The 2-meter passive cable normally operates stable without mandatory RS-FEC on host ports.
Key Features
-
25.78125 Gbps Full-Duplex Transmission
Supports 25GBASE-CR1 25 Gigabit Ethernet, delivering consistent bidirectional 25G data throughput for cloud data centers, enterprise networks and high-speed storage infrastructure.
-
Passive Twinax Low-Power Architecture
No built-in signal amplification circuitry. Typical power consumption ≤ 0.1 W, minimizing power draw and heat load in high-density rack deployments.
-
Ultra-Low Transmission Latency
Direct copper signal transmission reduces signal delay significantly, perfect for high-performance computing, virtualization clusters and low-latency leaf-spine fabric networks.
-
Hot-Swappable SFP28 Interface
Standard hot-pluggable SFP28 form factor allows technicians to install or remove the cable without powering down connected switches, routers and servers.
-
Fully Shielded Twinax Cable Construction
30 AWG shielded twinaxial cable provides excellent suppression of EMI and RFI electromagnetic interference, maintaining stable signal integrity in densely wired data center environments.
-
Brown Pull Latch Design
Equipped with brown pull-tab latches for convenient insertion and extraction from SFP28 ports on network hardware.
