This article covers 10G SFP+ Twinaxケーブル ダイレクトアタッチ 銅(DAC) パッシブケーブル 0.25m (0.82フィート) Cisco SFP-H10GB-CU0.25M Meraki Ubiquiti UC-DAC-SFP+ Mikrotik Intel Fortinet Netgear D-Linkなど用 2個パック.

Overview

This product is a 10G SFP+ Twinax Direct Attach Copper (DAC) cable, 0.25m, in a 2-pack. It is passive type, requiring no power, and provides 10 Gigabit Ethernet connectivity over short distances. Compatible with major networking brands such as Cisco, Meraki, Ubiquiti, Mikrotik, Intel, Fortinet, and more, it is ideal for rack-internal connections in data centers and server rooms. The 30AWG thin cable makes routing easy and convenient for connecting adjacent switches and NICs.

Connectivity & Compatibility

Connectors are SFP+ to SFP+, compliant with 10GBase-CU standard. As a passive cable, no transceiver modules are needed; plug directly into SFP+ ports. Supported devices include Cisco SFP-H10GB-CU0.25M, Meraki, Ubiquiti UC-DAC-SFP+, Mikrotik, Intel, Fortinet, Netgear, D-Link, Supermicro, TP-Link, Quanta, Solarflare, PaloAlto, F5, and many others. At only 0.25m (approx. 0.82ft), it is designed specifically for within-rack connections. Uses 30AWG conductors, impedance 100Ω.

Market position is entry to mid-range, offering a cost-effective alternative to original-brand cables while claiming to pass signal integrity tests (TDR, VNA).

Best Use Cases

  • Data center operators: Ideal for short connections between switches and servers within the same rack, offering lower power consumption and cost compared to optical transceivers.
  • Home lab enthusiasts: Convenient for building 10GbE networks, connecting switches directly to NICs. The 2-pack provides a spare and is budget-friendly.
  • Network engineers: Useful for temporary connections or testing setups, with quick availability and extensive compatibility list.
  • However, not suitable for long distances (3m+) or environments requiring optical fiber. Ensure that the SFP+ ports on your devices support passive DAC cables.
