25GBASE-CR1 passive DAC — SFP28 to SFP28 copper twinax, not optical AOC

Cisco SFP-H25G-CU2M — 25G SFP28 passive Direct Attach Copper cable, 2 meter

Cisco Part Number: SFP-H25G-CU2M
Common aliases / related PIDs: SFP-H25G-CU1M · SFP-H25G-CU2.5M · SFP-H25G-CU3M · 25GBASE-CR1
Description: Passive SFP28-to-SFP28 twinax DAC for short-reach 25 Gigabit Ethernet (25GBASE-CR1)

This is a genuine Cisco 2-meter 25GBASE-CR1 passive copper DAC — SFP28 connectors on both ends, brown pull tab per Cisco’s length color code. It is the low-latency, near-zero-power way to link 25G SFP28 ports inside a rack or to an adjacent rack without optics or fiber plant.

Lifetime warranty from Resilient Tec.

Going into You need
Cisco 25G SFP28 ports, ~2 m reach, no FEC required on host SFP-H25G-CU2M — this product
Same platforms, 1 m intra-rack SFP-H25G-CU1M (1 m)
Same platforms, 2.5 m (requires BASE-R / FC-FEC on host) SFP-H25G-CU2.5M
Compatible (third-party) 1 m DAC at a lower ticket SFP-H25GB-CU1M Compatible
Longer reach or fiber plant instead of copper DAC 25G SFP28 SR/LR optics + fiber — not this cable

Length and FEC matter. Cisco rates 1 m / 1.5 m / 2 m passive DACs without host FEC; 2.5 m and 3 m require BASE-R (FC-FEC); 4 m / 5 m require RS-FEC. Confirm FEC capability on your Nexus/Catalyst hosts before ordering past 2 m.

Specification Value
Part Number SFP-H25G-CU2M
Form Factor SFP28 to SFP28
Ethernet Standard IEEE 802.3by 25GBASE-CR1
Data Rate 25 Gbps
Cable Type Passive Direct Attach Copper (twinax DAC)
Cable Length 2 meters (6.6 ft)
Wire Gauge 30 AWG (typical)
Pull Tab Color Brown (Cisco length code)
Power Consumption Passive, ~0.1 W max
Host FEC Not required (≤ 2 m)
Operating Temperature 0°C to 70°C (commercial)
Standards IEEE 802.3by, SFF-8402, SFP28 MSA, RoHS
Compatibility Cisco switches/servers with 25G SFP28 ports (e.g. Nexus 9000/3000, Catalyst 9300/9400/9500)
Warranty Lifetime, backed by Resilient Tec
Condition New

Passive DACs draw essentially no power and add almost no latency — ideal for ToR switch-to-server and switch-to-switch links inside or between adjacent racks. They are not a substitute for SR/LR optics when you need fiber plant, longer reach, or optical isolation.

  • Genuine Cisco PID — EEPROM coded for Cisco 25G SFP28 platforms.
  • Hot-pluggable; no configuration required beyond enabling the port.
  • 2 m is the longest Cisco passive length that typically does not require host FEC.
  • New condition — factory-new inventory from Resilient Tec stock.

You have two 25G SFP28 cages. The run is about 2 meters. You want a passive copper DAC, not an AOC or optic+fiber. Your host does not need FEC for ≤ 2 m links. You specifically need the Cisco SFP-H25G-CU2M PID.

Note on Passive DAC vs Optics

Passive DACs draw essentially no power and add almost no latency — ideal for ToR switch-to-server and switch-to-switch links inside or between adjacent racks. They are not a substitute for SR/LR optics when you need fiber plant, longer reach, or optical isolation.

Good to Know

  • Hot-pluggable; no configuration required beyond enabling the port.
  • 2 m is the longest Cisco passive length that typically does not require host FEC.
  • New condition — factory-new inventory from Resilient Tec stock.
Quick Checklist — Is This the Right Cable?

You have two 25G SFP28 cages. The run is about 2 meters. You want a passive copper DAC, not an AOC or optic+fiber. Your host does not need FEC for ≤ 2 m links. You specifically need the Cisco SFP-H25G-CU2M PID.
