SFP-H10GB-CU4M Description
SFP-H10GB-CU4M is a Cisco 10GBASE-CU SFP+ passive Twinax copper cable assembly for short 10 Gigabit Ethernet connections between supported Cisco SFP+ ports. This 4-meter cable uses an SFP+ to SFP+ interface, is listed by Cisco as a passive Twinax assembly with 24 AWG or 26 AWG conductors, has a green bail latch, and is specified for commercial 0 to 70 degrees C operation with 0.1W maximum power consumption. It fits data center and fabric-interconnect BOMs that need a Cisco-confirmed copper 10G link length, with host support checked against Cisco compatibility documentation such as the Transceiver Module Group Compatibility Matrix.

Application Scenarios
SFP-H10GB-CU4M fits Cisco SFP+ copper designs where a 4-meter fixed-length DAC is needed for a dressed route inside a rack row or between nearby cabinets. It should be staged as passive Twinax copper rather than fiber or active optical cable.
Cisco UCS 6600 documentation lists SFP-H10GB-CU4M under 10GbE with all ports for the UCS FI 6652. The order still needs the exact fabric-interconnect model, port role, and Cisco support matrix result checked before the cable is released.
The green latch and 24 AWG or 26 AWG listing help separate SFP-H10GB-CU4M from the orange 3-meter SFP-H10GB-CU3M and gray 5-meter SFP-H10GB-CU5M. Use those physical markers during receipt when multiple Cisco passive DAC lengths are on the same BOM.

- In a SFP-H10GB-CU4M vs SFP-H10GB-CU3M comparison, the table separates the current 4-meter green-latch cable from the 3-meter orange-latch cable.
- The SFP-H10GB-CU4M difference from SFP-H10GB-CU5M is length and latch color: both are passive 24 AWG or 26 AWG Twinax assemblies, but the adjacent SKU is the 5-meter gray-latch order.
- SFP-H10GB-CU4M vs SFP-H10GB-ACU7M is a passive-versus-active copper comparison with different length, power, gauge, and latch-color values.
- For which model to choose, match the measured path to the fixed cable length first, then confirm passive or active copper type and Cisco host support.
Selection Guide
1. Match the 4-meter path before choosing the PID
Use SFP-H10GB-CU4M when the installed route needs a 4-meter Cisco SFP+ passive Twinax assembly after cable dressing and service allowance are considered.
2. Move to adjacent passive SKUs only for length changes
Choose SFP-H10GB-CU3M for a shorter 3-meter path or SFP-H10GB-CU5M for a longer 5-meter path. These are neighboring passive DAC orders with different physical identifiers.
3. Keep active copper out of passive DAC substitutions
SFP-H10GB-CU4M is a 0.1W passive cable. A move to SFP-H10GB-ACU7M changes the cable family to active copper and changes the listed power value to 1W.
4. Confirm host support with the Cisco matrix
Check the switch, router, UCS adapter, or fabric interconnect against Cisco compatibility data before placing SFP-H10GB-CU4M on a production BOM.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Route measurement |
The rack or cabinet path needs a 4-meter fixed assembly after dressing |
Prevents a DAC that is too short or creates hard-to-manage slack |
|
Cable construction |
The design calls for 10GBASE-CU passive Twinax copper with SFP+ ends |
Avoids mixing passive DAC, active copper, and active optical cable families |
|
Host validation |
The Cisco platform, port type, software context, and TMG result are checked |
SFP+ connector fit does not prove platform support |
|
Power and temperature |
0.1W maximum power and COM 0 to 70 degrees C operation fit the site |
Aligns the order with Cisco-listed electrical and environment values |
|
Receiving marker |
Green bail latch and 24 AWG or 26 AWG construction are inspected on arrival |
Gives warehouse teams a physical check against adjacent passive lengths |

We switched from another reseller because of inconsistent quality. No such problems here.
Layer23 has my full endorsement as a hardware supplier.
Setup was straightforward. Documentation was helpful when we needed it. Invoice formatting was a bit different from what our AP system expects, but workable.
Hard to find genuine 4M cables in stock sometimes. Layer23 came through.
Correct part delivered. Serial numbers match the invoice. Good B2B partner.
