SFP-H10GB-CU1M Description
SFP-H10GB-CU1M is a Cisco 10GBASE-CU SFP+ passive Twinax copper cable assembly for short 10 Gigabit Ethernet links between supported Cisco SFP+ ports. It is the 1 m member of Cisco's SFP-H10GB-CU cable family, with SFP+ connectors at both ends, 30 AWG copper construction, a beige bail latch, and 0.1W maximum power consumption. Use it for rack-level switch, server, or fabric-interconnect connections where the Cisco host platform and software release support this exact passive DAC PID through Cisco's transceiver compatibility guidance.

Application Scenarios
Use SFP-H10GB-CU1M when two supported Cisco SFP+ ports are close enough for a 1-meter direct-attach passive Twinax cable. The fixed length makes it a receiving-sensitive part number because a 1.5-meter, 2-meter, or active 7-meter cable changes the installed cable plan.
Cisco Catalyst 9200 release notes list SFP-H10GB-CU1M among supported cable options for C9200L Multigigabit Ethernet models with 10 Gigabit uplinks. The target switch model, SFP+ port role, software context, and TMG result should still be checked before procurement.
Cisco UCS 6300 Series documentation lists SFP-H10GB-CU1M as a 1-meter passive 10GBASE-CU SFP+ cable. Keep it separate from 10GBASE-AOC cables and from active Twinax lengths when preparing spare kits or replacement shipments.

- In a SFP-H10GB-CU1M vs SFP-H10GB-CU1-5M comparison, both are passive 30 AWG Twinax cables, but the current SKU is the 1-meter order and SFP-H10GB-CU1-5M is the 1.5-meter order.
- The SFP-H10GB-CU1M difference from SFP-H10GB-CU2M is fixed length and latch color: Cisco lists SFP-H10GB-CU1M at 1 meter with a beige latch and SFP-H10GB-CU2M at 2 meters with a brown latch.
- SFP-H10GB-CU1M vs SFP-H10GB-ACU7M is a passive-versus-active copper comparison, with SFP-H10GB-CU1M listed at 0.1W and SFP-H10GB-ACU7M listed at 1W.
- For which model to choose, match the exact fixed length, passive or active Twinax family, and Cisco host compatibility before the SKU is released for purchase.
Selection Guide
1. Select it for a 1-meter passive DAC route
Choose SFP-H10GB-CU1M when the cable path is very short and the design calls for Cisco 10GBASE-CU SFP+ passive Twinax rather than optical or active copper cabling.
2. Move to another passive length only when the route needs it
Use SFP-H10GB-CU1-5M or SFP-H10GB-CU2M when the dressed route cannot be served by the 1-meter cable. These nearby SKUs stay passive but change the fixed length and receiving markers.
3. Keep active Twinax out of short passive orders
SFP-H10GB-ACU7M belongs to the active copper group and carries a different power value. It should not replace SFP-H10GB-CU1M unless the bill of materials explicitly requires the 7-meter active cable.
4. Verify host support before purchase approval
Confirm the Cisco platform, SFP+ port type, software context, TMG compatibility result, and any required Version -02 DAC qualification before adding SFP-H10GB-CU1M to the order.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Cable medium |
10GBASE-CU passive Twinax copper cable assembly |
Keeps the order aligned with passive DAC cabling rather than AOC or active copper |
|
Fixed length |
1-meter installed route after cable-management slack |
Confirms the physical path fits this SKU without forcing a different fixed-length cable |
|
DAC version |
Version -02 or later when all-platform Cisco qualification is required |
Aligns the order with the Cisco datasheet qualification note for this DAC cable |
|
Host compatibility |
Cisco platform, SFP+ port type, software context, and TMG support |
Verifies the target device supports the exact passive copper cable |
|
Power and environment |
0.1W maximum power and commercial operating temperature class |
Checks the port and site conditions against Cisco-listed ratings |
|
Receiving markers |
30 AWG passive Twinax construction and beige bail latch |
Helps distinguish the 1-meter passive cable from longer CU and ACU alternatives |
