SFP-H25G-CU5M Description
SFP-H25G-CU5M is a Cisco 25GBASE-CR1 SFP28 passive copper direct-attach cable for fixed 5-meter 25 Gigabit Ethernet links between supported Cisco SFP28 host ports. It provides an SFP28 connector at each end, uses a passive copper DAC assembly, and is identified in Cisco documentation with a gray pull tab or bail latch, 0.1W maximum power consumption, commercial 0 to 70 degrees C operation, and an RS-FEC requirement for this 5-meter copper cable. For buyers matching a 25G cable BOM, this SKU is used where Cisco host compatibility and software release support are confirmed through Cisco transceiver compatibility and platform documentation.

Application Scenarios
SFP-H25G-CU5M fits Cisco SFP28 copper runs where a 4-meter cable is too short but the design still calls for a passive direct-attach assembly instead of active optical media.
Cisco Catalyst 9200 release notes list SFP-H25G-CU5M for C9200L Multigigabit Ethernet models with 25G uplinks, while Catalyst 9300 release notes list it under the C9300-NM-2Y 25G uplink module context.
Cisco UCS VIC documentation lists SFP-H25G-CU5M as a 25GBASE-CU SFP28 direct-attached copper cable and attaches release and firmware conditions to VIC 1455, VIC 1457, and VIC 1467 paths.

Ordering description |
25GBASE-CR1 SFP28 Passive Copper Cable, 5-meter |
25GBASE-CR1 SFP28 Passive Copper Cable 4-meter |
25GBASE-CR1 SFP28 Passive Copper Cable, 3-meter |
25GBASE-AOC SFP28 Active Optical Cable, 5-meter |
- In a SFP-H25G-CU5M vs SFP-H25G-CU4M comparison, both are RS-FEC passive copper DACs with 0.1W maximum power, but the current SKU changes the fixed length from 4 meters to 5 meters and the marker from green to gray.
- The SFP-H25G-CU5M difference from SFP-H25G-CU3M is the combination of longer copper reach and RS-FEC handling; the 3-meter passive copper PID is listed with BASE-R FEC.
- SFP-H25G-CU5M vs SFP-25G-AOC5M is a same-length comparison between passive copper and active optical assemblies, with a different cable family and maximum power value.
- For which model to choose, match the table entries to the required length, passive copper or active optical media, host FEC setting, and Cisco compatibility result.
Selection Guide
1. Use the 5-meter passive copper PID for the longest Cisco 25G DAC run
Choose SFP-H25G-CU5M when the measured SFP28-to-SFP28 path needs a fixed 5-meter copper assembly and the host ports support RS-FEC.
2. Keep 4-meter copper orders separate from 5-meter receiving
SFP-H25G-CU4M shares the same passive copper family and RS-FEC requirement, but it is a shorter line item with a green marker instead of the gray SFP-H25G-CU5M marker.
3. Select the AOC only when the BOM calls for active optical media
SFP-25G-AOC5M has the same 5-meter length and gray marker, but Cisco identifies it as an active optical cable assembly with a 1W maximum power value.
4. Verify host and software boundaries before approval
Check the switch model, 25G uplink module, UCS adapter, fabric interconnect, firmware level, and Cisco compatibility entry before approving SFP-H25G-CU5M for the deployment.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Receiving identity |
SFP-H25G-CU5M appears on the purchase line, carton label, and intake record |
A one-character or length change can turn the order into another 25G copper or AOC PID |
|
Installed path length |
Cable managers and bend space still leave a real 5-meter direct-attach route |
This cable cannot be shortened, extended, or converted after receipt |
|
RS-FEC readiness |
Both endpoint ports are approved to use RS-FEC with the 5-meter copper entry |
The 5-meter DAC is not in the shorter BASE-R FEC group |
|
Copper versus AOC |
The BOM calls for 25GBASE-CR1 passive copper, not a 25GBASE-AOC active optical assembly |
SFP-25G-AOC5M matches the length and gray marker but uses another media class and power value |
|
Catalyst platform entry |
The planned C9200L 25G uplink or C9300 plus C9300-NM-2Y path is covered by Cisco release-note context |
Platform support is tied to the exact switch and uplink-module path |
|
UCS firmware path |
VIC 1455, VIC 1457, or VIC 1467 use is checked against the Cisco UCS release notes in the VIC data sheet |
Cisco lists UCSM, CIMC, and VIC firmware boundaries for this PID |
|
FCoE software condition |
Any FCoE traffic plan includes the host software support Cisco requires |
The cable PID alone does not confirm an FCoE-ready host stack |
