SFP-25G-AOC3M Description
SFP-25G-AOC3M is a Cisco 25GBASE-AOC SFP28 active optical cable assembly for 25 Gigabit Ethernet links between supported Cisco SFP28 host ports. It provides a fixed 3-meter SFP28-to-SFP28 optical cable connection with an orange pull tab, 1W maximum power consumption, commercial 0 to 70 degrees C operating temperature, and host-port FEC requirements of BASE-R FEC or RS-FEC, making it a BOM-specific 25G cable option for Cisco switching, wireless controller, and UCS fabric interconnect environments where Cisco compatibility documentation confirms support.

Application Scenarios
SFP-25G-AOC3M fits short Cisco SFP28 cabling paths where a 2-meter AOC does not reach cleanly through the cable manager and a 4-meter assembly would add unnecessary slack.
Cisco lists SFP-25G-AOC3M in the supported 25GBASE SFP model table for the Catalyst CW9800M Wireless Controller, giving buyers a documented controller-side support example before the cable is ordered.
Cisco UCS 6400 Series documentation includes SFP-25G-AOC3M in its SFP28 25G cable table. Keep that server-access line item distinct from 25G copper DACs because the part family and FEC planning are different.

- In a SFP-25G-AOC3M vs SFP-25G-AOC2M comparison, the table difference is fixed length: SFP-25G-AOC3M is the orange-tab 3-meter AOC and SFP-25G-AOC2M is the brown-tab 2-meter AOC.
- The SFP-25G-AOC3M difference from SFP-H25G-CU3M is the cable family at the same 3-meter length, because the current SKU is active optical cable while SFP-H25G-CU3M is passive copper.
- For buyers deciding which model to choose, first keep the media family aligned with the Cisco host record, then choose the length and FEC behavior shown in the comparison table.
Selection Guide
1. Choose the 3-meter AOC for measured short routes
Select SFP-25G-AOC3M when the cabling schedule calls for Cisco 25GBASE-AOC SFP28 media and the installed path has been measured for a fixed 3-meter assembly.
2. Drop to 2 meters only when the route is tight
Use SFP-25G-AOC2M when the same Cisco AOC family is required but cable management leaves no practical need for the extra meter.
3. Separate same-length copper from the AOC order
SFP-H25G-CU3M shares the 3-meter length and orange receiving cue, but it changes the BOM to 25GBASE-CR1 passive copper and should not be substituted for this AOC without design review.
4. Confirm the Cisco host and FEC settings
Verify the target Cisco platform, port type, software context, and BASE-R FEC or RS-FEC support before releasing SFP-25G-AOC3M for quote or receiving.
Ordering Checklist
|
Review Area |
Confirmation |
Procurement Risk |
|---|---|---|
|
Media family |
Design records call for 25GBASE-AOC SFP28 active optical cable |
Avoids replacing the AOC with a same-length 25GBASE-CR1 copper DAC |
|
Three-meter path |
Rack route, cable manager path, and service loop are checked against a fixed 3-meter assembly |
Reduces length mismatch during installation staging |
|
Cisco host support |
Cisco compatibility documentation or platform documentation covers the intended host, port, and software context |
Keeps the cable inside Cisco’s support boundary for the selected SFP28 endpoint |
|
FEC planning |
Host ports support BASE-R FEC or RS-FEC as required for Cisco SFP-25G AOC links |
Aligns link turn-up with Cisco’s documented AOC FEC requirement |
|
Power and temperature |
Port planning accepts 1W maximum consumption and commercial 0 to 70 degrees C operation |
Avoids use outside Cisco’s published electrical or temperature range |
|
Receiving cue |
Orange pull tab is checked after the exact PID has been scanned |
Color is useful for visual inspection but cannot replace part-number verification |

We compared notes after the sales call — same level of expertise as our top distributors. Minor delay in delivery, but everything was in order.
Reached out months later for a related question. They picked up the conversation seamlessly. Wish the lead time was a bit shorter, but product quality made up for it.
Hard to find anything to complain about.
Calibrating… the network. These cables are precise. Good shipping speed.
