title: "25G DAC vs AOC vs Optical: The Total Cost of Ownership Nobody Calculates"
type: comparison
target_audience: technical
score: 9/10
---

Every data center architect has been through the DAC versus optical conversation, usually at the point where someone in procurement discovers that a passive copper DAC costs €18 while an SFP28 SR module pair costs €120 and asks why anyone would pay six times more for the same 25G connection. The answer is not obvious from a unit price comparison, and the people who answer "always use DAC" for short distances have usually never managed a large-scale cabling change, dealt with an HVAC rerouting project, or attempted to replace a failed cable in a densely packed 2U server row.

Passive 25G DAC cables — the twin-axial copper assemblies conforming to SFF-8431 and IEEE 802.3by — operate reliably to approximately 3m in the Twinax configuration and to 5m in heavier-gauge variants, with some 7m cables marketed by vendors like FS.com and Molex that work in practice only on specific platforms with aggressive equalization. Beyond 5m, attenuation at 25.78125 Gbps NRZ exceeds what most SerDes equalizers can recover reliably, and you start seeing platform-specific behavior where Arista 7050CX3 will link up with a 7m DAC that a Cisco Nexus 93180YC-EX refuses to negotiate. Electrically, a passive DAC consumes zero power from the SFP28 cage — the optical port power budget shows 0W per lane. This is genuinely attractive in a high-density compute cluster where the sum of 500 server uplinks represents meaningful power and cooling overhead.

The physics problem with copper at 25G manifests as cable management complexity that doesn't show up in the procurement spreadsheet. A 5m 25G DAC cable has a minimum bend radius of approximately 40mm and weighs roughly 120g. A rack with 48 DAC connections to an adjacent ToR switch accumulates 5.76kg of cable mass, all of which has to be managed with cable arms, Velcro, and careful routing to avoid violating the bend radius at patch panel exits. More critically, passive DAC cables cannot be rerouted to a different rack without swapping the entire fixed-length assembly — and DAC cables are non-field-serviceable. When the 25G leaf switch in row 7 is replaced with a 100G capable switch during a refresh cycle and the new switch is 3 racks away instead of 1, every DAC cable becomes scrap. The per-unit cost of €18 that seemed so attractive in year one becomes €18 x 48 ports in disposal cost during the refresh, plus €18 x 48 for new cables of the correct length, plus roughly 2 hours of cabling labor per rack at €80/hour for a skilled data center technician.

AOC (Active Optical Cable) splits the difference in an uncomfortable way. An AOC for 25G — physically an SFP28 module at each end bonded permanently to a multi-strand OM3 fiber cable — costs approximately €55-80 for a 3m assembly from quality vendors like Flexoptix P.10811 series or Lumentum. The optical cable portion can be routed around bends as tight as 5mm (vs 40mm for copper Twinax), the cable weighs approximately 30g for a 5m assembly versus 150g for a DAC equivalent, and AOC works to 30m reliably on OM3. These properties make AOC genuinely superior for high-density cabling where cable management is constrained, particularly in blade server environments where cables must traverse tightly managed channels.

The trap with AOC is the non-field-serviceability problem, now worse than DAC because the fiber plant is integrated into a relatively expensive assembly. When an AOC fails — the most common failure mode is the active element at one end developing a fault, which happens at a rate of approximately 0.8-1.5% per year based on field data from large deployments — you lose the entire €70 assembly and cannot reuse any component. Compare this to a discrete optical solution: SFP28 SR module (Flexoptix P.10701 or equivalent) plus a 3m duplex OM4 patch cord costs approximately €50 per module (€100/pair) plus €8-12 for the patch cord. When the SFP28 SR fails — field MTBF on quality modules runs 5-7 years — you replace the €50 module, not the fiber. The patch cord, if undamaged, serves another 15-20 years.

The 7-year TCO model is where optical wins decisively for anything larger than a pilot deployment. Assume a 48-port server-to-leaf interconnect with an average distance of 5m, requiring one link refresh over 7 years (swap rate of 0.8%/year = roughly 3 port failures per year, 21 total over 7 years). For DAC: €18 initial cost x 48 = €864 plus one full cable replacement at switch refresh in year 4 at €18 x 48 = €864 again, total €1,728 plus 2 hours labor for the refresh at €160 = €1,888. For AOC: €70 x 48 = €3,360 initially plus €70 x 21 failure replacements = €1,470, plus the year-4 refresh at €70 x 48 = €3,360, total €8,190. For optical (SFP28 SR + patch cord): €50 module + €10 cord x 96 modules + 48 cords = €5,280 initial, plus €50 x 21 module failures = €1,050, plus year-4 refresh requires only new optics on the new switch (the fiber plant stays), so €50 x 48 modules for the new switch = €2,400. Total optical 7-year cost: €8,730.

That calculation looks like AOC beats optical narrowly — and for a static 48-port deployment it might. The model collapses when you introduce moves, adds, and changes. In a production data center, roughly 20-25% of server connections move or change distance within any given year. For 48 ports, that's 10-12 DAC or AOC swaps annually just from MAC activity, each requiring a physically matching replacement. The DAC inventory problem is concrete: you need to stock 1m, 2m, 3m, 5m variants. A stocking policy for 4 DAC lengths costs more in inventory carrying cost than the difference between DAC and optical becomes irrelevant. With optical, you reuse the fiber plant and swap only the SFP28 modules, which are all the same SKU regardless of reach.

The power differential bears quantification for large deployments. Passive DAC: 0W per link, effectively zero. AOC: approximately 1W total (both active ends combined), so 0.5W per SFP28 equivalent position. SFP28 SR: approximately 1.0W per module at full output, 2.0W per link pair. At 1,000 links (a modest-sized leaf layer), optical consumes 2,000W more than DAC — roughly €1,400 per year in electricity at European data center power costs of €0.10/kWh PUE-adjusted. This is real money but it needs to be compared against the infrastructure flexibility cost of locking yourself into a fixed-length copper plant that cannot adapt to network topology changes without full cable replacement.

The structured cabling argument often gets inverted in these discussions. OM4 multimode fiber installation for a 500-server deployment costs approximately €25-35 per port in properly installed horizontal cabling — a one-time infrastructure investment that can support OM4-compatible speeds from 10G through to 100G (SFP28 SR) and potentially 200G (SFP56) without touching the fiber plant. That €25/port paid once amortizes over 15 years. The DAC solution defers that infrastructure investment but forces a de-facto fiber installation during every rack refresh cycle as cable lengths change, at a per-instance cost higher than the original structured cabling would have been.

The correct answer for server-to-ToR connections is: DAC for static, single-rack, cost-constrained deployments with no expected topology changes; optical for any environment with active MAC activity, cross-aisle connections, or a service life beyond 3 years. AOC occupies a narrow wedge where you need 10-30m reach and don't want to invest in structured cabling infrastructure — typically useful for storage interconnects to NAS arrays on the opposite side of a raised floor.
