---

The question of EDFA versus Raman comes up every time someone designs a span longer than 80 km and discovers that a single amplifier won't do what they hoped. Both technologies add gain to an optical signal without converting it to electrical form. Beyond that statement, almost everything is different — the physics, the component requirements, the noise characteristics, the deployment model, and the failure modes.

## How EDFA Works and Why It's Dominant

An Erbium-Doped Fiber Amplifier runs signal light through a short segment of silica fiber that has been doped with erbium ions — typically 10 to 30 meters of fiber with erbium concentration around 100–1000 ppm. A pump laser, usually operating at 980 nm or 1480 nm, excites the erbium ions to a higher energy state. When a signal photon in the C-band (1530–1565 nm) or L-band (1565–1625 nm) passes through, it triggers stimulated emission from the excited erbium ions, producing a second photon of identical wavelength and phase. That's optical amplification.

The practical implications of this mechanism: EDFA gain is confined to the erbium emission spectrum, which maps almost exactly onto the C-band and L-band — the same bands used by DWDM systems. This alignment is not a coincidence; it's a significant reason why DWDM developed the way it did. Typical gain values for a single-stage EDFA are 20–35 dB with output power up to +23 dBm for a booster amplifier. Inline amplifiers typically run 15–25 dB of gain.

Noise figure for a well-designed EDFA is 4–6 dB in the C-band. This number is fundamental — it directly degrades OSNR at every amplifier stage, and since long-haul spans may have 20 or more amplifier sites, the cascaded noise figure is the dominant factor in system reach. A 6 dB noise figure EDFA across 20 spans degrades OSNR by roughly 120 dB·nm — that's a theoretical degradation that forces you into stronger FEC or shorter spans.

Pump laser requirements for EDFA are manageable. A 980 nm pump delivering 200–300 mW of optical power is standard for an inline EDFA. These pumps are single-mode InGaAs devices, well-understood, available from multiple suppliers, and typically rated for 25+ year MTBF at normal operating temperatures. The pump is inside the EDFA housing; the fiber plant doesn't need to carry pump light.

## How Raman Amplification Works

Raman amplification uses stimulated Raman scattering (SRS) in standard transmission fiber. A high-power pump laser — typically 500 mW to 1.5 W — is injected into the fiber span, either co-propagating or counter-propagating with the signal. The pump photons interact with molecular vibrations in the silica, downshifting in frequency by approximately 13 THz. If that downshifted frequency coincides with a signal wavelength, the signal experiences gain.

The most useful characteristic of Raman amplification: it can be distributed. Rather than a discrete amplifier at a point, the gain is spread across the entire fiber span. A counter-pumped Raman configuration injects pump light at the amplifier site and the gain occurs throughout the preceding 80 km of fiber, with the maximum gain accumulating in the last 20–30 km before the amplifier. This means the signal power in the middle of the span is lower than with lumped EDFA amplification — and lower signal power means less nonlinear impairments like cross-phase modulation and four-wave mixing.

The noise figure for Raman amplification is where it gets interesting. Distributed Raman can achieve an effective noise figure of 0 to -3 dB when the on/off gain (gain measured with pump on versus pump off) is 10–15 dB. That negative noise figure is only meaningful in the context of OSNR calculations — it represents that the signal degradation is less than what a theoretically ideal lumped amplifier would impose, because the signal never fell as low before being amplified.

The pump laser requirements are where Raman becomes difficult. You need 500 mW to 1.5 W of pump power per channel to achieve 10–15 dB of Raman gain in standard SMF-28. These pumps are high-power multimode Fabry-Perot or DFB devices, significantly more expensive and less reliable than EDFA pump lasers. The pump light travels through the transmission fiber — which means the connectors, splices, and any ROADMs in the path all interact with pump power. Raman-pumped spans require careful attention to fiber connectors; a contaminated connector heating up under 1 W of pump light is a genuine safety concern.

Raman amplification also creates gain tilt across the C-band. The peak gain frequency is fixed relative to the pump, but the gain is not flat across the signal band. Multi-pump Raman configurations — using two or more pump wavelengths — can flatten the gain profile, but this adds cost and control complexity.

## What You Cannot Swap

The systems implications of the pump location difference are profound. EDFA requires electrical power at each amplifier site. Raman can, in principle, allow you to skip electrical power at an intermediate site — a technique called "optically amplified remote repeater" — by propagating pump light from a far-end site. Submarine cable systems have used this since the 1990s. Terrestrial operators have used remote Raman pumping to avoid building access roads to intermediate sites in difficult terrain.

But you cannot just insert a Raman amplifier where an EDFA was. The fiber plant, channel power, OSNR budget, and gain equalization all need to be re-engineered. Raman gain is not flat, so gain-flattening filters designed for EDFA profiles will not compensate correctly. The dispersion accumulated before the Raman gain site is different from the lumped-gain case, affecting the nonlinear phase accumulated.

EDFAs cannot achieve negative effective noise figures. If your OSNR budget is already tight and you need lower noise, Raman is the tool — but not as a drop-in.

## The Hybrid Case That Actually Makes Sense

Ultra-long-haul systems — spans of 120 km or longer, or systems targeting 8,000+ km terrestrial reach — routinely combine distributed Raman preamplification with a conventional EDFA booster. The hybrid architecture works like this: Raman pumps at the amplifier site inject counter-propagating light into the span. The distributed gain amplifies the signal throughout the last 40 km of fiber before the amplifier, reducing the minimum signal power in the span and suppressing noise accumulation. Then an EDFA provides the bulk gain needed to compensate for the full 120 km of fiber loss.

The OSNR improvement from a hybrid configuration is typically 3–5 dB compared to EDFA-only on the same span. On a 20-span system, that 3–5 dB improvement either extends reach by several hundred kilometers or allows you to run higher-order modulation (say, 64QAM instead of 16QAM) at the same reach — which doubles the spectral efficiency and the capacity you can deploy on the fiber.

The Corning TrueWave RS fiber and OFS AllWave fiber, both common in North American terrestrial long-haul, have Raman gain coefficients well-characterized for this type of hybrid design. SSMF (G.652D) has a Raman gain coefficient of approximately 0.4 (W·km)^-1 at 1455 nm pump wavelength. Ultra-low-loss fibers like Corning SMF-28 Ultra or OFS TrueWave Reach have slightly different Raman gain profiles but the hybrid technique applies to all of them.

Vendors like Ciena (on the GeoMesh platform), Nokia (on the PSI-M), and Infinera design EDFA+Raman hybrid amplifier nodes as standard offerings for terrestrial systems over 80 km spans. The additional cost over a pure EDFA solution — primarily the high-power Raman pump modules and the associated safety interlock systems for the fiber — is justified whenever the alternative is building a new amplifier hut at a site where no infrastructure exists.

The choice between EDFA, Raman, and hybrid ultimately comes down to three numbers: span loss, OSNR target, and budget. EDFA works for the vast majority of cases. Raman becomes worth considering above 80 km spans or when OSNR margins are under 3 dB. Hybrid is the answer when both are true simultaneously.

title: "Why Your 400G DAC Cables Work at 3m But Not at 5m"
type: tutorial
target_audience: technical
score: 9/10
---

Direct Attach Copper cables at 400G have a physical cutoff point that is not a soft degradation but a hard failure boundary — a DAC cable that works perfectly at 3 meters will produce complete link failure at 5 meters under the same conditions, and the failure is not a flaky link or a marginal BER condition. It is a link that will not come up, or a link that comes up and immediately drops. Understanding why this happens requires understanding how PAM4 signaling interacts with the frequency-dependent attenuation characteristics of the coaxial or twinax copper medium, and why the number of signal levels in PAM4 makes this interaction far more consequential at 400G than it was at 100G with NRZ signaling.

Copper signal attenuation in the twinax medium used in SFP28, QSFP28, QSFP-DD, and OSFP DAC cables increases with frequency following a skin-effect model where attenuation in dB/meter scales approximately with the square root of frequency. At 26.5625 Gbaud — the symbol rate for 100G NRZ on a 4-lane QSFP28 DAC — the copper attenuation over a 5-meter 26 AWG twinax is approximately 18 to 22 dB depending on the specific cable construction. At the same cable length, a QSFP-DD 400G DAC operating at 53.125 Gbaud PAM4 per lane sees approximately 26 to 32 dB of insertion loss per lane, because the higher baud rate components of the PAM4 signal experience greater skin-effect attenuation. The SerDes and cable driver in the QSFP-DD module must overcome this with transmit equalization (pre-emphasis) and receiver equalization (CTLE and DFE) to reconstruct the original PAM4 signal at the receiver.

The equalization budget is finite and technology-specific. The receiver equalization in a QSFP-DD direct attach cable is implemented in the cable assembly's end connectors, not in the switch ASIC, because the host electrical interface for DAC cables is specified as a passive electrical specification — the cable assembly is responsible for meeting the signal integrity requirements at the host connector. The maximum equalization capability designed into typical QSFP-DD passive DAC cable assemblies supports insertion loss up to approximately 22 to 24 dB at Nyquist frequency (26.5625 GHz for 53.125 Gbaud PAM4). Below this loss limit, the cable assembly delivers a compliant signal to the host. Above it, the equalized eye remains open but with insufficient eye height and eye width to reliably decode PAM4 symbols with four distinct amplitude levels.

The reason the failure is sharp rather than gradual is the PAM4 amplitude level spacing. In a PAM4 signal with four amplitude levels — labeled 0, 1, 2, 3 — the spacing between adjacent levels is one-third of the total signal swing. After equalization that compensates for the bulk frequency roll-off but adds noise through the DFE tap adaptation, the effective noise floor relative to the inter-symbol spacing determines the symbol error probability. When the insertion loss is 22 dB (within equalization range), the equalized eye height at the decision threshold is above the noise floor with margin. When the insertion loss reaches 28 dB (beyond equalization range), the equalized eye height collapses to a small fraction of the noise floor and symbol error rate increases exponentially rather than gradually. This exponential behavior is why a 3-meter cable works and a 5-meter cable fails without a transitional zone of marginal performance.

The insertion loss versus length relationship for common AWG gauge twinax used in QSFP-DD DAC cables places the 22 to 24 dB Nyquist frequency insertion loss limit at approximately 3.0 to 3.5 meters for 26 AWG and approximately 4.0 to 4.5 meters for 24 AWG. This is why QSFP-DD passive DAC cables are typically available in 0.5, 1, 1.5, 2, and 3 meter lengths, but rarely in 4 or 5 meter lengths — the 4 to 5 meter range is where 26 AWG passive DAC cables fail and where 24 AWG passive DAC cables are at their limit. Manufacturers who sell 5-meter "passive" QSFP-DD DAC cables are either using 22 AWG cable (heavier, stiffer, harder to route in dense racks) or are actually selling active cables with integrated signal conditioning that they are labeling as passive for procurement simplicity.

Active Electrical Cables, also called active DAC or AEC, address the distance limitation by integrating a retimer or re-driver IC in the cable assembly connectors. The retimer fully reshapes the PAM4 signal, effectively resetting the signal integrity budget at each end rather than relying on passive equalization across the full cable length. AEC cables at QSFP-DD 400G support lengths of 5, 7, and in some implementations 10 meters, at the cost of power consumption — typically 1.5 to 2.0 watts per end connector, adding 3 to 4 watts total to the link power budget. AEC cables also require the host SerDes to operate correctly with the retimer's electrical interface characteristics, which is generally the case for production platforms but should be validated against the specific platform datasheet or QSFP-DD vendor qualification list. The latency of AEC cables is approximately 50 to 100 nanoseconds higher than passive DAC cables due to the retimer pipeline, which is irrelevant for most applications but matters for precision-timing applications and some high-frequency trading infrastructure.

Active Optical Cables at 400G QSFP-DD use the same form factor with optical fiber replacing the copper twinax core. AOC cables support distances of 10 to 100 meters and beyond, are immune to electromagnetic interference, and have consistent insertion loss across length that is not subject to the skin-effect copper attenuation penalty. The per-port cost premium over passive DAC is typically $80 to $150 for a 10-meter QSFP-DD 400G AOC versus $40 to $70 for a 3-meter passive DAC. For spine-leaf rack architectures where port-to-port distances are under 3 meters, passive DAC is the correct choice. For architectures where port-to-port distances range from 3 to 7 meters — as in some oversubscription-optimized pod designs where spine switches are mounted above the leaf switches with cable runs through overhead management — AEC fills the gap between passive DAC reach and AOC cost. For distances above 7 meters, AOC or structured optical cabling is the correct solution.

Specifying DAC cable lengths for spine-leaf port distances requires measuring actual port-to-port paths in the physical rack layout, not assuming a nominal rack-unit distance. A 3-meter cable specified for a port that is 14U above its peer in the same rack will need to route through a cable manager, potentially adding 0.5 to 0.8 meters of additional path length. A passive DAC specified at exactly 3 meters for a 2.6-meter measured port-to-port distance with cable management overhead becomes a cable that routes with cable ties creating 5 cm radius bends at every direction change — which does not cause electrical loss in passive copper DAC the way it would on optical fiber, but does cause mechanical stress at the connector boot over time. Specifying cables 0.5 meters longer than the measured path length gives routing latitude without pushing into the attenuation-limited length range.
