The article reviews Kyocera AVX’s expansion of its capacitor lineup for high-speed optical communications. It focuses on new multilayer ceramic capacitors (MLCCs) built for 100G and 400G transceiver modules.
The piece explains how these parts help solve signal integrity and power delivery issues in compact, dense optical modules. That matters a lot for today’s data centers and telecom networks, where every millimeter and microsecond counts.
Advancing 100G and 400G transceiver performance
Kyocera AVX has broadened its MLCC portfolio with devices that meet the tough demands of next‑generation transceivers. The new capacitors offer low inductance and stable capacitance at high frequencies, making them useful for decoupling and noise suppression on power rails.
They reduce equivalent series inductance (ESL) and equivalent series resistance (ESR). That means better power integrity and cleaner signal paths—critical for high-speed data in tight spaces.
These capacitors target miniaturized form factors like CFP2, QSFP‑DD, OSFP, and other pluggable transceivers. Space and thermal constraints are big concerns here.
Kyocera AVX points out their parts keep working well across temperature changes and under high current. That’s key for reliable operation in dense optical modules and demanding data-center environments.
The mix of advanced materials and construction gives strong decoupling at the frequencies common to 100G and 400G links. The industry keeps chasing higher bandwidth per lane and denser port counts, and these capacitors fit right in.
- Low ESL/ESR for better decoupling on high-speed rails
- Stable high-frequency capacitance to help preserve signal integrity
- Temperature tolerance across operational ranges
- High current capability for power delivery in dense modules
- Works with automated assembly and reflow soldering
Design and materials for high-frequency decoupling
The new MLCCs use advanced materials and construction to cut down ESL and ESR, while holding capacitance steady at the frequencies 100G/400G transceivers need. That leads to tighter noise suppression and better decoupling on multiple power rails.
It helps reduce voltage swings during heavy data transmissions. You get more reliable operation under changing loads and temperatures—a must for new telecom gear and massive data centers.
Manufacturing readiness and form-factor compatibility
Kyocera AVX says their MLCCs work with automated assembly lines and reflow soldering, which are standard in transceiver manufacturing. They fit into the small footprints of CFP2, QSFP‑DD, OSFP, and similar modules, and don’t sacrifice performance.
This compatibility with existing production helps speed up time-to-market for 400G and beyond. It also supports the push for higher density and lower thermal budgets in optical networking gear.
Implications for data centers and telecom networks
The launch of these high-speed MLCCs comes as the industry races toward 400G and higher bandwidth per lane. For hyperscale data centers and carriers, packing more ports into the same space—while protecting signal and power integrity—is a big deal.
Kyocera AVX pitches these capacitors as a way to boost module reliability and extend lifecycle, which could mean less maintenance and fewer replacements for critical networking gear.
Reliability, lifecycle, and temperature considerations
They claim strong operational reliability across temperature ranges and under high current. The combo of low ESL/ESR and steady high-frequency performance improves decoupling, which helps prevent voltage spikes and power‑rail collapse during heavy workloads.
This kind of reliability is pretty valuable for hyperscale environments that want predictable lifecycles, even in tough thermal conditions and across thousands of modules worldwide.
Strategic outlook for next-generation networks
As data centers and carriers move toward 400G and beyond, Kyocera AVX’s specialized MLCCs step in to reinforce the ecosystem. These passive components are tuned for the fastest optical links out there.
The focus on compatibility with standard manufacturing processes matters a lot. Compact module form factors fit right in with the industry’s push for denser, more capable transceivers.
Network operators and equipment makers get a real shot at better reliability and efficiency with these capacitors. That smoother transition to high-speed optical networking? It’s looking more achievable than ever.
