March 16, 2026

MACOM Technology Solutions today introduced the MACD‑41804 Cable Driver with Equalizer, a copper‑based interconnect that delivers low‑power, high‑density connectivity for next‑generation scale‑up applications. The driver incorporates input equalization, a broad dynamic range, optional gain adaptation, and mission‑mode diagnostics, positioning it as a cost‑ and power‑efficient alternative to retimed architectures.

The MACD‑41804 supports the 1.6 T OSFP form factor and is built on a bumped die in compact flip‑chip packaging, enabling high‑volume manufacturing while maintaining tight signal integrity. Its integrated equalizer and diagnostics allow it to maintain performance across a wide range of cable lengths and signal conditions, making it suitable for data‑center, industrial, defense, and telecommunications deployments.

MACOM’s strategy emphasizes high‑performance scale‑up architectures that leverage copper interconnects to reduce power consumption and latency compared to optical solutions. By offering a driver that can be integrated into existing copper infrastructures, MACOM expands its portfolio of photonics, optoelectronic, and copper interconnect products, reinforcing its position in AI, machine‑learning, and cloud‑computing markets.

The company will demonstrate the MACD‑41804 at OFC 2026 in Los Angeles from March 17 to 19. MACOM’s recent financial health—gross margin of 55.22%, net margin of 15.88%, a current ratio of 3.96, and a debt‑to‑equity ratio of 0.39—underscores its capacity to invest in and support new product introductions while maintaining strong operational leverage.
