QSFP28 1X1 Connector Ultimate 100G High Speed Single Port S5C21H0A00BA4

Product Overview

As the “Ultimate Density Choice” in Vitalconn’s portfolio, the S5C21H0A00BA4 is engineered to break physical limits by integrating four high-speed lanes into a single single-port form factor. It serves as the core physical foundation for next-generation backbone networks, providing the bandwidth necessary for compute-intensive tasks like AI large-model training and real-time inference. This connector is natively backward compatible with standard high-speed modules, protecting prior hardware investments while enabling a smooth evolution to 400G and beyond.

Packing Details

Following standard high-protection protocols for single-port solutions, these components are packaged in blister trays. To ensure maximum component safety and shipping efficiency, adjacent units within the tray or trays within the master carton are placed at a 180-degree horizontal orientation relative to each other.

FAQ

Q1: How does the QSFP28 architecture help save rack space? A: By integrating 4 independent 25G channels into a single single-port connector, the S5C21H0A00BA4 provides 100G of total bandwidth in a compact footprint. This allows a standard 1U networking device to achieve TB-class switching capacity, significantly reducing space and power costs.

Q2: Can this connector prevent 100G transceivers from overheating? A: Yes. It uses a precision “open-frame” top-punch array that maximizes natural air convection. This design breaks the thermal buildup seen in traditional closed structures and has been measured to lower operating temperatures by 5-8°C, preventing performance throttling.

Q3: Is the S5C21H0A00BA4 backward compatible with my current infrastructure? A: Absolutely. The QSFP28 series is designed with a bridging flexibility that is backward compatible with SFP+ standards. This enables the smooth reuse of existing infrastructure while providing a scalable path to 400G networks without requiring a hardware rework.
