200G QSFP-DD to 2x100G QSFP28 DAC

Product Overview

The 200G QSFP-DD to 2x100G QSFP28 DAC is a high-performance, high-speed direct-attach cable designed specifically for 200G and 100G network environments. It enables high-speed signal conversion and transmission from a 200G QSFP-DD port to two 100G QSFP28 ports. The product is rigorously designed and manufactured in compliance with industry standards such as QSFP-DD MSA, QSFP28 MSA, IEEE802.3Bj, and SFF-8636, ensuring excellent signal transmission stability and compatibility. It also offers a variety of wire gauges ranging from 26 to 30 AWG, supports up to 5 meters of transmission distance, and can be customized with either PVC or LSZH jacket materials. Featuring low-power consumption and an EMI-resistant design, it operates within a temperature range of 0°C to 70°C and is available in an industrial-grade version, making it widely compatible with various network devices and scenarios, including 200G Ethernet, switches, servers, routers, supercomputing centers, and cluster networks.

Core Technical Features

This high-speed direct-attach cable leverages mature high-speed signal transmission technology to precisely meet the requirements of multiple protocol specifications, ensuring signal transmission compatibility across different devices. With a diverse selection of wire gauges from 26 to 30 AWG, it balances transmission distance and wiring flexibility: smaller-gauge cables are lighter and ideal for short-distance, high-density cabling, while larger-gauge cables support up to 5 meters of transmission, suitable for deployments with greater device spacing. Optional PVC and LSZH jacket configurations cater to varying safety and environmental needs; LSZH jackets, which are low-smoke, halogen-free, are particularly well-suited for data centers, supercomputing centers, and other facilities with stringent fire-safety requirements.

In terms of performance, the product supports 8x25G EDR and 8x14G FDR transmission rates. Its low-power design effectively reduces overall equipment energy consumption, lowering operating costs and thermal management burdens. The EMI-resistant design efficiently shields against external electromagnetic interference while preventing its own signals from affecting neighboring devices, ensuring stable and clean signal transmission—even in densely packed equipment clusters—maintaining reliable network connectivity. A working temperature range of 0°C to 70°C meets standard data center requirements, while the industrial-grade version accommodates more demanding high- and low-temperature outdoor or industrial environments, further expanding the product’s application scope.
