SpecificationsFeaturesApplicationsVideosDatasheetsFAQsInquirySpecifications Overview of 1.6T OSFP-XD DAC Ethernet and InfiniBand Cable (0.5-1 meter, Passive, OSFP-XD to OSFP-XD, 25AWG) Maximize your data transfer speed and network reliability with our Custom 1.6T OSFP-XD DAC Cable, designed for both Ethernet and InfiniBand connections. This high-performance passive cable supports up to 1.6 terabits per second (T) of bandwidth, making it ideal for high-density data centers, cloud computing, and network environments requiring ultra-fast, low-latency connections. 1.6T OSFP-XD passive copper cable assembly feature sixteen differential copper pairs, providing 16 data transmission channels at speeds up to 100Gbps per channel, and meets 1.6T Ethernet and InfiniBand eXtended Data Rate(XDR) requirements. Available in 25AWG wire gauges, this 1.6T copper cable assembly features low insertion loss and low crosstalk. 1.6T OSFP-XD passive copper cable uses PAM4 signals for transmission, which doubles the rate. However, there are more stringent requirements for cable insertion loss. For detailed requirements, please see High Speed Characteristics. Available in customized configurations, COMNEN’s 1.6T OSFP-XD DAC cables can be tailored by length, labeling, firmware tuning, thermal features, and mechanical design to suit specific application environments. Whether you’re optimizing infrastructure for cloud computing, hyperscale networks, or AI workloads, this active copper solution offers a cost-effective, low-latency, and high-reliability connection tailored to your needs.

While both share the same heritage, OSFP-XD is specifically engineered to meet the extreme bandwidth and thermal requirements of next-generation AI and Hyperscale data centers. 1. Key Technical Differences Feature OSFP (Standard) OSFP-XD (Extra Density) Max Bandwidth Up to 800G Up to 1.6T (1600G) Electrical Lanes 8 Lanes (100G per lane) 16 Lanes (100G or 200G per lane) Connector Rows Single Row of contacts Dual Row (Stacked) contacts Thermal Capacity 15W – 18W 33W – 40W Port Density High Ultra-High (Doubles throughput per 1U) 2. Detailed Comparison A. Connector Architecture (The “XD” Factor) The most significant difference lies in the electrical interface. Standard OSFP utilizes 8 high-speed electrical lanes. To reach 1.6T without increasing the physical width of the module, OSFP-XD utilizes a dual-row contact design, effectively doubling the number of electrical lanes to 16. This allows a single 1.6T port to handle the traffic that previously required two 800G ports. B. Signal Integrity & 224G PAM4 As the industry moves toward 224G PAM4 signaling, signal degradation becomes a critical challenge. OSFP-XD is designed with tighter tolerances and enhanced shielding to manage the increased complexity of 16-lane configurations, ensuring that BER (Bit Error Rate) remains within acceptable limits for InfiniBand and Ethernet applications. C. Superior Thermal Management 1.6T optics generate significant heat (often exceeding 25W). The OSFP-XD form factor preserves the “integrated heat sink” advantage of the original OSFP but optimizes the airflow path and surface area. This allows OSFP-XD to dissipate up to 40W per module, which is essential for maintaining performance in high-radix switches without thermal throttling. D. Backward Compatibility One of the strategic advantages of OSFP-XD is its mechanical compatibility. OSFP-XD connectors are designed so that a standard 8-lane OSFP module can often be plugged into an OSFP-XD slot (depending on the cage/host design), providing a flexible migration path for data center operators.
