As demand for high-speed networks continues to grow in modern data centers, 200G network solutions have become an inevitable trend. HTF’s 200G PAM4 QSFP56 to 4xSFP56 passive direct attach cable addresses this need while offering excellent signal integrity and broad compatibility, making it a market-leading solution.
Architecture and Transmission Technology
The HTF 200G PAM4 QSFP56 to 4xSFP56 cable is based on a 4x50G or 4x56G architecture, supporting both NRZ (Non-Return-to-Zero) and PAM4 (Pulse Amplitude Modulation 4-level) transmission technologies. This flexibility allows the cable to support traditional NRZ signals while also enabling higher bandwidth efficiency through PAM4. PAM4 achieves double the transmission rate by sending four voltage levels per symbol period, thus facilitating higher data throughput over the same channel.
Signal Integrity and Cable Structure Optimization
Signal integrity is a core element in high-performance data transmission cables. HTF’s 200G PAM4 QSFP56 to 4xSFP56 cable features an optimized shielding design that effectively reduces crosstalk and insertion loss. The reduction in crosstalk ensures minimal electromagnetic interference between adjacent signal channels, maintaining stable data transmission. Lower insertion loss minimizes signal attenuation during transmission, ensuring high-quality signals even over longer distances.
Additionally, the cable adheres to the SFF-8636 standard, which guarantees compatibility between multi-vendor equipment and offers flexibility for future upgrades. This compatibility allows it to support 200G Ethernet and InfiniBand HDR standards, meeting the application needs of next-generation 200G switches, servers, routers, and other networking equipment.
Low Power Consumption and High Performance
Power consumption is a key factor to balance in network equipment for data centers. The HTF passive cable not only supports transmission speeds of up to 56Gbps using PAM4 but also boasts low power consumption, enhancing its advantages for deployment in high-density data centers. Low power consumption translates to less heat generation during data transmission, reducing the strain on cooling systems and improving overall energy efficiency.
Moreover, the cable supports hot-swappable functionality, which is crucial in data center operations. Maintenance personnel can plug and unplug the cable without interrupting system operations, significantly improving maintenance efficiency.
Optimized Transmission Distance and Temperature Adaptability
HTF’s 200G PAM4 QSFP56 to 4xSFP56 passive cable supports a maximum transmission distance of 3 meters, excelling in short-distance, high-performance interconnection applications. The passive structure eliminates the need for additional power to drive signals, resulting in a simple, efficient design that meets the needs of high-density cabling inside and outside racks in data centers.
In addition, the cable operates within a wide temperature range, from 0°C to 70°C. Whether in standard data center environments or extreme temperature conditions, this cable maintains stable performance.
Compliance with Technical Standards and Compatibility
The HTF 200G PAM4 QSFP56 to 4xSFP56 cable fully complies with Ethernet IEEE802.3bj and IEEE 802.3cd standards, enabling seamless compatibility with existing Ethernet equipment. Furthermore, the cable is RoHS certified, indicating compliance with environmental regulations regarding the restriction of hazardous substances during manufacturing.
EEPROM Support and Serial Number Identification
For easier management and maintenance, HTF’s cable integrates EEPROM support. The built-in EEPROM allows the system to automatically recognize each cable’s serial number and specifications, enabling more efficient asset management. This feature is particularly beneficial in data centers with extensive cable deployments, helping to reduce errors in equipment management.
In conclusion, HTF’s 200G PAM4 QSFP56 to 4xSFP56 passive direct attach cable stands out as an ideal solution for high-density deployments in data centers due to its high transmission speeds, superior signal integrity, and low power consumption. With support for 56Gbps PAM4 transmission technology, broad standard compatibility, and optimized physical design, this cable ensures efficient applications in data centers. HTF, through this cable, not only provides users with a high-performance solution that meets the requirements of next-generation 200G networks but also strengthens its position as a technology leader in high-speed optical communication.
