Regulatory and Compliance Information

The QSFP-H40G-CU1M= is a Cisco 1 meter long 40G QSFP+ passive copper cable. As such, it is subject to a variety of regulatory and compliance requirements, including:

  • Safety: The QSFP-H40G-CU1M= cable must comply with various safety regulations, including the UL 94 flammability standard, which measures the flame-retardant properties of materials.
  • Electromagnetic Compatibility (EMC): The cable must meet EMC requirements, which limit the amount of electromagnetic interference that the cable can emit or receive. EMC compliance is typically measured by various international standards such as CISPR, FCC, and CE.
  • RoHS: The QSFP-H40G-CU1M= cable must comply with the European Union's Restriction of Hazardous Substances (RoHS) directive, which limits the use of hazardous substances such as lead, mercury, and cadmium in electronic equipment.
  • REACH: The cable may also be subject to the European Union's Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulation, which requires the registration, evaluation, and authorization of chemicals used in products.

Cisco designs its products to meet or exceed these and other regulatory requirements. Cisco products undergo rigorous testing and certification to ensure compliance with relevant regulations.

Maximum Transmission Distance

The QSFP-H40G-CU1M= Cisco 1 Meter Twinaxial Network Cable is a 40 Gigabit Ethernet direct-attach copper (DAC) cable designed for use in high-speed data center applications. The maximum transmission distance of this cable is 1 meter or approximately 3.28 feet.

Twinaxial cables like the QSFP-H40G-CU1M= use a pair of copper wires to transmit data, which makes them ideal for use in short-distance applications within a data center environment. In addition, twinaxial cables are passive and do not require any external power source or equipment for operation.

It's important to note that the maximum transmission distance of a cable can be affected by various factors, including the quality of the cable and the networking equipment being used. Therefore, it's important to consult the product specifications and guidelines to ensure that the cable is suitable for your intended application and environment.

Performance and Reliability

The QSFP-H40G-CU1M= is a Cisco 1 meter long 40G QSFP+ passive copper cable designed for use in high-performance data center environments. This cable is designed to provide reliable and high-speed connectivity between networking equipment, including switches, routers, and servers.

The QSFP-H40G-CU1M= cable uses a twinaxial copper design, which provides high-speed data transfer with low latency. This design allows for fast data transfer rates of up to 40 Gigabits per second (Gbps) using four 10 Gbps channels. Compared to optical cables, copper cables like the QSFP-H40G-CU1M= are generally less expensive and do not require special handling or installation considerations.

In terms of reliability, the QSFP-H40G-CU1M= cable is a passive copper cable, which means it does not require any additional power or cooling. This can make it a more reliable option compared to active copper cables, which require power to operate and may be more prone to failure.
