Know before you buy
Yes, this OptoSpan cable is specifically programmed and tested to ensure full compatibility with Dell QSFP+ ports, functioning just like an OEM-branded cable.
Absolutely. This cable is versatile and supports InfiniBand and Fiber Channel protocols, making it suitable for a variety of high-speed data center environments.
This specific model is 1 meter in length. Because it is a passive copper DAC, it is designed for short-reach, point-to-point connections within a single rack or between adjacent racks.
No, this is a plug-and-play solution. It utilizes an I2C serial interface for standard communication with your switch, so it should be recognized automatically upon insertion.
Passive copper DACs like this one offer the lowest power consumption and the most cost-effective performance for short-distance links. They are ideal when you need a simple, reliable connection without the extra cost of optical transceivers.
