100G QSFP28 DAC high-speed cable classification introduction and solutions
With the rapid development of the network, the market demand for high bandwidth and high reliability is also increasing, so the high-speed interconnection solution of the DAC high-speed cable is emerging. The following introduces the 100G QSFP28 DAC high-speed cable.
What is a DAC high-speed cable:
DAC high-speed cable (Direct Attach Cable) is generally translated as direct cable or direct copper cable. It is usually a cable assembly with fixed purchases and fixed connectors at both ends. The port cannot be replaced, and the module head and the copper cable cannot be separated. Widely used in storage area networks, data centers, and high-performance computer connectivity.
100G QSFP28 DAC high-speed cable product features:
- Compliant with SFF-8636 standard
- Support Ethernet IEEE802.3Bj protocol
- Using I2C two-wire serial interface, easy to control and monitor
- Can support hot swap
- Low crosstalk, low power consumption
100G QSFP28 DAC high-speed cable products:
High-speed cables are suitable for stacking, cascading and direct connection between short-distance 100G devices, such as 100G switches, etc.; they can provide customers with 100G high-bandwidth data interconnection capabilities, and provide 4-way duplex channels. It supports up to 25Gb/s, and the aggregation bandwidth is 100Gb/s; it complies with the SFF-8436 specification and is applied to the connection between devices with QSFP28 ports.
High-speed cable is suitable for interconnection between 100G and 25G devices; one end is 100G QSFP28 interface, and the other end is 4 25G SFP28 interfaces, which can provide customers with 100G high-bandwidth data interconnection capability; Compliant with SFF-8665/SFF-8679 , IEEE 802.3bj and InfinibandEDR standards;
It supports a distance range of 1 meter to 5 meters, and is widely used in data center or supercomputing center system scenarios.
